I am trying to schedule my python code (.py) to run in Windows 10 using task scheduler. In order to do so, I need to indicate where my python.exe file is located.
I downloaded the latest Anaconda to my Windows 10 machine and run my code in jupyter notebook successfully so I should have python.exe somewhere.
I cannot find where the "python.exe" file path is stored in my computer. Thoughts?
Please see sample example below:
You can get it quite easily using the os module:
First open a Python interpreter, not through terminal but directly (there should be a shortcut on your start menu).
Next get the os module:
import os
And use the getcwd() method to find it:
os.getcwd()
The better way to do it. If Python is added to path.
Open a command prompt window. Not the Python interpreter or open Power Shell and type:
where python
Another way to do it is to type python.exe in the file explorer search bar at C:.
Get yourself a copy of Search Everything and type python.exe into its search box. That will find all Pythons available on your PC.

I have encountered an error while try to run a python 3.6.4 script after upgrading from 2.7.
I had initial installed both python 2.7 and 3.6 but them deleted 2.7 because I had no use for it and i am not getting this error.
I have tried:
Reinstalling python 3.6.4
changing the install location of said install
Repairing the python 3.6 install
Error:
A Python script by itself is not an executable program. So if you want to run the script Evosim.py by just entering Evosim.py in the command line, the .py file ending needs to be associated with the Python interpreter. It seems that currently in your system this is not the case.
There are two ways to deal with your situation:
Start your script by entering python Evosim.py instead of only Evosim.py in the command line.
Fix the broken association of the .py file ending with the Python interpreter. The answers to this question migth help you with that.
Solution #1
Go to your registry by searching regedit.
Open category HKEY_CLASSES_ROOT. Select .py. If .py don't exists then make it by yourself.
Double click the Default. It will make a popup. Change its value to Python.IDLE and click OK. Make a new String key in .py naming Content Type with value text/plain.
Solution #2
If the above method don't works then just go ahead and reinstall your python (also uninstall Python Launcher). Your modules and files will be at their place.
You can now open .py files.
Running command prompt as an administrator resolved my issue, and able to execute my python script
1). Right click any python file
2). Click Open with then Choose another app
3). Click on More apps then Look for another app on this PC. It should open up file explorer
4). Select python.exe wherever it is located.
A sample path is C:\Users\<user>\AppData\Local\Programs\Python\Python38\python.exe for a user installation. A way to check this path is by typing where python into cmd; it will list all installations of Python.
Now the python.exe you chose is associated with all .py files and typing file.py should not give an error.
I just downloaded and installed Anaconda on my Windows computer. However, I am having trouble executing .py files using the command prompt. How can I get my computer to understand that the python.exe application is in the Anaconda folder so it can execute my .py files?
You should use Anaconda Prompt instead of common Windows command prompt.
Then navigate to your folder with the .py file and run:
python myfile.py
However if you want to use normal command prompt you should put the path with you're python.exe which is usually in
C:\Users\<username>\AppData\Local\Continuum\anaconda3\python.exe
behind this one put your .py file.
Launch JupyterLab from Anaconda
(Perform the following operation with JupyterLab ...)
Click on icon folder in side menu
Start up "Text File"
Rename untitle.txt to untitle.py (The name of the file started up was also changed)
Start up the "terminal" (In windows the power shell starts up)
Execute the command python untitle.py
Right click on a .py file and choose 'open with'
Scroll down through the list of applications and click something like 'use a different program'
Naviage to C:\Users\<username>\AppData\Local\Continuum\anaconda3
click on python.exe and then click on 'ok' or 'open'
Now when you double click on any .py file it will run it through Anaconda's interpreter and therefore run the python code.
I presume if you run it through the command line the same would apply but perhaps someone could correct me?
Just get to the home of jupyter notebook and select "New" then select "Text file".
Then save the text file as file_name.py
Write your code in the file and save the file.
Then open the "Anaconda Prompt" and then type as follows to run your file
python file_name.py
You can do it from the "Anaconda Prompt"
conda run "my_script.py"
I was doing exactly as Martin Bosch suggested, and was getting the following:
(base) C:\>python command.py
python: can't open file 'command.py': [Errno 2] No such file or directory
I solved it this way:
navigate to the exact file location using the "cd" command
for me this was:
(base) C:\>cd my_scripts
this should put you specifically in the file where your .py script is located.
now you should try to input the name of your file.
(base) C:\my_scripts> test_script.py
you may get asked which program to run this with, and simply find python.exe
After doing this process once, I can simply type (in anaconda prompt)
test_script.py
and it runs no problem, even from the top of the file tree (I don't have to be in the exact file, nor do I have to explicitly give the whole file path)
Anaconda should add itself to the PATH variable so you can start any .py file with "python yourpythonfile.py" and it should work from any folder.
Alternatively download pycharm community edition, open your python file there and run it. Make sure to have python.exe added as interpreter in the settings.
If you get the following error:
can't open file 'command.py': [Errno 2] No such file or directory
Then follow this steps to fix it:
Check that you are in the correct directory where the Python file is.
If you are not in the correct directory, then change the current working directory with cd path. For instance: cd F:\COURSE\Files.
Now that you are in the directory where your .py file is, run it with the command python app.py.
Check where is the directory for the ananconda environment directory which is generally
"C:\Users\[UserName]\.conda\envs\[conda environment directory]"
You will see python.exe in that directory.
After that, you need to use the following command to execute your python file (i.e. xx.py) when you are running Anaconda prompt and you will be done:
"C:\Users\[UserName]\.conda\envs\[conda environment directory]\python.exe" xxx.py
BTW, if you have global variable (i.g. variable yyy) that contain directory, you have to define the global variable that contains full path of directory just below the header (the import section) to prevent the "name 'yyy' is not defined" error to occur:
from pathlib import Path # dealing with path issue
yyy = Path("[DriverLettter]:\Full\Path\of\Directory")
I have recently installed the Anaconda distribution on Windows 7 (Anaconda 3-2.4.0-Windows-x86_64). Unlike IDLE, I can't right-click and open a py file in the Spyder IDE. I will have to open Spyder first and then navigate to the file or drag and drop it in the editor. Is there any way to open the file in the editor directly from Widows Explorer?
With the current version of Anaconda (4.1.0) you can simply right-click on a python script in Windows File Explorer and choose "Open with". The first time you do this you need to select "Choose default program" and then browse to spyder.exe in the Script directory in your Anaconda installation. Also make sure that the "Always use the selected program to open this kind of file" is unchecked and then click OK. From now on spyder.exe will always be listed as one of the options when you select "Open with" from the right-click menu in Windows File Explorer.
I have had a similar problem with another piece of software that I use.
My work around for this problem is to set the file association for .py files to C:\Anaconda\Scripts\spider-script.py via the Open with dialog. If you now try to open your File.py by double clicking you'll receive an error like
~\file.py is not a valid Win32 application.
This can be resolved by editing the spyder-script.py registry key:
HKEY_USERS\S-1-5-21-3559708500-1520960832-86631148-1002\Software\Classes\Applications\spyder-script.py\shell\open\command
and replacing the default value "C:\Anaconda\Scripts\spyder-script.py" %1 with "C:\Anaconda\python.exe" "C:\Anaconda\Scripts\spyder-script.py" %1. Use the search function for this key if the path isn't the same for your machine, and of course use the appropriate path for your python installation. spyder-script.py should now execute in a python shell.
From the docstring of ftype,
...Within an open command string, %0 or %1 are substituted with the file name being launched through the association.
(Spyder maintainer here) This functionality is available as part of our Windows installer. In other words, if you install Spyder with it, then you'll see a new entry in the Open with menu of the Windows Explorer that allows you to open Python files directly on Spyder.
Unfortunately, it's not possible for us to do the same for other installation methods (i.e. when using Anaconda or pip). That's why it's necessary to resort to different hacks, as the ones mentioned in other answers here, to have this functionality for them.
What is working very well for me in Windows (10), is associating the *.py files with a batch file (let's say "SpyderBATCH.bat") containing this line :
[ANACONDA_FOLDER_PATH]\pythonw.exe" "[ANACONDA_FOLDER_PATH]\cwp.py" "[ANACONDA_FOLDER_PATH]" "[ANACONDA_FOLDER_PATH]/pythonw.exe" "[ANACONDA_FOLDER_PATH]/Scripts/spyder-script.py" %1
Where [ANACONDA_FOLDER_PATH] has to be replaced with the full path to the Anaconda folder (usually under "Program Files").
What Windows does, when double-clicking on a python script (let's say "file.py"), is pass to SpyderBATCH, as parameter number %1, the full path to "file.py".
Then Spyder is launched and displays the script "file.py" in the editor view.
I figured I would post my solution for this as well.
I have Spyder installed in multiple different environments. You can't simply call the spyder-script.py script without errors, because the environment must be activated.
#echo off
call [YOUR_CONDA_PATH]\Scripts\activate.bat [YOUR_CONDA_PATH]
call conda activate [YOUR ENVIRONMENT]
call start [YOUR_CONDA_PATH]\envs\[YOUR ENVIRONMENT]\pythonw.exe "[YOUR_CONDA_PATH]\envs\[YOUR ENVIRONMENT]\Scripts\spyder-script.py" %1
You can remove the second line and remove the environment extension from the third line if you have Spyder installed in your base environment.
Hopefully for anyone experiencing any weirdness with the other solution, this one will do the trick by activating the environment correctly.
The solution from JoeB152 worked perfectly for me!
If you are interested in adding the spyder icon (or any other) to the .py-files and if you would like to avoid the cmd-pop-up, I found out the following workaround which is feasible without admin rights:
Download the portable version of Bat To Exe Converter (I used v3.0.10).
Open your custom .bat-file in the Bat to Exe Converter.
In the options settings, activate "Icon" and give the path to the respective icon (for me it's in: .../AppData/Local/Continuum/anaconda3/Scripts/spyder.ico).
Set Exe-Format to Invisible (no empty cmd window would pop up anymore)
Convert your .bat-file to an .exe-file.
As usual, set to open .py-files with the newly created .exe.
Enjoy!
Environment:
Windows 10,
Conda 4.8.2,
Spyder 4.0.1,
Python 3.7
This problem is related to anaconda installation defaults - it does not register itself in PATH by default an dicourages users to do so. After proprly registering all directories in path, spyder.exe works as expected.
How to know, what to register?
locate and activate.bat an run it in cmd, then run echo %PATH% and manually register all directories mentioning anaconda.
Alternatively, reinstall anaconda with PATH registratin enabled.
Then you can associate .py files wit spyder.exe and association will work.
System: Windows 11, Python 3.9.7 (Installed through Anaconda3)
This solution will allow you to double click .py files and have them open in the Spyder in the environment of your choice, but does NOT associate .py files with the icon for Spyder.
I'm answering because it took me over an hour to understand & piecemeal together all the (great) solutions that are provided in this thread to get something that works (thanks Martin Sorgel, JoeB152 and Max-K).
NOTE: Some commentors above say to use a Bat-to-Exe converter & that will let you get the icon too.. but, DON'T! All of the ones you're finding via google have got some bad malware in them and my computer ended up deleting the .exe's I was making using that method because they had a Trojan in them.
Full Solution:
STEP 1: Make a .bat file that will launch Spyder in a specific environment.
1.1 Open a plain text editor (e.g. Notepad, etc.) and copy/paste the text below into it.
#echo off
call [YOUR_CONDA_PATH]\Scripts\activate.bat [YOUR_CONDA_PATH]
call conda activate [YOUR ENVIRONMENT]
call start [YOUR_CONDA_PATH]\envs\[YOUR ENVIRONMENT]\pythonw.exe "[YOUR_CONDA_PATH]\envs\[YOUR ENVIRONMENT]\Scripts\spyder-script.py" %1
Update [YOUR_CONDA_PATH] in the text above with the path to Anaconda3 on your computer. Mine was C:\Users\myusername\Anaconda3\ & yours is likely similar.
1.2 Save this new file as spyderlaunch.bat and place it on your computer somewhere that you'll NEVER move it (otherwise you'll have to do STEP 2 each time you move this file. I save mine in a python_env_settings folder where I keep info on what packages I installed manually in my different environments).
NOTE: JoeB152 says you can remove the second line and remove the environment extension from the third line of the text above if you have Spyder installed in your base environment. I'm not sure if this works...
1.3 Make sure your new .bat files works! It works if when you double click on spyderlaunch.bat, that it launches and opens Spyder in the environment you want it to! (Spyder will show the environment it opens in on the bottom right hand side: ).
STEP 2: Tell your computer to associate (i.e. open) all .py files with the spyderlaunch.bat file you just created.
2.1 Open an Anaconda Terminal with "run as an administrator" (by right clicking on the application) and run the following 2, separate commands. Update[PATH_TO_YOUR.batfile] to wherever you saved spyderlaunch.bat in 1.2.
assoc .py=Python
ftype Python="[PATH_TO_YOUR.batfile]" "%1" %*
Errors?
If you don't run the Anaconda Terminal application as an administrator you will be denied access to associate .py=Python. If that's not your issue, then check that the spaces and quotation marks are exactly where they appear above. In particular, you may want to make sure there is a space in between the quotation marks around [PATH_TO_YOUR.batfile] and those around %1.
I was unable to find a spyder.exe on my installation of conda. However in my users/.anaconda/navigator/scripts I found a spyder.bat file. Using this to open the file opens an anaconda prompt and shortly after spyder will open the file. The file icon is broken but it works for me. Hope this might help.
(Comment in relation to the responses by JoeB152 and Jessica Haskins - I am new, so I cannot leave comments)
I found that their suggested .bat file works once you copy-paste the following file from A to B:
A) C:\Users\USERNAME\Anaconda3\Scripts\spyder-script.py
B) C:\Users\USERNAME\Anaconda3\envs\ENVRIONMENT_NAME\Scripts\
...where ENVIRONMENT_NAME is the name of your environment, such as main or test.
The .bat file contains:
#echo off
call C:\Users\bloggsj\Anaconda3\Scripts\activate.bat C:\Users\bloggsj\Anaconda3\
call conda activate C:\Users\bloggsj\Anaconda3\
call start C:\Users\bloggsj\Anaconda3\envs\main\pythonw.exe "C:\Users\bloggsj\Anaconda3\envs\main\Scripts\spyder-script.py" %1
Then associate .py files with that .bat file (e.g., via the 'Open with...' dialogue).
Alternatively, you could try using in the last line of the .bat file the file path: "C:\Users\bloggsj\Anaconda3\Scripts\spyder-script.py"
Get Spyder by itself:
https://docs.spyder-ide.org/current/installation.html
Set your default file opener to your newly installed spyder
To be able to add packages:
Make sure Anaconda is installed.
Go to Spyder preferences
Go to Python interpreter
Select: "Use the following Python interpreter"
Select file path with Anaconda and hit apply
Now you should be able to open files directed using Spyder and update your environment using Anaconda.
I made a batch utility spy.bat for this (not in the Anaconda directory)
spy.bat
call E:\Anaconda3\Scripts\activate.bat E:\Anaconda3
e:\Anaconda3\python.exe e:\Anaconda3\Scripts\spyder-script.py %1
Then, I associated the .py file type in Windows with this batch file as:
Right click any .py
Choose 'Open With' -> 'More Apps' -> 'Search on your PC' ->'select spy.bat'
In the spy.bat:
E:\Anaconda3 is my Anaconda installation directory.
First line starts the environment (Anaconda prompt).
Second line starts the spyder-script. %1 is to open the pyscript you want to open.
I've downloaded python installer from http://www.python.org/ftp/python/3.1.2/ , this python-3.1.2.msi file, I need to execute some python files? How do I do that? For example in php I'd do php filename.php from console, I do however have python command line but I don't know how to execute those files.
So if I could set ENV variable to directly execute my file(s) if that is possible that would be great.
There is an option in the installer called "Register Extensions" to associate Python files with the interpreter, so double-clicking them or entering filename.py in the console should work.
Apart from that you might want to add C:\Python31 to your PATH variable (right-click on My Computer, choose Settings, choose the Advanced Tab - there you can access the system variables. Better do this as an admin.
If you type python in the Windows command line, what happens? Is the Python interpreter in your PATH yet?
If not, add the Python installation directory there (here's a good guide). Then just do python script.py just like with PHP.
you can just execute
python yourfile.py
Or if the python command don't work you have to give the absolute path to you python installation or add it to windows path
Does anyone know how to associate the py extension with the python interpreter on Mac OS X 10.5.7? I have gotten as far as selecting the application with which to associate it (/System/Library/Frameworks/Python.framework/Versions/2.5/bin/python), but the python executable appears as a non-selectable grayed-out item. Any ideas?
The python.org OS X Python installers include an application called "Python Launcher.app" which does exactly what you want. It gets installed into /Applications /Python n.n/ for n.n > 2.6 or /Applications/MacPython n.n/ for 2.5 and earlier. In its preference panel, you can specify which Python executable to launch; it can be any command-line path, including the Apple-installed one at /usr/bin/python2.5. You will also need to ensure that .py is associated with "Python Launcher"; you can use the Finder's Get Info command to do that as described elsewhere. Be aware, though, that this could be a security risk if downloaded .py scripts are automatically launched by your browser(s). (Note, the Apple-supplied Python in 10.5 does not include "Python Launcher.app").
The file associations are done with the "Get Info". You select your .PY file, select the File menu; Get Info menu item.
Mid-way down the Get Info page is "Open With".
You can pick the Python Launcher. There's a Change All.. button that changes the association for all .py files.
Steve, add the following to the top of your python script:
#!/usr/bin/env python
It must occur as the first line of the file.
Then make the file executable as so:
daves-macbookpro ~: chmod +x foo.py
Then all you need to do to run this is type
./foo.py
The default python installation (atleast on 10.6.8) includes the Python Launcher.app in /System/Library/Frameworks/Python.framework/Resources/, which is aliased to the latest/current version of Python installed on the system. This application launches terminal and sets the right environment to run the script.
