I have a Python (.py) file and need to execute it from AutoIt. How can I do this?
Python scripts can be executed from command line. For a script called myscript.py, you can run it (assuming Python is installed) by typing:
python myscript.py
If you want to run myscript.py without having to prefix it by python, then set the path to the Python binary (e.g. C:\Python27\Python.exe) as Windows environment variable. This enables AutoIt to execute the Python script as if it were an external program. Reference: ShellExecute().
ShellExecute("myscript.py")
Point to where myscript.py resides of course. Use:
RunWait("C:\Python27\Python.exe myscript.py")
to avoid setting environment variables.
RunWait("C:\Python27\Python.exe filename.py")
this code working fine run from autoit

Recent versions of Python include a py.exe launcher that will interpret Unixy shebang lines like #!/usr/bin/env python3 and run the script appropriately. If you associate .py files with py.exe you can even run them directly from a shell (e.g. Powershell) like this:
./myscript.py
Unfortunately it still seems to run the script in a new window. Is there any way to make it output to the current shell without having to run py myscript.py?
I'm converting all my Python2 scripts to work with Python3.
From within a bash wrapper, scripts can be executed with Python3 with:
python3 myScript.py
However, I have an old wrapper which called a Python2 script via the shorthand, i.e
./myScript.py
How do I ensure that this shorthand will run the script with Python3 by default?
The server these scripts are running on is Ubuntu 14.04.
You can use the "hash-bang" #!/usr/bin/python3
more information regarding your operating system would be helpful. If you are on linux or mac you can add the following to the first line of your script:
#!/usr/local/bin/python
adjusting for the location of your python3. Then you could change the file to executable using:
chmod u+x script
After this you would be able to run your script with just
script
I have a python script which I am distributing in several nodes. I have python 2.6 installed in /usr/bin by default and have python 2.7 in my /opt directory in all the nodes. Now when I run the script from my current node I can set the path to python 2.7 interpreter from terminal but I am unable to manage it in the rest of the nodes where this script is getting distributed. I have added the shebang at the start of script like -
#!/opt/python2.7/bin/python
But its still not working. How can I change the python interpreter/python path at the beginning of the script itself.
What you explain should work but check:
that the script is executable (chmod +x my_script.py if required).
that you are calling the script directly and not using another Python interpreter (check that you execute ./my_script.py or /path/my_script.py and not python my_script.py).
To help to diagnose the problem you could add the following lines to the top of your script:
#!/opt/python2.7/bin/python
import sys
print(sys.executable)
if the output is not /opt/python2.7/bin/python you might be calling the script with another interpreter.
If for some reason you can only call scripts executed by the 2.6 version of Python remotely but you can also distribute additional files, you could try to send your main script somewhere and execute the following auxiliary script:
from subprocess import call
call("/opt/python2.7/bin/python /path/my_scipt.py", shell=True)
Whilst running python scripts from my linux terminal, I find myself typing in python myfile.py way too much. Is there a way on linux (or windows) to execute a python script by just entering in the name of the script, as is possible with bash/sh? like ./script.py?
At the top of the script, put
#!/usr/bin/python
or whatever the path to Python is on your computer (the result of which python on Linux). This tells the system to run your script using python. You'll also need to do chmod +x script.py for it to work.
Or if you're really lazy, use alias p=python or something.
you will need to chmod 0755 script.py and as a first line in script have something like
#!/usr/bin/python
The first line of your Python script should be:
#!/usr/bin/env python
or
#!/usr/bin/env python3
Depending on your version, and if Python 3 is your default or not.
Then, set executable bits at the shell (maybe with sudo if needed):
chmod +x my_script_name.py
Note that with the above done, you could rename your Python script
mv my_script_name.py my_script_name
and then execute your Python script just by:
my_script_name
at the shell line.
I have installed the new python release and would like to run .py files from the terminal.
How is this done from the terminal? I dont want to include the path in each command to run a .py file.
If you want to override the python command, you can set your PATH variable correctly, e.g. in your ~/.bash_profile:
export PATH=/path/to/python/:$PATH
That said, for managing different versions of components that are also provided by Mac OS X, I suggest to use a package manager such as Homebrew.
if you add a shebang at the start of the python file then you can run a python file by just its name from terminal
add #!/usr/bin/python
for mac(others add your respective path for python)
at the top of your python program and from your terminal you can run it just by filename(if it has executable permissions).
Have a look at the Python package under Applications. There is a shell script there called Update Shell Profile.command
Run this and it should set your path up properly.
Unless you mark you script as executable with chmod +x, you'll need to run python over it first. e.g. `python myscript.py'
I installed all of my python through macports, which has pros and cons. One of the benefits is that you don't have to worry about stuff like this, it just works. You can install python 2.6 and python 2.7 (and others), and then use the python_select utility to set up which python is run when you call "python blah.py"
Since you have installed a working python, the easiest way to run python files from the terminal is to cd your terminal to the directory where the file is located and then just type python my_code.py in the terminal.
