How can I export my spotipy code efficiently?

I wrote a python program using the spotipy library. I used pyinstaller to create executables and it works fine for me. However, when I try to email it to someone (via gmail, sent through imessage) it doesn't run correctly. We are all on Mac OS X. When they try to open it with terminal, it opens terminal but the program doesn't run. I created the executable with the following command:
pyinstall -F example.py
and I sent the executable in the dist folder. I've never really tried to distribute any code before so any help would be appreciated. Thanks.

For XOS and if you gonna use pyinstaller:
pyinstaller
Put this line at the top of your python code and it will inform your operating systems to look up the binary program which needs for the execution of the python script for example it is the python interpreter.
Therefore it depends on your operating system where it keeps the python interpreter. If you have Ubuntu as operating system it keeps the python interpreter in /usr/bin/python so you have to write this line at the starting of your python script;
#!/usr/bin/python
Write above line at the top of your python code
Saving your code
Start your command terminal
Make sure the script lies in your present working directory
Type chmod +x script_name.py
Now you can start the script by clicking the script. An alert box will appear; press "Run" or "Run in Terminal" in the alert box;
Or, at the terminal prompt, type ./script_name.py
For Windows as your OS.
Make sure the python script contains:
if __name__ == '__main__':
main()
Make sure you do not have a folder with the same name as the script you are trying to turn into an executable.
Make sure you do not have any .ipynb in the same folder where you will create your executable, it will not run properly.
You can follow these instructions:

Python 3 install error. This file does not have a program associated

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.

Python 3.6.0 can't be installed on Ubuntu 16.04?

I wrote a script on my Windows machine using python 3.6.0. I wanted to run it on Linux machines as well so I transferred the .py script onto my Ubuntu VM. The problem is, I tried to install python 3.6.0 in every way possible but it doesn't really work. Python3 works when I want to execute a .py file, but since I am trying to use pyisntaller to convert it into an executable for linux, I need the default version as 3.6.0. python --version gives me Python 2.7.2. How can I fix this so when I do python --version it shows 3.6.0?

There is no point in changing your default python version, Ubuntu relies heavily on older versions of python. And what do you mean by convert it into an executable for Linux? Almost every file on your file system is an executable. If you want to make your program run as a command in the terminal you can do this though:
text_editor_of_your_choice .bashrc
This should open the hidden .bashrc file, and scroll to the bottom of it. Below is what the file looks like...
.bashrc
After that you can create a function for the python command you want to run.
eg. function ghst {python3.6 /home/user/example_script/example.py $#}
Start a terminal session and then try running it. Now that's if you want to run it inside the terminal. If it you want to create this "executable file" you speak of you can create a simple shell script.
First go in the terminal and run touch file_name_of_your_choice.sh
This will create a blank file named file_name_of_your_choice with the file extension "sh". After that open the text file in whatever directory you created it in, if you are unsure do pwd.
In your first line make sure that the user is inside the directory of the .py file by doing
cd /home/user/folder/ On the next line you should then execute the .py file. You can do this by typing this: python3 file.py. This will execute the program inside a terminal window. After you have done all of this make sure that the python file and the script file are executable. Do this by doing chmod +x file.py and chmod file.sh.
This is what the end result looks like
example script
You mentioned inside your question that you want your program to be able to run on Linux machines as well. Whether this is for personal or a public project of some sort it comes in handy by packaging all the required files in a .zip format this makes it easy to unpack everything when moving to separate machines. If there are any problems let me know.

How to create a executable file to a python program

I want to know if there are a way to create a executable file to a python program (in linux or windows).
Imagine a person that doesn't know how to open the terminal but want to use the program, I want to create a executable file which that person only have to click on it and the program opens.
thanks

I use the command
c:\pyinstaller\pyinstaller.py --onefile --console my_script.py
it works like a charm ;) (note only applies to windows) ... if theyre using linux they should be really comfortable in a terminal

Well, there are many possibilities to both do what you ask and to answer your question.
The simplest answer would be thus: On windows, with a Python interpreter installed, it registers the .py, .pyc and .pyo file extensions to be opened using the told Python interpreter and thus you get a free "double-click-to-run" behavior.
On Linux, a similar behavior can be achieved by telling the loader which interpreter to use in order to run the script by adding the following line as the 1st line in the file:
#!/usr/bin/python -O
and marking it as an executable using chmod +x myfile.py.
This will allow a user to run your file with a double-click from whatever file explorer he uses.
As for other possibilities, there are quite a few solutions, I'd recommend you to run a google search for it.
For Windows I'd recommend py2exe, and I'm not familiar with Linux solutions, and, anyway it was discussed on StackOverflow here
Best of luck!

Python scripts stopped running on double-click in Windows

I always ran my scripts on windows by double-clicking them. However after I reinstalled my python versions this is not happenning. My python installations are on C:\Python27 and C:\Python33. PATH has C:\Python27\ in it. If I try to run a script from cmd, it works ok. But when I double-click any .py file nothing happens.
I am completely clueless as I don't use windows often for scripting.
What can be the reason for that?

Steps to cure this problem
1) Right click on your script.
2) Choose properties and then
3) Change the option how to open your script (set it as python).
This will make all of your .py extension scripts into running on double click in windows

Double-clicking is not related to PATH, but extension association.
Check register extension option when you install(or recover) the python.

Removed all python versions and folders. Installed WinPython-64bit-2.7.5.1 package (as before) and everything works now. I can run my scripts by double-clicking them. Really strange.

I was having the same issue. The code works in the IDLE but not on double click. I ran the script through the command prompt and it gave me an error that the IDLE didn't find. Windows didn't like the ascii characters I was printing. I removed them and the script started to work on double click again.
