[python] How to execute python file in linux

I am using linux mint, and to run a python file I have to type in the terminal: python [file path], so is there way to make the file executable, and make it run the python command automatically when I doublr click it?

And since I stopped dealing with windows ages ago, I wonder if the .py files there are also automatically executable or do I need some steps.

Thanks

This question is related to python linux

The answer is


yes there is. add

#!/usr/bin/env python

to the beginning of the file and do

chmod u+rx <file>

assuming your user owns the file, otherwise maybe adjust the group or world permissions.

.py files under windows are associated with python as the program to run when opening them just like MS word is run when opening a .docx for example.


1.save your file name as hey.py with the below given hello world script

#! /usr/bin/python
print('Hello, world!')

2.open the terminal in that directory

$ python hey.py

or if you are using python3 then

$ python3 hey.py


Add to top of the code,

#!/usr/bin/python

Then, run the following command on the terminal,

chmod +x yourScriptFile

If you have python 3 installed then add this line to the top of the file:

 #!/usr/bin/env python3

You should also check the file have the right to be execute. chmod +x file.py

I suggest that you add

#!/usr/bin/env python

instead of #!/usr/bin/python at the top of the file. The reason for this is that the python installation may be in different folders in different distros or different computers. By using env you make sure that the system finds python and delegates the script's execution to it.

As said before to make the script executable, something like:

chmod u+x name_of_script.py

should do.


Add this at the top of your file:

#!/usr/bin/python

This is a shebang. You can read more about it on Wikipedia.

After that, you must make the file executable via

chmod +x your_script.py
