What do I use on linux to make a python program executable

Question

I just installed a linux system (Kubuntu) and was wondering if there is a program to make python programs executable for linux.

Answer 1

Another way to do it could be by creating an alias. For example in terminal write:

alias printhello='python /home/hello_world.py'

Writing printhello will run hello_world.py, but this is only temporary. To make aliases permanent, you have to add them to bashrc, you can edit it by writing this in the terminal:

gedit ~/.bashrc

Answer 2

If one want to make executable hello.py

first find the path where python is in your os with : which python

it usually resides under "/usr/bin/python" folder.

at the very first line of hello.py one should add : #!/usr/bin/python

then through linux command chmod

one should just make it executable like : chmod +x hello.py

and execute with ./hello.py

Answer 3

Putting these lines at the starting of the code will tell your operating systems to look up the binary program needed for the execution of the python script i.e it is the python interpreter.

So it depends on your operating system where it keeps the python interpreter. As I have Ubuntu as operating system it keeps the python interpreter in /usr/bin/python so I have to write this line at the starting of my python script;

#!/usr/bin/python

After completing and saving your code

1. Start your command terminal

2. Make sure the script lies in your present working directory

3. Type chmod +x script_name.py

4. 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

Answer 4

You can use PyInstaller. It generates a build dist so you can execute it as a single "binary" file.

Python 3 has the native option of create a build dist also:

Answer 5

I do the following:

1. put #! /usr/bin/env python3 at top of script
2. chmod u+x file.py
3. Change .py to .command in file name

This essentially turns the file into a bash executable. When you double-click it, it should run. This works in Unix-based systems.

Answer 6

Just put this in the first line of your script :

#!/usr/bin/env python

Make the file executable with

chmod +x myfile.py

Execute with

./myfile.py
