This is a summary of my code:

# import whateverdef createFolder():#someCodevar1=Gdrive.createFolder(name)return var1 def main():#someCodevar2=createFolder()return var2if __name__ == "__main__":print main()

One way in which I managed to return a value to a bash variable was printing what was returned from main(). Another way is just printing the variable in any place of the script.

Is there any way to return it in a more pythonic way?

The script is called this way:

folder=$(python create_folder.py "string_as_arg")

A more pythonic way would be to avoid bash and write the whole lot in python.

You can't expect bash to have a pythonic way of getting values from another process - it's way is the bash way.

bash and python are running in different processes, and inter-process communication (IPC) must go via kernel. There are many IPC mechanisms, but bash does not support them all (shared memory, for example). The lowest common denominator here is bash, so you must use what bash supports, not what python has (python has everything).

Without shared memory, it is not a simple thing to write to variables of another process - let alone another language. Debuggers do it, but they are written specifically for the host language.

The mechanism you use from bash is to capture the stdout of the child process, so python must print. Under the covers this uses an anonymous pipe. You could use a named pipe (also known as a fifo) instead, which python would open as a normal file and write to it. But it wouldn't buy you much.
