如何从PyCharm导出一个Python程序

Question

I have a Python project created in PyCharm. Now that it's finished I want to make it available without PyCharm (making it an executable is not relevant). It consists of different packages and quite a few files inside each package. How can I export the project so I can run it from one file that will call the rest?

Answer 1

If you do not want to publish the project and just use it for yourself:

1. Create a new __main__.py in your project root directory and start your program from there (by importing the old main.py etc.)

2. Make sure the program runs as expected: Run python __main__.py [arguments] in the root directory.

3. If this works, zip the whole project directory using an archiver and use like this:

   python myproject.zip [arguments]

Answer 2

So the answer to your question is that it's complicated, but what you want to do is package your app and make it distributable. This means including the python interpreter in the app as well as all of its dependancies so that anyone can use it without first installing python or anything additional to your app.

BeeWare's Briefcase does the heavy lifting in packaging in this way:

Think of PyCharm as a notepad/gedit - text editor of sorts. You can simply save the file with any name and a .py extension.

Now, to make it interpretable by Python interpretor, do the following:

import math  # an example import
# other imports


class SomeClass:
    def __init__(self):
        self.x = None

def someFnc():
    pass

def starting_point():
    # Make sure your logic begins execution here
    # e.g. use someFnc() or SomeClass here

if __name__ == '__main__':
    starting_point()

Above template will make your .py file ready for interpretation. That is to say, on a shell/cmd you can write this:

$> python your_file.py
