Make a Runnable Script.https://realpython.com/lessons/python-maze-runnable-script/#t=0.67
In this section,https://realpython.com/lessons/python-maze-runnable-script/#t=2.531
you’ll provide a command-line interface to your Python package By usinghttps://realpython.com/lessons/python-maze-runnable-script/#t=4.11
argparse.https://realpython.com/lessons/python-maze-runnable-script/#t=8.28
It will take a path to a binary file with your maze as input.https://realpython.com/lessons/python-maze-runnable-script/#t=9.444
00:13https://realpython.com/lessons/python-maze-runnable-script/#t=13.25
Then it will try to find the maze’s solutions and render them in separate tabs inhttps://realpython.com/lessons/python-maze-runnable-script/#t=13.25
your web browser as scalable vector graphics.https://realpython.com/lessons/python-maze-runnable-script/#t=17.22
If it can’t find any solutions,https://realpython.com/lessons/python-maze-runnable-script/#t=20.169
then you’ll see an appropriate message in your console.https://realpython.com/lessons/python-maze-runnable-script/#t=22.33
00:27https://realpython.com/lessons/python-maze-runnable-script/#t=27.48
Add the __main__.py file to your project to turn it into a runnable Pythonhttps://realpython.com/lessons/python-maze-runnable-script/#t=27.48
package.https://realpython.com/lessons/python-maze-runnable-script/#t=31.82
This file should live inside your maze_solver package next to the emptyhttps://realpython.com/lessons/python-maze-runnable-script/#t=33.21
__init__.py file.https://realpython.com/lessons/python-maze-runnable-script/#t=37.28
00:41https://realpython.com/lessons/python-maze-runnable-script/#t=41.55
Its contents are seen on-screen.https://realpython.com/lessons/python-maze-runnable-script/#t=41.55
01:21https://realpython.com/lessons/python-maze-runnable-script/#t=81.85
The code finds,https://realpython.com/lessons/python-maze-runnable-script/#t=81.85
renders, and previews all the solutions of the loaded maze or prints an errorhttps://realpython.com/lessons/python-maze-runnable-script/#t=83.1
message.https://realpython.com/lessons/python-maze-runnable-script/#t=87.47
01:36https://realpython.com/lessons/python-maze-runnable-script/#t=96.72
It uses the argparse module to parse the file path,https://realpython.com/lessons/python-maze-runnable-script/#t=96.72
which is currently the only expected command-line argument.https://realpython.com/lessons/python-maze-runnable-script/#t=99.75
Later, you can add more if you want to—for example,https://realpython.com/lessons/python-maze-runnable-script/#t=107.89
to allow previewing mazes without a solution.https://realpython.com/lessons/python-maze-runnable-script/#t=111.1
01:54https://realpython.com/lessons/python-maze-runnable-script/#t=114.839
Finally,https://realpython.com/lessons/python-maze-runnable-script/#t=114.839
the file uses the name-main idiom to protect the main() function from running ifhttps://realpython.com/lessons/python-maze-runnable-script/#t=115.91
other modules import the package.https://realpython.com/lessons/python-maze-runnable-script/#t=120.57
If you want to know more about using argparse,https://realpython.com/lessons/python-maze-runnable-script/#t=126.85
then check out this Real Python course.https://realpython.com/lessons/python-maze-runnable-script/#t=129.02
02:14https://realpython.com/lessons/python-maze-runnable-script/#t=134.97
To run the package, use the command seen on-screen in your terminal.https://realpython.com/lessons/python-maze-runnable-script/#t=134.97
02:30https://realpython.com/lessons/python-maze-runnable-script/#t=150.23
Optionally, you can specify a shortcut in your pyproject.toml file.https://realpython.com/lessons/python-maze-runnable-script/#t=150.23
You can have as many custom commands as you like,https://realpython.com/lessons/python-maze-runnable-script/#t=160.46
which should map to specific functions in the given module within the project.https://realpython.com/lessons/python-maze-runnable-script/#t=162.69
02:51https://realpython.com/lessons/python-maze-runnable-script/#t=171.09
To register the new command in your virtual environment,https://realpython.com/lessons/python-maze-runnable-script/#t=171.09
you must install the package using pip once more.https://realpython.com/lessons/python-maze-runnable-script/#t=173.85
03:03https://realpython.com/lessons/python-maze-runnable-script/#t=183.25
Once you’ve reinstalled the package,https://realpython.com/lessons/python-maze-runnable-script/#t=183.25
you’ll be able to solve mazes using the solve command without explicitly callinghttps://realpython.com/lessons/python-maze-runnable-script/#t=184.76
on Python.https://realpython.com/lessons/python-maze-runnable-script/#t=188.92
03:16https://realpython.com/lessons/python-maze-runnable-script/#t=196.95
Note that you need to run it from your virtual environment.https://realpython.com/lessons/python-maze-runnable-script/#t=196.95
The solve command,https://realpython.com/lessons/python-maze-runnable-script/#t=199.461
which you just created, is not available outside of it.https://realpython.com/lessons/python-maze-runnable-script/#t=200.8
You now have a working command-line interface to your Python package and ahttps://realpython.com/lessons/python-maze-runnable-script/#t=208.44
working maze solver that you can access quickly from the command line orhttps://realpython.com/lessons/python-maze-runnable-script/#t=212.22
terminal.https://realpython.com/lessons/python-maze-runnable-script/#t=216.18
03:36https://realpython.com/lessons/python-maze-runnable-script/#t=216.639
While you’ve reached the end of this two-part course,https://realpython.com/lessons/python-maze-runnable-script/#t=216.639
remember that you can always keep improving the project.https://realpython.com/lessons/python-maze-runnable-script/#t=219.64
For example,https://realpython.com/lessons/python-maze-runnable-script/#t=222.604
you could add more command-line arguments to control the rendering process orhttps://realpython.com/lessons/python-maze-runnable-script/#t=223.7
provide an option to save the results as an image instead of previewing them inhttps://realpython.com/lessons/python-maze-runnable-script/#t=227.68
the browser.https://realpython.com/lessons/python-maze-runnable-script/#t=231.6
03:52https://realpython.com/lessons/python-maze-runnable-script/#t=232.341
The possibilities are endless, but in the next part of the course,https://realpython.com/lessons/python-maze-runnable-script/#t=232.341
you’ll look back at what you’ve learned.https://realpython.com/lessons/python-maze-runnable-script/#t=236.3
