[PROJECT] package python program into exe file

We can use the pyinstaller module to package python projects into exe files. The operation steps are as follows:

1. Installing the pyinstaller module
   Operate in pycharm: file - > setting - > Project: XXX - > project interpreter, and then click
   Just hit +.
2. Enter the following command at the Terminal of pycharm:
   pyinstaller -F xxxx.py
   [note] relevant parameters are as follows:
   – icon = icon path (pyinstaller -F --icon=my.ico XXXX.py)
   -F is packaged as an exe file
   -w use window, no console
   -c use the console without windows
   -D create a directory containing exe and other dependent files
3. In the dist directory of the project, you can see that the generated exe file can be used directly in the windows system.
   [note] the essence of exe file is to package python interpreter and program together, so that we do not need to execute the program.
   Whether the windows system has a python interpreter or not.
   [note] Currently, pyinstaller only supports Python 3.6. If you are Python 3.7, you may fail.
