Introduction

A memo when the Python program [.py] is converted to an exe [.exe] to prevent it from being personalized. There are several ways to convert Python to an exe, but this time we will use PyInstaller, which can be easily done.

quick start

Reference: PyInstaller Quickstart

You can exe with pip and the following command without editing the source code. That's all, so it's very easy. If you just want to make it into an exe, this is fine. The latter half introduces how to write PyInstaller in Python code, so please refer to it if you are interested.

pip install pyinstaller
pyinstaller yourprogram.py

Option list

There are options that you can specify at run time. The frequently used options are summarized with reference to the following materials. Reference: [Using PyInstaller](https://pyinstaller.readthedocs.io/en/stable/usage.html https://gist.github.com/devlights/2ea169b60063d81f0526eceebeb7a8c6)

Generation options

option	function
-n, --name	Specifying the name of the generated file(default is the script name)
--specpath DIR	Specify generation folder(default is the current DIR)
-D,--onedir	Output all in one directory
-F,--onefile	Output in one file

OS-specific options

option	function
-w, --windowed, --noconsole	Hide the console
-i, --icon	Program icon[.ico extension]To set

General options

option	function
--clean, --noconsole	Clear PyInstaller cache and delete temporary files before building
-y, --noconfirm	Replace output directory without asking for confirmation
-v, --version	Display the version information of the program and exit

Other options

option	function
--exclude	Ignore the specified module or package. Can be used multiple times

Option usage example

pyinstaller yourprogram.py --exclude numpy,-v, -i data.icon

Run PyInstaller from Python code

Official document reference https://pyinstaller.readthedocs.io/en/stable/usage.html

`sample.py`


import PyInstaller.__main__

PyInstaller.__main__.run([
    '--name=%s' % package_name,
    '--onefile',
    '--windowed',
    '--add-binary=%s' % os.path.join('resource', 'path', '*.png'),
    '--add-data=%s' % os.path.join('resource', 'path', '*.txt'),
    '--icon=%s' % os.path.join('resource', 'path', 'icon.ico'),
    os.path.join('my_package', '__main__.py'),
])

Summary

It was a memo of PyInstaller that can make Python exe. It's convenient to be able to do it in two lines. However, there is one concern. If you refer to the following, it seems that there is a problem that the exe file is large and it takes a long time to execute. If the target you want to exe does not consider the processing speed, please try it. [Sad news] PyInstaller will spit out a 300MB exe file

Thank you for reading. If you have any concerns, please make an edit request or comment. If you like, please also LGTM.
