python程序中的.pyw文件

Answer 1

Python scripts (files with the extension .py) will be executed by python.exe by default. This executable opens a terminal, which stays open even if the program uses a GUI. If you do not want this to happen, use the extension .pyw which will cause the script to be executed by pythonw.exe by default (both executables are located in the top-level of your Python installation directory). This suppresses the terminal window on startup.

You can also make all .py scripts execute with pythonw.exe, setting this through the usual facilities, for example (might require administrative rights):

因此，在实践中，唯一的区别是一个保留控制台窗口，另一个则不保留。对于*.pyw，最明显的用法是使用GUI应用程序，因为具有独立GUI的应用程序显然不需要或不需要控制台窗口。

python.exe和pythonw.exe之间存在一些细微的实现差异，请参见https://stackoverflow.com/a/30313091/3703989
