When you execute Python code, you will often see an pyc file with the same name automatically generated in the same directory. This is the Python source code after the compiled bytecode, generally in the code execution, automatically generate the referenced py file PYc

File. This file can be executed directly, open with a text editor and cannot see the source code.

3, Pyw

is another extension, the only difference with the PY is that under Windows double-clicking the pyw extension of the source code will call Pythonw.exe execute the source code, this way of execution will not have a command line window.

It is mainly used when the GUI program publishes without needing to see the console information.
