编写 win_cef.py  如下

# Example of embedding CEF browser using PyWin32 library.
# Tested with pywin32 version 221 and CEF Python v57.0+.
#
# Usage:
#   python win_cef.py
#   python win_cef.py --multi-threaded
#
# By passing --multi-threaded arg CEF will run using multi threaded
# message loop which has best performance on Windows. However there
# is one issue with it on exit, see "Known issues" below. See also
# docs/Tutorial.md and the "Message loop" section.
#
# Known issues:
# - Crash on exit with multi threaded message loop (Issue #380)from cefpython3 import cefpython as cefimport distutils.sysconfig
