Python uses the cTYPES module to call WindowsAPI to get the system version example

Python uses the cTYPES module to invoke the Windows API GetVersionEx get the current system version without using Python32

Copy the Code code as follows:

#!c:/python27/python.exe
#-*-Coding:utf-8-*-

"Judging the current system version by invoking the window API"
# demonstrates calling Windows API functions via cTYPES.
# The author already knows Python32 can achieve the same function
# Add a semicolon at the end of the statement, purely personal habits
# only partial version judgment, more detailed version judging recommendation system OSVERSIONINFOEX structure

Import cTYPES;
