本文实例讲述了基于wxpython开发的简单gui计算器。分享给大家供大家参考。具体如下：
# wxcalc1 a simple gui calculator using wxpython
# created with the boa constructor which generates all the gui components
# all i had to do is add some code for each button click event
# boa free from: http://boa-constructor.sourceforge.net/
# note that boa-constructor-0.3.1.win32.exe
# still uses wxpythonwin32-2.4.2.4-py23.exe
# but is expected to work with wxpython version 2.5 soon
# tested with python23 vegaseat 26feb2005
from wxpython.wx import *
# some boa generated global ids …
