如:
>>> print ord('a')
97
>>> print chr(97)
a
下面我们可以开始来设计我们的大小写转换的程序了:

复制代码 代码如下:

#!/usr/bin/env python
#coding=utf-8

def UCaseChar(ch):
if ord(ch) in range(97, 122):
return chr(ord(ch) - 32)
return ch

def LCaseChar(ch):
if ord(ch) in range(65, 91):
return chr(ord(ch) + 32)
return ch

def UCase(str):
return ''.join(map(UCaseChar, str))

def LCase(str):
return ''.join(map(LCaseChar, str))

print LCase('ABC我abc')
print UCase('ABC我abc')
输出结果:
abc我abc
ABC我ABC
