Python character conversion _python

Such as:
>>> Print ord (' a ')
97
>>> Print Chr (97)
A
Here we can start to design our case conversion program:

Copy Code code as follows:

#!/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 i ABC ')
Print UCase (' ABC i ABC ')

Output results:
ABC i ABC
ABC i ABC
