Python - String String Replace
Introduction
To replace a substring, you can use the string replace method:
Demo
S = 'testmy' S = S.replace('mm', 'xx') # Replace all mm with xx in S print( S )
Result
The replace method takes as arguments the original substring and the string to replace it with:
Demo
print( 'aa$bb$cc$dd'.replace('$', 'TEST') )
Result
You can use replace with a third argument to limit it to a single substitution:
Demo
S = 'xxxxTESTxxxxTESTxxxx' print( S.replace('TEST', 'EGGS') ) # Replace all print( S.replace('TEST', 'EGGS', 1) ) # Replace one # from w ww .jav a 2s . c o m
Result
