Python string replacement

Python string replacementThis is a problem that is frequently encountered when operating strings in Python. Here we will briefly introduce the string replacement method.
Python string replacement can be implemented in two ways:
1 is the method of using the string itself.
2. Replace strings with regular expressions.

The following example is used for an experiment:
A = 'Hello word'
I replaced the word in string a with python.
1 use the replace method of the string itself
A. Replace ('word', 'python ')
The output is Hello python.

2. replace with a regular expression:
Import re
Strinfo = Re. Compile ('word ')
B = strinfo. sub ('python',)
Print B
The output is also hello python.
