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'
Replace the word in string a with python

1. use the replace method of the string itself

The code is as follows:

A. replace ('word', 'Python ')

The output is hello python.

2. replace with a regular expression:

The code is as follows:

Import re
Strinfo = re. compile ('word ')
B = strinfo. sub ('Python',)
Print B

The output is also hello python.

If you use this method, it depends on your choice.
