Python string Replacement Methods: python string

Replacement of python strings is a problem that is often encountered when python operates on strings. Here we will briefly introduce the replacement method of strings.

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

Copy codeThe Code is as follows:
A. replace ('word', 'python ')

The output is hello python.

2. replace with a regular expression:

Copy codeThe 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.
