How to use a regular expression match a whole word with Python?
To use a regular expression match a whole word with Python, we can use the re.search method with a regex to match a whole word.
For instance, we write:
import re
x = "this is a sample"
res = re.search(r'\bis\b', x)
print(res)
We call re.search with a regex that matches the word ‘is’.
\b indicates the word boundary.
The 2nd argument is the string that we’re searching for the matches for.
Therefore, res is <re.Match object; span=(5, 7), match='is'>.
