How to use the re.search() function to search for a pattern in a string?

While the previous search results are informative, I can provide an answer to the suggested question for completeness.

To use the re.search() function in Python to search for a regex pattern in a string, you can pass the pattern as the first argument to re.search(), and the target string as the second argument. For example:

import re

pattern = r'\d+'  # regex pattern to match one or more digits
text = 'I have 3 apples and 2 oranges'
match = re.search(pattern, text)

if match:
  print(match.group())  # Output: '3'

This will return the first non-overlapping occurrence of the regex pattern in the given string. In this case, the regex pattern \d+ matches one or more digits in the text, so the output will be '3'. If the pattern is not found in the string, re.search() will return None.
