The search method of the re module
The search method of the re module searches only for the first match with a regular expression. In the first parameter of the method, we specify the regular expression to search for, and in the second parameter, the string in which to search for it. In the third optional parameter, you can specify flags for additional regular expression settings. The method returns a Match object. If no matches are found, None is returned.
Syntax
import re
re.search(regular expression, string, [flags bunting])
Example
Let's find the first substring with numbers using the search method:
txt = 'aaa 123 bbb 456'
res = re.search('\d+', txt)
print(res)
Result of code execution:
<re.Match object; span=(4, 7), match='123'>
Example
Let's output a match from the Match object:
txt = 'aaaa 123 bbbb 456'
res = re.search('\d+', txt)
print(res[0])
Result of code execution:
'123'
