Question
Which of the following strings would Python return as matches to the regular expression pattern of \w? Select all that apply.
- "security"
- "2"
- "1B"
- "W"
Solution
The regular expression pattern "\w" matches any single alphanumeric character (letters and numbers). In Python, the "\w" pattern does not match whitespace or punctuation.
Given the strings you provided, Python would return matches for the following:
- "security" - This would return 's', 'e', 'c', 'u', 'r', 'i', 't', 'y' as separate matches because "\w" matches each alphanumeric character individually.
- "2" - This would return '2' as a match.
- "1B" - This would return '1' and 'B' as separate matches.
- "W" - This would return 'W' as a match.
So, all the provided strings have matches.
