Do A Case Insensitive RexEx Search In Python
Use the `re.IGNORECASE`` flag to do case insenstive searches. For example, here's the same search with and without it:
Code
=
=
Results
None
<re.Match object; span=(0, 4), match='TeSt'>
Notes
When doing a `.sub()`, the `flags` key should be called explicietly like:
re.sub('test', 'TeSt', 'source value', flags=re.IGNORECASE)
