Greedy vs Non-Greedy in Re - Good Example
Here is a good example to explain greedy vs, non-greedy search using module re in Python.
The '*', '+', and '?' qualifiers are all greedy; they match as much text as possible. Sometimes this behaviour isn't desired; if the RE is matched against 'title
', it will match the entire string, and not just ''. Adding '?' after the qualifier makes it perform the match in non-greedy or minimal fashion; as few characters as possible will be matched. Using .*? in the previous expression will match only '
'.
