However, re.match("hello", "And they said hello" ) will also return

The caret ^ means "At the beginning of the line" so 'And they said
hello' will not be matched by the regex pattern '^hello'.
The docs are pretty good on the module

Note: If you want to locate a match anywhere in string, use search()
instead.
