Pass \d+ into re.compile() in the pattern variable to designate that we want to grab as many digits as possible from the string.
Into re.match(), pass the pattern we just created, as well as the time_string we want to extract from.
Use lambda within the apply() method to perform the extraction.
Print out the head() of both the length_of_time and minutes columns to compare.
