re.findall()

The .findall() method iterates over a string to find a subset of characters that match a specified pattern. It will return a list of every pattern match that occurs in a given string.

re.findall(<pattern>, string)

Where <pattern> can include any of the following:

• A string: Jane
• A character class code: /w, /s , /d
• A regex symbol: $, |, ^

There are optional arguments that include the following:

• A starting index value (pos): 3
• An index value to end the search (endpos): 40
• Flags: IGNORECASE, VERBOSE, DOTALL

Match all of the times in the string:

import re

movie_str = "the evening shows start at 7:00pm and 10:15pm"

matches = re.findall(r"([\d:,.]+)(am|pm)?", movie_str)
# Square brackets designate a custom character class
# Parentheses identify a group within the pattern

print(matches)

This will output the following:

[("7:00", "pm"), ("10:15", "pm")]
