Matching string from a file

[deanhystad]

If you want to be really picky.

with open("test.txt", "r") as file:
    for line in file:
        result = re.match(r"\s*(Start Time {1,2}(\d{1,2}/\d{1,2}/\d{4}) (\d{1,2}:\d{1,2}:\d{1,2} [AP]M))\s*$", line)
        if result:
            print(result.groups())

match() forces pattern to start at the start of line.
r"" makes the pattern a raw string. Don't have to worry about escape sequences.
\s* matches any number of whitespace characters.
() creates groups. This pattern has a group for the "Start Time...PM" part, the date part and the time part.
Start Time matches Start Time.
{1,2} matches one or two spaces.
\d{1,2} matches 1 or 2 digits.
/ matches /.
: matches :.
[AP]M matches AM or PM.
\s*$ matches whitespace up to the end of the line.
