Write a regular expression to find all the times in a string. Times will be in 24-hours format with hours and minutes and optionally seconds: hh:mm(:ss). Match only valid times.

Example

txt1 = "Breakfast at 09:00 in the room 123:456."
txt2 = "The incident took place last Wednesday at 00:56:41."
txt3 = "We will have two meetings: from 10:30 to 11:00 and from 11:45 to 11:75."
pattern = "yourregularexpressionhere"

re.findall(pattern, txt1) ➞ ["09:00"]
re.findall(pattern, txt2) ➞ ["00:56:41"]
re.findall(pattern, txt3) ➞ ["10:30", "11:00", "11:45"]

Notes

• You don't need to write a function, just the pattern.
• Do not remove import re from the code.
• Find more info on RegEx in Resources.
• If you're stuck, check Comments for some hints.
