Python Regex extract Minutes and Seconds-CodePudding

Given a string "Time Remaining: 2 min 25 sec", how do we use Python's re regex method to extract 2 and 25?

Tried the following but only managed to extract 2 but not 25.

import re

time_remaining = "Time Remaining: 2 min 25 sec"
pattern = "(?<=Time Remaining: )(.*)(?= min) (.*)(?= sec)"
matches = re.search(pattern, time_remaining)
if matches:
    print(matches.group(1))  # Obtained: "2"
    print(matches.group(2))  # Obtained: "min 25"
                             # Desired: "25"

CodePudding user response：

I would use re.findall here, with an actual pattern which matches the entire input:

time_remaining = "Time Remaining: 2 min 25 sec"
matches = re.findall(r'(\d ) min (\d ) sec\b', time_remaining)
print(matches)  # [('2', '25')]

The problem with your current pattern is that it uses zero width lookaheads to match the min and sec markers.
