Video Length Conversion

Video Length in Seconds

Challenge Difficulty: Easy | Estimated completion time: ~10 minutes

You are given the length of a video in minutes. The format is mm:ss (ex: "02:54").

Create a function that takes the video length and return it in seconds.

Examples

minutesToSeconds("01:00") = 60
 
minutesToSeconds("13:56") = 836
 
minutesToSeconds("10:60") = -1
 
minuteToSeconds("121:49") = 7309

Notes

• The video length is given as a string.
• If the number of seconds is 60 or over, return -1 (see example #3).
• You may get a number of minutes over 99 (e.g. "121:49" is perfectly valid).

Solution

Python

def minutes_to_seconds(time: str) -> int: """Convert video length from mm:ss format to seconds. Args: time: Time string in mm:ss format Returns: Total seconds, or -1 if seconds >= 60 """ minutes, seconds = map(int, time.split(":")) if seconds >= 60: return -1 return minutes * 60 + seconds if __name__ == "__main__": print(minutes_to_seconds("01:00")) # 60 print(minutes_to_seconds("13:56")) # 836 print(minutes_to_seconds("10:60")) # -1 print(minutes_to_seconds("121:49")) # 7309
