Tracks Total Duration
Aufgabe
Swipe to start coding
Complete a function that calculates the total duration of all tracks in a list, converting the duration from milliseconds to minutes. Each track is represented as a dictionary containing various fields, including a duration_ms
field that indicates the track's duration in milliseconds.
Inputs:
tracks
: A list of dictionaries, where each dictionary represents a track and contains at least the following field:duration_ms
: An integer representing the duration of the track in milliseconds.
Steps:
-
Iterate Through Tracks:
- Loop through each track in the
tracks
list. - For each track, add its
duration_ms
value tototal_duration_ms
.
- Loop through each track in the
-
Convert to Minutes: After summing the durations in milliseconds, convert
total_duration_ms
to minutes by dividing it by 60,000 (since there are 60,000 milliseconds in a minute).
