Python – Time Strings to Seconds in Tuple List
• Last Updated : 02 Sep, 2020

Given Minutes Strings, convert to total seconds in tuple list.

Input : test_list = [(“5:12”, “9:45”), (“12:34”, ), (“10:40”, )]
Output : [(312, 585), (754, ), (640, )]
Explanation : 5 * 60 + 12 = 312 for 5:12.

Input : test_list = [(“5:12”, “9:45”)]
Output : [(312, 585)]
Explanation : 5 * 60 + 12 = 312 for 5:12.

Method : Using loop + split()

In this, we separate the minute and second components using split() and perform mathematical computation to convert the value to required seconds, strings converted to integers using int().

Output
```The original list is : [('5:12', '9:45'), ('12:34', '4:50'), ('10:40', )]
The corresponding seconds : [(312, 585), (754, 290), (640, )]
