Strict Professor-class cancellation in python.py

''' In a college ,  a professor is strict and mandates that at least M students out of the total N students must arrive on time to his class.Else he would cancel the class. The start time of the class is also passed as the input.The individual arrival time for N students is also passed as input in 24 hours format.

The program must print if the class was cancelled or not.

Example 1:

Input:
5 3
9:30
9:30 9:38 9:31 9:32 9:31
Output:
Yes
Explanation:
4 out of the students arrived late, which means only one arrived on time. As the professor has mandated 3 out of the 5 must arrive on time, the class was cancelled and hence Yes is printed as the output.
