Python | Check if k occurs atleast n times in a list

Let's delve into a tutorial on this topic.

Problem Statement:

Given a list of numbers and two integers k and n, determine if the number k occurs at least n times in the list.

Example:

For the list lst = [1, 2, 3, 4, 1, 2, 1, 5], k = 1, and n = 3, the answer is True because the number 1 occurs 3 times in the list.

Steps:

  1. Use the count() method of the list to count occurrences of k.
  2. Compare the count to n and return the result.

Python Implementation:

def occurs_at_least_n_times(lst, k, n): return lst.count(k) >= n # Example usage: lst = [1, 2, 3, 4, 1, 2, 1, 5] k = 1 n = 3 print(occurs_at_least_n_times(lst, k, n)) # Outputs: True

Explanation:

  • The count() method of a list returns the number of times a specific value (k in our case) appears in the list.

  • We then compare this count to the given number n to determine if k occurs at least n times in the list.

This wraps up the tutorial on how to check if a number k occurs at least n times in a list using Python!
