Duplicate Check Function

EasyPython

Problem

Write a function that checks for duplicate entries in a list.

Implement contains_duplicate(entries), which returns True if any value appears more than once and False otherwise. Assume all entries are hashable, and preserve no ordering because only the existence of a duplicate matters.

Function signature: def contains_duplicate(entries):

Input is a list of hashable values. The output is a Boolean.

Constraints

0 <= len(entries) <= 10^4
Every entry is hashable
Return a Boolean value

Function Signature

def contains_duplicate(entries):
