How do I check if there are duplicates in a flat list?
duplicates, list, python, string
Solution
Use `set()` to remove duplicates if all values are hashable:
>>> your_list = ['one', 'two', 'one']
>>> len(your_list) != len(set(your_list))
True
Problem
For example, given the list `['one', 'two', 'one']`, the algorithm should return `True`, whereas given `['one', 'two', 'three']` it should return `False`.
