Python List Membership Testing: A Performance Comparison

The simplest and often the most efficient way to check for value existence in a Python list is to use the in operator: ... If you need to check for multiple values or perform frequent membership checks, converting the list to a set can significantly improve performance. Sets have efficient lookup times, typically O(1).

Python Membership Operators: Master 'in' and 'not in'

When working with membership operators, it’s essential to consider performance implications: For lists and tuples, the in operator performs a linear search, which can be slow for large sequences.. Sets and dictionaries use hash tables, making membership tests much faster, especially for large datasets.. String membership tests are optimized in Python and are generally fast.
