5 Python Built-ins You’re Not Using (But Should Be)

This article introduces five underused Python built-ins that experienced developers rely on daily.

• •zip() lets you iterate over multiple lists simultaneously and can combine them into a dictionary
• •any() and all() check conditions across iterables without explicit loops, and short-circuit for efficiency
• •enumerate() provides both index and value during iteration, replacing the verbose range(len()) pattern
• •map() applies a function to every item in a list, suitable for simple single-function transformations
• •The collections module offers Counter for frequency counting, defaultdict to avoid KeyErrors, and deque for fast double-ended queue operations
