Iteration Method

enumerate() - Index Tracking Made Easy

Get both index and value in loops without manual counting. Much more Pythonic than range(len(list))!

Why enumerate()?

Benefits over manual indexing

Pythonic: More readable than range(len(list))

Flexible: Custom start values for line numbers

Safe: No index-out-of-bounds errors

Efficient: Built-in C implementation
