For Loops

For loops iterate over sequences like lists, strings, and ranges.

Basic For Loop

Iterating Over Strings

Exercises

Using range()

Enumerate

Get both index and value:

Nested Loops

Loop with Accumulator

Zip - Iterate Multiple Lists

Practice Playground

Key Takeaways

• for item in sequence: iterates over each item
• range(n) generates 0 to n-1
• range(start, stop, step) for custom ranges
• enumerate() gives index and value
• zip() iterates multiple sequences together
• Use accumulator pattern for totals
