Python loops practice
Python loops practice for learners who need iteration to feel natural.
Loops become easier when you solve several similar problems in a row. This hub starts with public preview exercises, then points to the full curriculum for more loop patterns without sending locked lessons through login redirects.
Core skill
Repeat work over lists, strings, and ranges
Best start
For loops with visible input and output
Common patterns
Counting, totals, search, and skipping values
Safe links

Practice focus
Loop practice should make the moving parts visible.
A loop has three jobs: choose what to iterate over, decide what changes each round, and return or print the result in the exact shape the prompt asks for. Most beginner mistakes come from mixing those jobs together too early.
Use the exercises below in order. Start with visiting each item, then keep a count or total, then search for one matching value. Once that feels stable, move into enumerate, range, filtering, and harder string traversal.

Loop exercises to solve next
The public preview links open directly. Full-curriculum exercises are listed here for topic coverage but link to the curriculum page until public teaser pages exist.
For loops
Print List Items
Visit each list value in order and produce predictable output.
Accumulation
Sum List Numbers
Keep a running total while a loop walks through numeric values.
Counting
Count List Elements
Track how many items your loop has processed.
State in loops
Compute Running Total
Return every intermediate total instead of only the final answer.
Loop search
Find First Negative
Stop once the loop finds the first value matching a condition.
Enumerate
Index and Value With Enumerate
Use both position and value without manually managing a counter.
Practice routine
A simple loop routine
- 1. Name the collection before writing the loop.
- 2. Write the loop body for one item first.
- 3. Track one piece of state at a time: count, total, best value, or match.
- 4. Run the visible tests before adding shortcuts or extra conditions.
