Python exercises: 165+ practice problems with solutions

Beginner Python exercises

If you just started, work through Basic Python Programs first: variables, I/O, basic math, and simple logic. The goal is muscle memory, not clever one-liners.

What you will practice: printing output, variables, arithmetic, type conversion, input.

Sample problems

• Swap two variables without a third variable.
• Simple calculator: two numbers and an operator (+, −, ×, ÷).
• Celsius to Fahrenheit using F = (C × 9/5) + 32.

Python conditional exercises

Branching and edge cases. Practice if / elif / else, comparisons, and logical operators.

• FizzBuzz from 1–50 (multiples of 3 / 5 / both).
• Largest of three numbers without max().
• Letter grade from a 0–100 score.

Python loop exercises

for, while, nested loops, range(), patterns, and accumulation.

• Sum of digits of a positive integer.
• Multiplication table for a user-entered number.
• Reverse digits without string conversion.
• Star / number patterns with nested loops.

Python string exercises

Slicing, methods, formatting, palindromes, anagrams, and character counting.

• Reverse a string without the [::-1] shortcut.
• Count vowels (case-insensitive).
• Palindrome check ignoring spaces and case.
• Anagram check for two strings.

Python list exercises

Indexing, methods, comprehensions, search, nested lists, and rotations.

• Remove duplicates while preserving order.
• Second largest without sort() or max().
• Flatten a nested list.
• Rotate a list to the right by k positions.

Python OOP exercises

Classes, __init__, methods, inheritance, encapsulation, and modeling real entities.

• Bank account with deposit, withdraw, and non-negative balance.
• Student grade book with average / min / max.
• Shape hierarchy with area() on subclasses.
• Employee and manager with team membership.

Python file handling exercises

open(), read/write/append, line iteration, and simple CSV-style processing.

• Word count from a text file.
• Reverse line order into a new file.
• Find-and-replace across a file.
• Top score from a CSV of names and scores.

Python exercises by difficulty

• Just started (weeks 1–2): Basic → Conditionals → Loops.
• Comfortable with basics: Strings and lists — high leverage for interviews and apps.
• Ready for serious projects: OOP and file handling.
