Python Tutor-visual Python code debugger

Example

Through interactive problem-solving exercises, Python Tutor helps users grasp complex concepts. For instance, users might be asked to write a program that calculates the sum of all numbers in a list, with step-by-step guidance provided as needed.

Scenario

A beginner trying to understand how loops work in Python can be guided through writing a loop that sums up a list of numbers, reinforcing their understanding of iteration and accumulation.

Example

When users encounter errors, Python Tutor can help diagnose and understand the problem. For example, if a user receives a 'syntax error' when trying to run their code, Python Tutor will prompt them to check specific lines and understand common pitfalls.

Scenario

A student working on a homework assignment might get stuck with a syntax error. Python Tutor will ask them questions about their code, helping them identify and fix the mistake, and explaining why the error occurred.

Example

Python Tutor provides exercises that reinforce key programming concepts. For example, after learning about conditional statements, users might be asked to write a program that determines whether a number is prime.

Scenario

After a lesson on conditionals, a user is given a challenge to write a function that checks if a year is a leap year. This task helps solidify their understanding by applying what they've learned in a practical scenario.
