Python Mentor-AI-powered Python tutor

Example

When a user asks how to open and read a file in Python, Python Mentor would not only explain the process but also provide a sample code snippet: ```python with open('example.txt', 'r') as file: content = file.read() print(content) ```

Scenario

A beginner Python developer is attempting to automate reading several text files. Python Mentor guides them through file handling in Python, enhancing their scripting skills and understanding of file I/O operations.

Example

If a user presents a fragment of code that raises a syntax error, Python Mentor can pinpoint the error, explain why it occurs, and suggest the correct syntax. For example, correcting the common mistake of using '=' instead of '==' in a conditional statement.

Scenario

A student is working on a Python project for a class and encounters a runtime error. Python Mentor helps them identify the issue in their loop constructs or conditional checks, improving their debugging skills and saving time.

Example

Python Mentor could provide advice on optimizing Python code, such as using list comprehensions instead of loops for efficiency: ```python # Instead of using a loop: squared_numbers = [] for number in range(10): squared_numbers.append(number*number) # Use a list comprehension: squared_numbers = [number*number for number in range(10)] ```

Scenario

An experienced programmer looking to refine their Python skills can learn advanced techniques and performance improvements, applicable in writing more efficient, readable, and Pythonic code.
