Understanding Python Errors
When you run into errors, don't worry! They are a normal part of programming. Python provides helpful error messages that tell you:
- What type of error occurred
- Where the error happened
- What might have caused it
Common Python errors:
- SyntaxError: Something wrong with how you wrote the code
- IndentationError: Incorrect spacing in your code blocks
- TypeError: Using the wrong type of data
- NameError: Using a variable that doesn't exist
- ValueError: Using the right type but wrong value
Key Points:
- Errors help you learn
- Python provides clear error messages
- Most errors are easy to fix
- Understanding errors improves coding skills
