Common Python Errors and How to Fix Them

Every Python programmer encounters errors. Here's how to fix the most common ones.

SyntaxError

❌ Error: Missing colon, parenthesis, or quotes

✅ Fix: Check syntax carefully. Python is sensitive to indentation and punctuation.

❌ Error: Inconsistent spacing

✅ Fix: Use 4 spaces consistently. Don't mix tabs and spaces.

❌ Error: Variable not defined

✅ Fix: Define variables before using them. Check for typos.

❌ Error: Wrong data type used

✅ Fix: Convert types using int(), str(), float(), etc.

❌ Error: List index out of range

✅ Fix: Check list length before accessing. Use len() function.
