IndentationError: unexpected indent

An IndentationError: unexpected indent in Python usually means that there’s an issue with inconsistent indentation. Here’s how you can fix it:

Common Causes and Fixes

1. Mixing Spaces and Tabs
   • Python enforces consistent indentation (use 4 spaces per indent).
   • Avoid mixing tabs and spaces.
   • Fix: Convert tabs to spaces in your editor.
   def example(): print("Hello") # 4 spaces
2. Accidental Extra Indentation
   • Check if there’s an extra space before a statement.
   ❌ Incorrect: print("Hello") # Extra space at the beginning ✅ Correct: print("Hello") # No extra indentation
3. Incorrect Indentation in Blocks
   • Make sure all lines inside a block are properly indented.
   ❌ Incorrect: def my_function(): print("Hello") print("World") # Misaligned indentation ✅ Correct: def my_function(): print("Hello") print("World") # Aligned properly
4. Unexpected Indentation Outside a Block
   • Ensure there’s no unnecessary indentation before standalone statements.
   ❌ Incorrect: x = 10 # This should not be indented ✅ Correct: x = 10 # Properly aligned

How to Fix in an Editor

• VS Code: Press Ctrl + Shift + P → Select “Convert Indentation to Spaces”.
• PyCharm: Go to Code → Reformat Code.
• Notepad++: Use Edit → Blank Operations → Tab to Space.
