An indentation error in Python occurs when the interpreter encounters an unexpected indentation level. Python uses indentation to define blocks, so every line that belongs to the same block must be indented by the same amount. Common causes include mixing tabs and spaces, inconsistent indentation levels, or accidentally adding or removing spaces. To fix it:
1. Enable visible whitespace in your editor to see tabs and spaces.
2. Convert all indentation to either spaces or tabs (PEP 8 recommends 4 spaces).
3. Ensure that all lines in a block have the same indentation level.
4. Use an IDE or linter that highlights indentation mismatches.
5. If you copy code from another source, re-indent the block manually.
After correcting the indentation, run the script again. If the error persists, check the line number indicated by the traceback and verify that the preceding block ends correctly (e.g., a missing colon after a function or loop header).
