IndentationError: unindent does not match any outer indentation level

Question

When I compile the Python code below, I get

IndentationError: unindent does not match any outer indentation level

---

Answer 1

For example:

1. def convert_distance(miles):
2.   km = miles * 1.6
3.   return km

In this code same situation occurred for me. Just delete the previous indent spaces of line 2 and 3, and then either use tab or space. Never use both. Give proper indentation while writing code in python. For Spyder goto Source > Fix Indentation. Same goes to VC Code and sublime text or any other editor. Fix the indentation.
