Having issues with unindent error in python

Question

  def linear_probe(self, value, start_index):
    hashed_key = start_index % len(self.table)
    while self.table[hashed_key] is not None:
      hashed_key = (hashed_key + 1) % len(self.table)
    return hashed_key, value`enter code here`

Hi here is my code for linear_probe function that I'm using in a lab, however for some reason I keep getting the unindent does not match any outer indentation level. however from how I can see my tabbing looks good as well as there are no white spaces

Answer 1

You are most likely mixing tabs and spaces.

Please make sure your editor is always using spaces.

If possible, let your editor highlight tabs.

Answer 2

The code as posted has a 2-space indentation for the whole function. Remove 2 spaces from the front of each line and try again:

## <-- accidental indent?
  def linear_probe(self, value, start_index):
    hashed_key = start_index % len(self.table)
    while self.table[hashed_key] is not None:
      hashed_key = (hashed_key + 1) % len(self.table)
    return hashed_key, value`enter code here`
