def find(str, ch, start=0):

  index = start

  while index < len(str):

    if str[index] == ch:

      return index

    index = index + 1

  return -1

Add a fourth parameter, end, that specifies where to stop looking. The default value of end should be len(str).

Symta:



find Str Ch Start=0 End=0

 -> cut Start End Str | ([I++_ !Ch @_]->I) |> Start+It :: ~1

Python:



def find(str, ch, start=0, end=None):

  index = start

  if end is None:

    end = len(str)

  while index < len(str):

    if index > end:

      break

    if str[index] == ch:

      return index

    index = index + 1

  return -1
