How to store digits before and after decimal point, in different variables. PYTHON

The purpose of my code is to separate the digits before, and after my code.

for x in NumberStr:
        if x == '.':
            DigitsBeforeDP = NumberStr[:(x-1)]
            DigitsAfterDP = NumberStr[(x+1):]

This is the code I've written, and I have no idea why I get the error:

Traceback (most recent call last):
  File "...", line 101, in 
    ConvertToText()
  File "...", line 97, in ConvertToText
    DigitsBeforeDP = NumberStr[:(x-1)]
TypeError: unsupported operand type(s) for -: 'str' and 'int'

It might have something to do with the fact the NumberStr is stored as a string? Can anyone explain what I have done wrong, and tell me how to improve my code.

You can do this with the str.split() method.

before, after = number_str.split('.')

Also, the reason you were getting that error is because you were doing (x-1) but at that point in time x is a string, '.', so you are telling the interpreter to do ('.' - 1), which is why it tells you it does not support - for str and int.

You probably meant to have (NumberStr.indexOf(x) - 1)
