How to get a substring with variable indices

[=?KOI8-R?Q?=F3=D4=C1=CE=C9=D3=CC=C1=D7_=F1=C7=CC=C]

Hello all!

I have a string named text. I need to extract a substring from it
starting by variable 's' and ending by 'e'.

text[s:e] generates the following error:

TypeError: slice indices must be integers or None
How to be? :)

s and e both have to be integers or None. Try printing them out just
before your slice to see if their values are reasonable.

>>s = 2
e = 4
"python"[s:e]

'th'
