I want to use the optional parameters of the count method.

I don't know if the problem is a syntax problem.

str.count(sub[, start[, end]]) Return the number of non-overlapping occurrences of substring sub in the range [start, end]. Optional arguments start and end are interpreted as in slice notation.

I've tried: 1.

cadena = "supercalifragilisticoespialidoso"
print(cadena.count("l",[0,15]))

cadena = "supercalifragilisticoespialidoso"
print(cadena.count("l",[int(0),int(15)]))

cadena = "supercalifragilisticoespialidoso"
print(cadena.count("l",[0,[15]]))

Always, the error seems to be the same:

TypeError: slice indices must be integers or None or have an __index__ method

It's just `cadena.count("l", 0,15))`. – Daniel Roseman Aug 31 '19 at 11:29
I don’t have time to give a complete answer, but try cadena.count(“l”, 0,15). In short, the brackets mean the arguments are optional, not that they should be in brackets. – Patrick M Aug 31 '19 at 11:29
`print(cadena.count("l", 0, 15))` count the number of `i` between index 0 to 15. – ComplicatedPhenomenon Aug 31 '19 at 11:29
