count- number of time an element is present in a list.sort- to sort the data with in the list. Data in the list will be sorted in-place.
s ='asdfasfsafljojlsdfaljfasf'
l = list(s)
l.count?
Docstring: L.count(value) -> integer -- return number of occurrences of value
Type: builtin_function_or_method
l.count('a')
5
l.count('z')
0
l.sort?
Docstring: L.sort(key=None, reverse=False) -> None -- stable sort *IN PLACE*
Type: builtin_function_or_method
l.sort()
