yes, count(), capitalize(), and swapcase() are called methods.

The count() method counts the number of the given string in the object.

x = 'hello'
x.count('l')     ->  2
x.count('h')     ->  1

y = 'good morning'
y.count('o')     ->  3
y.count('oo')    ->  1

you can find out which methods belong to an object using the dir()
function and can get help for a method by using the help() function:

Help on built-in function swapcase:

swapcase(...)
	S.swapcase() ->  string
	    
    Return a copy of the string S with uppercase characters
    converted to lowercase and vice versa.
