I am new in python.

>>>li=["a","b","c"]
>>>li.reverse() 
>>>li
 ['c', 'b', 'a']

How we got an idea that we have to call function like this li.reverse() not like this reverse(li). Similarly on other function

sorted(li,reverse=True)
['c', 'b', 'a']

Here Why we can't call it li.sorted(reverse=True)?

Because `reverse` is a method of list data-structure, while `sorted` is a builtin method (Not specific to any module or data-structure). You need to consult python official documentation to locate the right method and its correct usage. – Sohaib Farooqi Dec 03 '17 at 12:40
