list.sort() is emptying my list

[Dalton]

The sort() method of the list is not working. Instead it is emptying my list:

Code

>>> l = ['e', 'c', 'a']
>>> l = l.sort()
>>> print l
None

What is the problem?

[Telplate]

The sort() method sorts the list in place and returns None. That is, if you assign a variable to the result of the sort() method the variable will refer to None.

Try it like this:

Code

>>> l = ['e', 'c', 'a']
>>> l.sort()
>>> print l
['a', 'c', 'e']
