声称使用点表示法（例如.sort（））的Python方法在字符串以外的其他类型上不起作用吗？

Question

When i was studying Python course of Codecademy, they said 'Methods that use dot notation only work with strings', so... Is .sort() method only working in String type?, or Can it sort with other types? (int, float, etc)

Answer 1

Why didn't you quickly try it yourself?

>>> l = ['c', 'b', 'a']        
>>> l.sort()
>>> l
['a', 'b', 'c']
>>> l = [3, 2, 1]
>>> l.sort()
>>> l
[1, 2, 3]
>>> 

Answer 2

Actually string or string type can't be sorted using sort() . For example if you choose to do like the following

name = "hello"
print name.sort()

then it'll throw an error.But still if you really like to sort string or string types then try using sorted() as shown below.

name = "hello"
print sorted(name)

output:

['e', 'h', 'l', 'l', 'o']

Note: Upper case letters take the precedence over the lower case letters while sorting.
