Python sorted function Ordering

Students are sorted by name, sorted by score

From operator Import Itemgetter
students=[(' Bob ', ' Max '), (' David ', ' Dacheng '), (' A ', '), (' Maxie ', 94)]
Sorted (students,key=itemgetter (0))
Sorted (students, KEY=LAMBDA t:t[1])
#sorted (Students,key=itemgetter (1))

About the Itemgetter function: The Operator.itemgetter function does not get a value, but instead defines a function that acts on the object to get the value.

A = [A]
>>> B=operator.itemgetter (1)//define function B, get the value of the 1th field of an object
>>> B (a)
2
>>> B=operator.itemgetter (1,0)//define function B, get the 1th field and No. 0 value of an object
>>> B (a)
(2, 1)
