Getting one value from a python tuple

你可以写

i = 5 + Tup()[0]

元组可以像列表一样被索引。

The main difference between tuples and lists is that tuples are immutable - you can't set the elements of a tuple to different values, or add or remove elements like you can from a list. But other than that, in most situations, they work pretty much the same.

对于将来想要得到答案的人,我想对这个问题给出一个更清楚的答案。

# for making a tuple

MyTuple = (89,32)
MyTupleWithMoreValues = (1,2,3,4,5,6)

# to concatinate tuples
AnotherTuple = MyTuple + MyTupleWithMoreValues
print AnotherTuple

# it should print 89,32,1,2,3,4,5,6

# getting a value from a tuple is similar to a list
firstVal = MyTuple[0]
secondVal = MyTuple[1]

# if you have a function called MyTupleFun that returns a tuple,
# you might want to do this
MyTupleFun()[0]
MyTupleFun()[1]

# or this
v1,v2 = MyTupleFun()

希望这能为某些人扫清障碍。
