一 概念:
元组是有序且不可更改的集合。在 Python 中,元组是用圆括号编写的。
二 使用方法:
1 基本创建:
thistuple = ("apple", "banana", "cherry") print(thistuple)
2 访问:
thistuple = ("apple", "banana", "cherry") print(thistuple[1])
三 遍历方法:
1 基本方法:
thetuple=(1,3,5,7,9) #first method print("first method:") for item in thetuple: print(item) #second method print("second method:") for value in iter(thetuple): print(value)
2 高级方法:
thetuple=(1,3,5,7,9) #method one print("first method:") for index in range(len(thetuple)): print("index:",index, "value:",thetuple[index]) #method two print("second method:") for index,value in enumerate(thetuple): print("index:",index, "value:",value)
