元組

>>> a = () #創建空元組

>>> print(a)

()

>>> b = (1,)

>>> print(b)

(1,)

>>> c = (1, 2, 4, 9, 20, 99) #創建元組

>>> d = (199, 888)

>>> e = (c + d) #元組拼接

>>> e

(1, 2, 4, 9, 20, 99, 199, 888)

>>> len(e) #計算元組元素個數

8

>>> max(e) #返回元組中元素最大值

888

>>> min(e) #返回元組中元素最小值

1

>>> e[2] #元組索引

4

>>> e[-2]

199

>>> e[1:] #元組截取

(2, 4, 9, 20, 99, 199, 888)

>>> f = [‘tianshi‘,‘buding‘,‘chun‘,‘xia‘]
