Python3 元组
元组运算符
|
len((1, 2, 3)) |
3 |
计算元素个数 |
|
(1, 2, 3) + (4, 5, 6) |
(1, 2, 3, 4, 5, 6) |
连接 |
|
('Hi!',) * 4 |
('Hi!', 'Hi!', 'Hi!', 'Hi!') |
复制 |
|
3 in (1, 2, 3) |
True |
元素是否存在 |
|
for x in (1, 2, 3): print x, |
1 2 3 |
迭代 |
元组索引，截取
|
L[2] |
'Runoob!' |
读取第三个元素 |
|
L[-2] |
'Taobao' |
反向读取；读取倒数第二个元素 |
|
L[1:] |
('Taobao', 'Runoob!') |
截取元素，从第二个开始后的所有元素。 |
元组内置函数
|
1 |
len(tuple) |
>>> tuple1 = ('Google', 'Runoob', 'Taobao') >>> len(tuple1) 3 >>> |
|
2 |
max(tuple) |
>>> tuple2 = ('5', '4', '8') >>> max(tuple2) '8' >>> |
|
3 |
min(tuple) |
>>> tuple2 = ('5', '4', '8') >>> min(tuple2) '4' >>> |
|
4 |
tuple(seq) |
>>> list1= ['Google', 'Taobao', 'Runoob', >>> tuple1=tuple(list1) >>> tuple1 ('Google', 'Taobao', 'Runoob', 'Baidu') |
