Python元组方法总结

1.元组元素不可被修改，不可被增加或者被删除

2.为了以示区别，一般在创建元组的时候在尾部加个,

 tu = (111,"leslie",(1,2),True,[2,3],)

3.元组可用方法：count，index

4.元组的一级元素不能被修改

 

tu = (111, "leslie", (1, 2), True, [2, 3],)
# 索引
v = tu[0]
print(v)
# 切片
v = tu[0:2]
print(v)
# 可以被for循环，可迭代对象
for item in tu:
    print(item)

s="1a3qfr"
li = ["ad",23]
#字符串，元组，列表可以相互转化
v = tuple(s)
print(v)

v = tuple(li)
print(v)

v = list(tu)
print(v)

tu1 = ("wew","few")
v = "-".join(tu1)
print(v)

结果为
111
(111, 'leslie')
111
leslie
(1, 2)
True
[2, 3]
('1', 'a', '3', 'q', 'f', 'r')
('ad', 23)
[111, 'leslie', (1, 2), True, [2, 3]]
