tuple结构

tuple1=('name','when','hefei',123,456)
tuple2='name','when','hefei',123,456
tuple3=() # 空元组
tuple4=(123,) # 元组中只包含一个元素时，需要在元素后面添加逗号

print(tuple1[1]) # 访问元组
print(tuple2[0])
print(tuple1)

list1=[123,456] # 通过修改list元素变向修改tuple
tuple1=(' ',list1)
print(tuple1)
list1[0]=789
list1[1]=100
print(tuple1)

del tuple1 # 删除整个元组

tuple1 = (1, 2, 3) + (3, 4, 5)  # 连接
print(tuple1)
sign = 3 in tuple1  # 判断给定元素是否在元组中
print(sign)
for i in tuple1:  # 迭代输出
    print(i)
tuple1 = ('Hi!') * 4  # 重复连接
print(tuple1)

tuple1 = (1, 2, 3) + (3, 4, 5) 
print(len(tuple1))  # 输出元组元素个数
print(max(tuple1))  # 元组字典序最大元素
print(min(tuple1))
tuple1 = tuple(list1) # 将列表转换为元组
print(tuple1)
