元组创建

tuple1 = (1, 2, 3, True, 'hello')
print(tuple1)
print(type(tuple1))
list1 = [1]
print(list1)
tuple2 = (1,) # 元组只有一个元素时，加一个逗号
print(tuple2)
print(type(tuple2))
tuple3 = ()
print(tuple3)
print(type(tuple3))
tuple4 = tuple() # tuple():类型转换
print(tuple4)
tuple5 = tuple('hello') # str-->tuplr
print(tuple5)
tuple6 = tuple([1, 2, 3, 4]) # list-->tuple
print(tuple6)
list1 = list(tuple6) # tuple-->lis
print(list1)
str1 = str(tuple6) #tauple-->str
print(str1)
print(type(str1))
print(str1[2]);

print('------------------------')

序列的通用操作

#索引
print(tuple1[-1])

切片

print(tuple1[::-1])

len

print(len(tuple6))
print(max(tuple6), min(tuple6))

del

del tuple5

print(tuple5)

+

print(tuple1 + tuple6)

*

print(tuple1 * 3)

in

print(1 in tuple1)

print(list1)
list1[2] = 5
print(list1)

tuple1[1] = 4

print(tuple1)

元组的常用方法

a = tuple1.count('hello')
print(a)
print(tuple1)
a = tuple1.index(2)
print(a)
print('--------------------------')

元组遍历

for i in tuple1:
print(i)

for index,value in enumerate(tuple1):
print(index,value)

for i in range(len(tuple1)):
print(i,tuple1[i])
