Python pee tuples

#元组的声明

A = (1,2,3,4) #第一种
Print type (a)
<type ' tuple ' >

A = 1,2,3,4 #第二种
Print type (a)
<type ' tuple ' >

#元组的基本操作 Find, slice, sum "tuples are immutable sequences and do not support in-situ changes"

#查找

A = (1,2,3,4)
A[1]
OUT[13]: 2

#切片

A = (1,2,3,4)
A[:3]
OUT[14]: (1, 2, 3)

#求和

A =
b = 4,5,6
A+b
OUT[15]: (1, 2, 3, 4, 5, 6)

#利用元组多个的赋值 is easy to list such as:

A,b,c = A
Print A,b,c
1 2 3

#元组也可以当序列循环使用

A =
For I in A:
Print I

1
2
3
