Python Basic Tutorials summarize the list of elements and tuples

1. Sequence

Python contains 6 built-in sequences- lists, tuples, strings, Unicode strings, buffer objects, xrange objects

2. General sequence operation

2.1 Index

Note: input () transforms the corresponding type according to the user input, and if you want to enter characters and strings, you must enclose them in quotation marks.

Raw_input () is converted into a character type regardless of the type of user input.

2.2 Shards

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

(1) numbers[:]

[1, 2, 3, 4, 5, 6, 7, 8, 9, ten] #整个列表

(2) Numbers[3:5]

[4, 5] #包括起始索引对应的元素, but excluding elements corresponding to the index

(3) numbers[-5:-3]

[6, 7] #注意索引的顺序

(4) numbers[3,3]

[] #空列表

(5) numbers[-5, 9]

[6, 7, 8, 9] #混合正负索引

(6) numbers[-20, 20]

[1, 2, 3, 4, 5, 6, 7, 8, 9, ten] #好像不存在index out of range issues

(7) Numbers[8,-8]

[] #索引区间为空

2.3 Sequence Addition

Note: Two sequences of the same type can be added

2.4 Multiplication

2.5 Membership: In

2.6 Length, min and Max values

Len ()--Returns the number of elements contained in the sequence

Min ()-the largest element in a sequence

Max ()-the smallest element in a sequence

3. List

4. Tuples
