The topic of this article is numbers in Python. Describes each numeric type in detail, the various operators they apply, and the built-in functions used to process numbers. At the end of the article,
Sequence common operations of notes in the basic python tutorial, and python Sequence
Index
All the elements in the sequence are numbered-starting from 0. When a negative index is used, Python starts counting from the right, that is, from the
The sequence method is used in python, and the sequence method is used in python.
This article describes how to use sequence in python. Share it with you for your reference. The details are as follows:
Lists, tuples, and strings are all sequences,
In a powerful object-oriented general-purpose computer language such as the Python programming language, there are many usage methods that differ greatly from those common programming languages, for example, the Python sequence introduced today is

1.1 sequence Concept
The most basic data structure in pythn is sequence ).
Each element in the sequence is assigned a sequence number-element index. The first index is 0, the second
1. SequenceThe sequence type has the same access pattern: each of its elements can be obtained by specifying an offset. Multiple elements can be obtained one at a time by slicing operations. The subscript offset is from 0 to the total number of
1. Defining a SequenceThis article describes how to define a sequence in the Python language. The syntax for defining a sequence is similar to an array in Java, using a pair of brackets to enclose the values of elements in the sequence.The following
