This article focuses on "how to use the built-in general functions of the python container". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor learn how to use the built-in general functions of the python container.

What are the common operations that are easy to use with this data?

In addition to the addition, deletion, query and modification of data (in addition to the immutable length of tuple and immutable elements), we also need the following operations:

Compare and compare operation

Calculate the number of elements

Print out the container

Get container type

Use = = to manipulate whether the symbol alignment is equal

Len (Container object)

Str (Container object)

Type (Container object) # type supports judging the types of various objects

Let's take a look at the code of several containers.

Strictly speaking, we do not use the tuple tuple type as a data container.

We use it more to describe fixed-length structures.

#! / usr/bin/env python#-*-coding: utf-8-*-# @ Time: 12:40 on 2021-11-8 # @ Author: LeiXueWei# @ CSDN/Juejin/Wechat: Ray academic Committee # @ XueWeiTag: CodingDemo# @ File: _ _ init__.py.py# @ Project: hellotuple1 = ("name", "leixuewei") tuple2 = ("name", "leixuewei") print ("len:", len (tuple1) print ("= =:" Tuple1 = = tuple2) print ("dict1:", str (tuple1)) print ("type:", type (tuple1))

The running effect is as follows:

Here is the same operation for list:

#! / usr/bin/env python#-*-coding: utf-8-*-# @ Time: 12:40 on 2021-11-8 # @ Author: LeiXueWei# @ CSDN/Juejin/Wechat: Ray academic Committee # @ XueWeiTag: CodingDemo# @ File: commonlistops.py# @ Project: hellolist1 = ["name", "leixuewei"] list2 = ["name", "leixuewei"] print ("len:", len (list1) print ("=:", list1 = = list2) print ("list1:" Str (list1)) print ("type:", type (list1))

The following is the operation of the dict dictionary type:

#! / usr/bin/env python#-*-coding: utf-8-*-# @ Time: 12:40 on 2021-11-8 # @ Author: LeiXueWei# @ CSDN/Juejin/Wechat: Ray academic Committee # @ XueWeiTag: CodingDemo# @ File: _ _ init__.py.py# @ Project: hellodict1 = {"name": "leixuewei"} dict2 = {"name": "leixuewei"} print ("len:", len (dict1) print ("= =:" Dict1 = = dict2) print ("dict1:", str (dict1)) print ("type:", type (dict1)) so far I believe you have a deeper understanding of "how to use the built-in general functions of the python container".
