How to rework the basic operation of list by Python

In this issue, the editor will bring you about the basic operation of how to rewrite the list of Python. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

At the beginning of this section, let's move on to new knowledge points.

1. List definition

Definition: similar to an array, but not entirely an array.

In python, it is also called sequence.

Let's take a look at defining a list in code: name= [Lao Liu, Lao Jin, Lao Yu]

This list, which we say as an array in other languages, we want the index of the list.

Note: the index of the first position in the sequence is 0

The index of the second location is 1

The index of the third location is 2.

two。 List value

1. Use the index to take a positive value from 0

2. Use the negative number-1 to start the reverse value

For example, in the list name in the above example, the first value we get is name [0]

3. Case exercise

Randomly concatenate the two lists into one sentence.

In this case, we are going to use random numbers.

Note: the randint function is a doubly closed interval, which can obtain the values at both ends.

Comparison: range function is half open and half closed

4. Summary and emphasis

1. Master the value method of the list

2. Master the interval that distinguishes range and randint functions.

5. Case source code

From random import randintname= ["Lao Liu", "Lao Jin", "Lao Yu"] work= ["programmer", "professor", "civil servant"]

For i in range (2): print (name [Randint (0jue 2)] + "Yes" + work [randint (0jue 2)]) the above is the basic operation of the Python rework list shared by the editor.
