This article shares with you the content of an example analysis of the basics of Python. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. The markers in python:

1. The name given to the variable is the marker.

Case-sensitive. MyName and myname are two different markers.

3. The first character can be underlined or begin with a letter, not a number. Chinese characters can be used as markers, but it is not recommended.

4. Keywords cannot be used as markers

5. Python built-in functions cannot be used as markers, such as print

2. Variable use in Python: 1. String variable

2. Floating point variable

3. Integer variable and bool variable

III. Sentences in Python

One line of code represents a statement. Generally speaking, a statement ends without a semicolon, either with or without a semicolon, and is not recommended. The Python programming specification is a statement.

No semicolon

1 、 a=b=c=10

2 、 a=b=c=20

You can assign values to abc.

IV. Comments in Python

Starts with #, followed by a space, followed by the contents of the comment

# comment content

It is OK without spaces, but it is recommended to add programming specifications.

You can make comments on a separate line, and you can follow them after the statement.

Use comments to tell Python to encode and put them on the first or second line

# coding=utf-8

You can also use #-- coding:utf-8--

5. Modules in Python:

A module is a file.

There are three forms of import modules:

1 、 inport

In this way, all code elements in the m2 module are imported, and the access needs to be prefixed with m2.

2 、 from import

This will import the x variable in m2 and do not need to be prefixed with m2 when accessing it.

3 、 from import as

This will import the x variable in m2 and give the variable an alias. There is no need to add the prefix m2 when accessing it.
