3. Python function interpretation

4. Code interpretation description

Print refers to a function (syntax) of displaying, outputting and printing in Python language.

The main function of double quotation marks is to enclose the text to be displayed in double quotation marks.

Hello world is a sentence that I want to show. You can display any sentence that says: beijing Beijing is OK, too.

Change the content in the double quotation marks to something else, why don't you try it?

5. If you want to write in Chinese # coding=utf-8print ('Hello, World!')

Note:

The code part of Python should be written in English input method, not Chinese input method.

When we write the file abc.py, when we name the file, we only use these characters in English (a-zA-Z0-9 characters -) to name the file.

Do not use Chinese for naming files, do not use special symbols, and do not add spaces in the middle.

File names are strictly size sensitive.
