Python comments and operators are like, I believe that many inexperienced people do not know what to do, so this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

1. Multi-file project walkthrough

Create two python files under day02

Click on a file and right-click to run it. A file box will appear in the upper right corner.

Run the second file, and the steps are the same

Delete output box contents

two。 Comments (the interpreter will not interpret the content on the right side of #) 2.1 single-line comments (line comments)

# followed by a space, there will be no grammatical errors

# this is the first comment print ("hello world") # this is the second comment print ("cat")

In the comment on the right, there are two spaces between code and #

Print ("pig") # second single-line comment 2.2 Multiline comment (block comment) "" this is multiline comment "" 3. Arithmetic operator 3.1operator a = 21b = 10print (a + b) print (a-b) print (a * b) print (a / b) print (a% b) # remainder print (a * * b) # Power print (a / / b) # divisible

Extension: "string"

"-" * 10

3.2 priority

Multiply and divide first and then add and subtract

Sibling: from left to right

You can use () to adjust the calculation priority

Sort arithmetic operators from high to low precedence

Example:

C = 2d = 3e = 4print (dwindles c + d * e) print (dudes * (c + d) * e)

Output
