Xiaobian to share with you what are the operators in Python, I believe most people still do not know how, so share this article for your reference, I hope you have a lot of gains after reading this article, let's go to understand it together!

arithmetic operator

Because it is an integer, it can also perform basic operations in mathematics.

Arithmetic operators are a type of operator

is a symbol used to perform basic arithmetic operations, used to process four arithmetic operations

precedence of arithmetic operators

The precedence of operators is the same as in mathematics, and when doing mathematical calculations in Python, the same is true:

Multiply and divide then add and subtract

Sibling operators are computed from left to right

You can adjust the priority of calculations using ()

The following tables are arranged in descending order of arithmetic priority

identity operator

Is compares whether two instance objects are identical, whether they are the same object, and whether they occupy the same memory address. Leibniz said: "There are no two identical leaves in the world." This is exactly such a comparison, comparing whether they are the same leaf (i.e. whether the id of comparison is the same, which is similar to the identification card of a person).

Identity operators are used to compare storage locations of two objects

The id() function is used to get the memory address of the object.

Identity Operator Case:

#negating False directly returns True print(not False)# 5>3 returns True, 20.0 is greater than 10, so the result returns True print(5 > 3 and 20.0 > 10) # 4>=5 returns False,"c">"a" returns True. or returns True print(4 >= 5 or "c" > "a")

memory-resident

That's all for "What are the operators in Python?" Thanks for reading! I believe that everyone has a certain understanding, hope to share the content to help everyone, if you still want to learn more knowledge, welcome to pay attention to the industry information channel!
