What does the / / symbol refer to in Python

Today, the editor will share with you the relevant knowledge of what the / / symbol in Python refers to. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

/ / what does the symbol mean

The / / in Python means to round down

A _.

For example:

5Universe 2 (2.5 rounded to negative infinity to 2), and-5 racer to negative infinity 3 (- 2.5 rounded to negative infinity to-3)

The difference between / and / /

What is the difference between / and / in the Python language?

In Python / represents floating-point division and returns a floating-point result, that is, the result is a floating-point number, while / / represents integer division in Python and returns the largest integer greater than the result, which means that the division result is rounded down.

For example, print ("6 / 4 =" + str (6 / 4)) print ("6 / 4 =" + str (6 / 4))

Results:

6 / 4 = 1

6 / 4 = 1.5

Python arithmetic operator

The following hypothetical variables await 10 and bounce 21:

The operator +: add-two objects are added together, and the instance aplyb outputs the result 31.

The operator--: minus-- gets a negative number or one number minus another, and the example Amurb outputs the result-11.

Operator: multiply-multiply two numbers or return a string that has been repeated several times. The example ab outputs the result.

The operator /: divides-x by y, and the example bplink an outputs 2.1.

Operator%: modulo-returns the remainder of division, b% an outputs result 1.

Operator: power-returns x to the power of y, and ab to the power of 21 of 10.

Operator / /: take integral division-take the integer close to the quotient, example > 9 prime 24 >-9 prime 25
