The pow () function in Python

The pow () function built into Python returns the value of x with the power of y (x y ). If there is a third parameter, the function returns x to the power y, the module z.

In this article, TipsMake.com will learn about pow (), syntax, parameters and examples with you. Invites you to read the track.

The syntax of the pow () function in Python

 pow(x, y[, z])

The pow (x, y) function is equivalent to:

 x**y

Parameters of the pow () function

The pow () function has 3 parameters:

  1. x : base number
  2. y : exponent
  3. z : module (optional)

Possible circumstances with the parameter of pow ()

x
y
z
Integers (positive, negative) Positive integers May or may not Have integers (positive, negative) Negative integers Should not be included

Return value from pow ()

The return value of pow () depends on the type of parameter passed.

x
y
z
Return value
Positive integers Positive integers N / A Integers Positive integers Negative integers N / A Real numbers Negative integers N / A Positive integers Negative integers N / A integers Whole numbers (positive, negative ) Positive integers Whole numbers (positive, negative) Integers

Example 1: How does pow () work?

 # x, y là số dương (x**y) print(pow(2, 2)) # x là số âm, y là số dương print(pow(-2, 2)) # x là số dương, y là số âm (x**-y) print(pow(2, -2)) # x, y là số âm print(pow(-2, -2))

When you run the program, the output will be:

 4 4 0.25 0.25

Example 3: pow () has 3 parameters

 x = 7 y = 2 z = 5 print(pow(x, y, z))

Return value:

 4

In the above code, 7 2 is 49, 49% 5 is equal to 4.
