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:

x : base number
y : exponent
z : module (optional)

Possible circumstances with the parameter of pow ()

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.

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:

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