Python pow() Function
Python pow() function returns the result of the first parameter raised to the power of the second parameter.
Python pow() Function Example
Python3
print(pow(3,2)) |
Output:
9
Python pow() Function Syntax
Syntax: pow(x, y, mod)
Parameters :
- x : Number whose power has to be calculated.
- y : Value raised to compute power.
- mod [optional]: if provided, performs modulus of mod on the result of x**y (i.e.: x**y % mod)
Return Value : Returns the value x**y in float or int (depending upon input operands or 2nd argument).
Example 1: Python pow() with three arguments
Python3
# Python code to demonstrate pow()print("The value of (3**4) % 10 is : ", end="") # Returns 81%10# Returns 1print(pow(3, 4, 10)) |
Output:
The value of (3**4) % 10 is : 1
Implementation Cases in pow() :
Python3
# Python code to discuss negative# and non-negative cases # positive x, positive y (x**y)print("Positive x and positive y : ", end="")print(pow(4, 3)) print("Negative x and positive y : ", end="")# negative x, positive y (-x**y)print(pow(-4, 3)) print("Positive x and negative y : ", end="")# positive x, negative y (x**-y)print(pow(4, -3)) print("Negative x and negative y : ", end="")# negative x, negative y (-x**-y)print(pow(-4, -3)) |
Output:
Positive x and positive y : 64 Negative x and positive y : -64 Positive x and negative y : 0.015625 Negative x and negative y : -0.015625
