Hey guys, in this blog we will see a Python Program to Compute the Power of a Number.
Example 1: Calculate the power of a number using a while loop
# Python Program to Compute the Power of a Number
base = 5
exponent = 4
result = 1
while exponent != 0:
result *= base
exponent-=1
print("Answer = " + str(result))
Output
Answer = 625
- Here we are using a while loop to calculate the power of a number.
- It just keeps on multiplying the base number exponential times.
- It is the most brute-force approach.
Example 2: Calculate the power of a number using a for loop
base = 5
exponent = 4
result = 1
for exponent in range(exponent, 0, -1):
result *= base
print("Answer = " + str(result))
Output
Answer = 625
- Here we are using a for loop to calculate the power of a number.
- It is almost similar to the above approach.
- It just keeps on multiplying the base number exponential times.
- It is also a brute-force approach.
- Our for loop will go like 4,3,2,1.
Example 3: Calculate the power of a number using the pow() function
base = 5
exponent = -4
result = pow(base, exponent)
print("Answer = " + str(result))
Output
Answer = 0.0016
- The easiest way to find the power of a number is by using the pow() function.
- It takes two arguments base and exponent.
