Python Program - Find the Square Root

here's a Python program that finds the square root of a number using the math module:

import math

# Define a number
num = 25

# Find the square root using the math.sqrt() function
sqrt_num = math.sqrt(num)

# Print the square root
print("The square root of", num, "is", sqrt_num)

In this program, we first import the math module, which provides mathematical functions and constants.

We then define a number called num that we want to find the square root of.

To find the square root of num, we can use the math.sqrt() function, which takes a number as its argument and returns its square root.

We assign the result of math.sqrt(num) to a variable called sqrt_num.

Finally, we can print the square root using the print() function and string formatting.

If we run this program, the output will be:

The square root of 25 is 5.0

Note that the math.sqrt() function only works with real numbers, and will raise a ValueError exception if called with a negative argument. If you need to find the square root of a negative number, you can use the cmath.sqrt() function from the cmath module, which works with complex numbers.
