Python program to calculate the square root of a given number:
import math
def calculate_square_root(number):
return math.sqrt(number)
# Example usage
number = float(input("Enter a number: "))
result = calculate_square_root(number)
print("The square root of", number, "is", result)
```
This program imports the `math` module, which provides a `sqrt()` function to calculate square roots. Then, it defines a function `calculate_square_root()` that takes a number as input and returns its square root. Finally, it prompts the user to enter a number, calculates its square root, and prints the result.
