# Python square root generator: Generate square, cube roots of numbers

## Python: Generators Yield Exercise-13 with Solution

Write a Python program to create a generator that generates the square, cube roots of numbers from 1 to n.

Sample Solution:

Python Code:

``````import math

def roots_generator(n):
for i in range(1, n+1):
yield math.sqrt(i), i**(1/3)

# Accept input from the user
n = int(input("Input a number: "))

# Create the roots generator
roots_gen = roots_generator(n)

# Generate and print the square roots and cube roots
print("Square roots and cube roots of numbers from 1 to", n)
for i, (square_root, cube_root) in enumerate(roots_gen, start=1):
print("Number:", i)
print("Square root:", square_root)
print("Cube root:", cube_root)
print()
``````

Sample Output:

```

Explanation:

In the above exercise,

• The "roots_generator()" function is a generator function that yields the square root and cube root of numbers from 1 to n. It uses the math.sqrt() function from the math module to calculate the square root and the exponentiation operator ** to calculate the cube root.
• The program accepts a number from the user as n. It then creates the roots_generator generator from the input number. Finally, the enumerate function is used to iterate over the roots_gen generator and obtain both the index i and the square root and cube root values. By using enumerate with the start=1 parameter, the index i starts from 1. This allows us to print the correct number associated with each pair of roots.
