Certification: Basic Level Accuracy: 80.31% Submissions: 259 Points: 5

Write a Python program that calculates the square root of a given number.

Example 1
    
  
  • Input: 16
    • 
  
  • Output: 4.0
    • 
  
  • Explanation: 
    
      
      
    • Step 1: Calculate the square root of 16.
      • 
      
    • Step 2: √16 = 4.0.
      • 
      
    • Step 3: Return 4.0 as the result.

Solution Hints

     
  • Use math.sqrt() function: import math; result = math.sqrt(num)
    •   
  • Use the exponentiation operator: result = num ** 0.5
    •   
  • Implement Newton's method for manual calculation
    •  
  • Use binary search method for manual implementation

The following are the steps to find the Square Root of a Number:

 1. Define a function `square_root(n)` that takes a number.

 2. Compute the square root using `n ** 0.5`.

 3. Return the computed value.

 4. Call `square_root(25)` and store the result.

 5. Print the square root.
