### How to Calculate Square Root in Python - Python Poo

1. To calculate the Square Root in Python we have basically 5 methods or ways. The most common or easiest way is by using a math module sqrt function. Python sqrt function is inbuilt in a math module, you have to import the math package (module)
2. Python has a predefined sqrt() function that returns the square root of a number. It defines the square root of a value that multiplies itself to give a number. The sqrt() function is not used directly to find the square root of a given number, so we need to use a math module to call the sqrt() function in Python. For example, the square root of 144 is 12. Using math.sqrt() metho
3. Python has three ways to get the positive square root of a number: The math.sqrt() function returns the square root as a precise floating-point value. (This function is what you need 95% of the time.
4. # Python Program to calculate the square root # Note: change this value for a different result num = 8 # To take the input from the user #num = float(input('Enter a number: ')) num_sqrt = num ** 0.5 print('The square root of %0.3f is %0.3f'%(num ,num_sqrt)) Output. The square root of 8.000 is 2.82
5. A square root of a number is a number which when multiplied by itself, returns the same number. For example : For the number 49, 7 x 7 = 49. Hence, we can say 7 is the square root of 49. Calculating the Square Root in Python

Case 1 : If mid is the middle number in the range 1 N and N == ( mid * mid ), the middle number is evidently the square root of the number N.. Case 2 : If ( mid * mid ) is greater than N, it means that mid is greater than the floor of the square root of N so we binary search in. Using this code, if I am trying to solve for the square root of 123456 with an initial guess of 600, the Python program quickly converges on an answer using the Babylonian Method.
