We are given a number and asked to find the square root of the number in python.

There are two ways through which we can find the square root of a number:

  • Using ** operator with 0.5 as exponential value.
  • Using math library.

Square Root of a Number in Python using ** Operator

  1. Take a number as input.
  2. Check if the number is positive. If yes then Step 3 else Step 4.
  3. Find square root using ** i.e sqrt = num ** 0.5. Output the result.
  4. End Program.

Output

Square root of a number in python

Square Root of a Number in Python using ‘math’ Library

We have to repeat almost the same steps as done in the above program. But instead of ** operator, we will use math.sqrt() method.

Note: Make sure to import math library to use math.sqrt() inbuilt method.

Output
