To calculate the square root of a number in python , we can use sqrt() method which returns the square root of number ( given that the number is > 0 )
To use the sqrt() function in python, we need to import the math module which provides access to the mathematical functions defined by the C standard.
So syntax to calculate python square root looks simply like this :
import math math.sqrt( x )
where x is > 0
So for example :
import math # This will import math module print “Square Root of 49 is ", math.sqrt(49)
Square Root of 49 is 7.0
method sqrt() returns a float value.
