tutorial on using the sqrt () method for square root calculation in Python

The sqrt () method returns the square root of x (x>0).
Grammar

The following is the syntax for the sqrt () method:

Import mathmath.sqrt (x)

Note: This function is not directly accessible, so we need to import the math module and then call this function with the static object of math.
Parameters

• X--This is a numeric expression.

return value

This method returns the square root of x for x>0.
Example

The following example shows the use of the sqrt () method.

#!/usr/bin/pythonimport Math  # This would import math Moduleprint "math.sqrt": ", Math.sqrt () print" Math.sqrt ( 7): ", Math.sqrt (7) print" Math.sqrt (Math.PI): ", Math.sqrt (Math.PI)

When we run the above program, it produces the following results:

MATH.SQRT (+): 10.0math.sqrt (7): 2.64575131106math.sqrt (Math.PI): 1.77245385091
