Python Number sqrt() Method


Python number method sqrt() returns the square root of x for x > 0.


Following is the syntax for sqrt() method −

import math

math.sqrt( x )

Note − This function is not accessible directly, so we need to import math module and then we need to call this function using math static object.


  • x − This is a numeric expression.

Return Value

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


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

import math   # This will import math module

print "math.sqrt(100) : ", math.sqrt(100)
print "math.sqrt(7) : ", math.sqrt(7)
print "math.sqrt(math.pi) : ", math.sqrt(math.pi)

When we run above program, it produces following result −

math.sqrt(100) :  10.0
math.sqrt(7) :  2.64575131106
math.sqrt(math.pi) :  1.77245385091
