Python 3 - Number sqrt() Method
Description
The sqrt() method returns the square root of x for x > 0.
Syntax
Following is the syntax for sqrt() method −
import math math.sqrt( x )
Note − This function is not accessible directly, so we need to import the math module and then we need to call this function using the math static object.
Parameters
x − This is a numeric expression.
Return Value
This method returns square root of x for x > 0.
Example
The following example shows the usage of sqrt() method.
#!/usr/bin/python3 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))
Output
When we run above program, it produces the following result:
math.sqrt(100) : 10.0 math.sqrt(7) : 2.6457513110645907 math.sqrt(math.pi) : 1.7724538509055159
