Example
The following example shows the usage of sqrt() method.
Live Demo
#!/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
