Python is one of the high-level object-oriented programming languages. This language is used to create a variety of applications and websites.
Python is the perfect choice for top professionals to beginners, thanks to its simple yet elegant structure. This language is also appreciated for its rigor, power, and speed, which are present in all operating systems.
“How to get square root in Python” is one of the most common programming questions. So, what can we do? We would collaborate to find the best solutions.
The best ways to get square root in Python
A number’s square root is a value that returns the same number when multiplied by itself. Because 6 x 6 = 36, the square root of 36 is 6. However, (-6) × (-6)= 36, so (-6) is also the square root of 36. In Python or any other programming language, there are several methods for calculating the square root of a number. And in this tutorial, we’ll go over four different methods for calculating the square root of a number.
Are you working on a quadratic equation? Perhaps you need to determine the length of one side of a right triangle. The Python square root function, sqrt(), can help you quickly and accurately calculate solutions to these and other equations.
Solution 1: Use the sqrt()
The sqrt() function is a predetermined method which is used to calculate the square root, so you can use it to get quare root in Python. Let’s learn more about this through the following example:
import math
print ("math.sqrt(49) : ", math.sqrt(49))
print ("math.sqrt(81) : ", math.sqrt(81))
Output:
math.sqrt(49) : 7.0
math.sqrt(81) : 9.0
Solution 2: Use the math.pow()
You alo can get square root in Python by using math.pow()
. Look at this example:
import math
SquareRoot = math.pow(81, 0.5)
print(" The Square Root of the given number {0} = {1}" .format(81, SquareRoot))
Output:
The Square Root of the given number 81 = 9.0
Solution 3: Use the exponent operator
The square root operation is carried out by the exponent operator, indicated with the symbol **
, just like the pow()
function.
Let’s define your own function to find the square root of an integer, it makes the situation more interesting. Let’s consider our below program:
# Utilizing the exponent operator to get the square root in Python
def sqRoot(n):
if n < 0:
return
else:
return n**0.5
print(sqRoot(36))
Output
6.0
We have started by creating a function called sqRoot (n)
. The equation n**0.5
, which computes the square root and stores the result in the variable x
, has been added after that. We enter the number which we wish to specify the square root in the position of parameter n
or the argument when we call the function we have just specified.
