Python is used extensively in the field of mathematics and statistics because of how easy it is to work with numbers.
One of the most common operations to do in any programming language is squaring a number.
In this post, we'll learn the three best ways to square a number in Python.
Multiplying a number by itself
The most straightforward way to square a number is to multiply it by itself.
That is because that is basically the definition of squaring a number.
Let's start off with the number we want to square:
PYTHONnumber = 5
Now, we can square it by multiplying it by itself:
PYTHONnumber = 5
number_squared = number * number
print(number_squared)
PYTHON25
Using the exponent operator
Python has an exponent operator that can be used to square a number.
While the operator can support any exponent, we can use it to square a number by using the exponent of 2.
Let's start off with the number we want to square:
PYTHONnumber = 5
Now, we can square it by using the exponent operator. To use the exponent operator, we simply put two asterisks (**) after the number we want to square:
PYTHONnumber = 5
number_squared = number ** 2
print(number_squared)
PYTHON25
Using the pow() function
The final way to square a number is to use the pow()
function.
This is a function that is built into Python and can be used to raise a number to any power.
To square a number, we simply pass in the number we want to square and the exponent of 2:
PYTHONfrom math import pow
number = 5
number_squared = pow(number, 2)
print(number_squared)
PYTHON25.0
Keep in mind that the output of the pow()
function is a float. If you want an integer, you can use the int()
function to convert it:
PYTHONfrom math import pow
number = 5
number_squared = int(pow(number, 2))
print(number_squared)
PYTHON25
Conclusion
In this post, we learned how to square a number in Python.
We learned how to do it by multiplying a number by itself, using the exponent operator, and using the pow()
function.
