How to limit decimal numbers in Python?
In this article, we’ll learn how to limit decimal numbers in Python, in a simple way with Python’s own resources.

Hey you programmer, okay? Let’s learn more about Python!
We can solve this problem by rounding the number with the round function, for example
Let’s see it in practice:
n = round(3.32424, 2) print(n) // 3.32
The first argument is the number to be rounded and the second is how many decimal places we want to display
We can also format the number, also choosing how many places to display, let’s see it:
n2 = 4.38991 print("%.2f" % n2) // 4.39
So we use a special Python syntax to format the number the way we need it.
You can also use the format feature, which came in Python version 3
Making it even easier to format the number with decimal places, see it running:
t = 7.98562434234 print('The value is {:.4f}'.format(t))
Very similar to our second example, but this one is already included in the print
And its syntax is also easy to understand, we can decide the number of places
Conclusion
In this article we learned how to limit decimal numbers in Python
We use the round function that accepts as parameters the number in float and also how many places we want it to be rounded
We also learned another way of formatting the number, using a special Python syntax.
