round() in Python

  • A+
Category:Languages

I'm currently learning python with pycharm as IDE. While using the round() function I noticed that I get two different results depending on wether I don't explicitly choose the number of decimal places to include or choosing the number to be 0.

x = 4.1 print(round(x)) print(round(x, 0)) 

It prints the following:

4 4.0 

What is the difference?

 


When you specify the number of decimals, even if that number is 0, you are calling the version of the method that returns a float. So it is normal that you get that result.
