I should remember how to do this.
So you have 3.141592653 in a variable and you want to output up to the 2 decimal points. Here is how you can do it.
a = 3.141592653
print("{:.2f}".format(a))
The code above returns string. If you want to convert it to an actual float value, you can surround it with float.
Here is a Python3 way. This is cleaner.
print(f"{a:.2f}")
