Rounding In Python

Question

Code:

import math
x = 5.6
y = round(x)
print(y)
z = round(x,-1)
print(z)

Output:
6
10

Could someone please explain what effect the -1 has? Because when I change x to 4.3 for example my outputs are 4 and 0.

Answer 1

round(x,n)
Where n rounds of to the value specified
For eg round(80.23456, 2) : 80.23
it rounds off the first 2 digits after decimal
