Hey guys! Can you describe me what’s the difference between these two codes. Coz both of them give the same result

Question

def average(n1,n2):
m = (n1 + n2)/2
return m

a = int(input("A= "))
b = int(input("B= "))

avrg = average(a,b)
print(round(avrg,2)) #what’s a ROUND? I DON’t KNOW

def average(n1,n2):
m = (n1 + n2)/2
return m

a = int(input("A= "))
b = int(input("B= "))

average(a,b)

Answer 1

Hey Wangzi
Python's round() function requires two arguments. First is the number to be rounded. Second argument decides the number of decimal places to which it is rounded.Here, the second parameter is optional. To round the number to 2 decimals, give second argument as 2. If third digit after decimal point is greater than 5, last digit is increased by 1.
>>> round(1.4756,2)
1.48
>>> round(1.3333,2)
1.33

Answer 2

Python provides an inbuilt function round() which rounds off to the given number of digits and returns the floating point number, if no number of digits is provided for round off , it rounds off the number to the nearest integer.
SYNTAX:-
round(number, number of digits)

Where,
1) number - number to be rounded
2) number of digits (Optional) - number of digits up to which the given number is to be rounded.

EXAMPLE:-

# for integers

print(round(15))

# for floating point

print(round(51.6))
print(round(51.5)) 
print(round(51.4))

OUTPUT:-
15
52
52
51

Note:-
When .5 is there round will return the nearest even integer.
