#Python supports multiple returns 
#you only write ONE return statement, and you list return variables 
#separated by coma

#Write a function total_ave that has one parameter, num, number of items 
#to read. The function reads num integers and finds and returns sum and 
#average of input numbers 

#write main to test your function
def total_ave(num_items):
	sum=0
	for i in range(num_items):
		n=int(input("enter number "))
		sum=sum+n
	ave=sum/num_items
	return sum, ave
	#DON'T WRITE
	#return sum
	#return ave
	#this is not correct implementation
def main():
	num_items=int(input("enter number of items "))
	res1, res2 = total_ave(num_items)
	#res1 will get value of sum
	#res2 will get value of ave
	print("sum of all items is", res1)
	print("average is", res2)
