#Write a program that reads 7 real numbers. Each number indicates the Celsius 
#temperature for one day. The program finds and prints the average Fahrenheit 
#temperature for these 7 days. Use the following formula to convert Celsius to 
#Fahrenheit: Fahrenheit = (9/5)* Celsius + 32 

sum=0
for i in range(1,8): #i=1, 2, 3, 4, 5, 6, 7
	print("enter Celsius for day", i)
	C=float(input("enter Celsius "))
	F=(9/5)*C + 32
	sum=sum+F
print("average Fahrenheit", sum/7)
