Is declaration is compulsory mam, you declared that bill=0, other wise can I directly assign the value like bill=100

[gurutej]

mam one doubt if valid indicate that he entered wrong size where sholud we add that statement invalid input so i need to get in valid input and get terminated the program

[anisha_sivakumar_]

bill=0
pizza=input("Enter size of pizza(S/M/L):")
if(pizza=="S" or pizza=="s"):
ses=input("Do you want seasoning(Y/N): ")
if(ses=='Y' or ses=='y'):
bill+=100+30
else:
bill+=100
elif(pizza=="M" or "m"):
ses=input("Do you want seasoning(Y/N): ")
if(ses=='Y' or ses=='y'):
bill+=200+50
else:
bill+=200
elif(pizza=="l" or "L"):
ses=input("Do you want seasoning(Y/N):")
if(ses=='Y' or ses=='y'):
bill+=300+20

bill+=300
extra_cheese=input("extra cheese ?(Y/N)")

[viswanath]

mam your explanation is very well, but one small feedback there is a one error in your code if(size =='S' or size=='s'):, before this we need to give input size=(input("enter size of pizza:")), Then only we will get correct output.

[RaniGanaparthi]

mam can we use
if add - pepproni == 'y' and size == 's'
as a one line . instead of using two if conditions ??
