Important code for class 11 do yourself and ask your doubt

In this article I am sharing some important question for class 11 practical and basic code which is the basic part of the python. This part build the concept for any programming language. There is some interesting logics which make this language play with codes. When you play with code you can solve any problem in short time.  

Q – 1. Rewrite the following code fragment using if…elif..else statement:

color = input(“Enter the color :”)

if (color==”red”):

   print(“Arun House”)

if(color==”blue”):

   print(“Aditya House”)

if(color==”yellow”):

  print(“Ravi House”)

if(color==”green”):

 print(“Bhaskar House”)

if(color!=”red” or color!=”blue” or color!=”yellow” or color!=”green”)

 print(“Not a valid color name!!!!”)

Q – 2 What will the output of the following code fragment when the input is 6, 5, and 12?

if month>=6 and month<=9:

   print(“Term – I”)

elif month>=10 and month<=4:

   print(“Term – II”)

else:

   print(“Vacation”)

Q-3 Write a program to compute the net amount to be paid by a customer in the following format:
