Example 1: write a program to input a number and display its double and half values using shift operator in python

# Write a program to input a number and display its Double and Half values using SHIFT operator.

print("Hi \nThis is a basic calculator \nwhich doubles or divides into half the value entered in it")
i = int(input("pls enter your number:\n"))
print("what do you want to do? \nwarning: \nenter only the alphabet of the option and no symbols.")
print("you can enter both the options alphabet to get both the values")
print("This program gives and takes only integer value of double, half and input")
opt = input("options:- \na.double\nb.half\n")
if opt == "a":
    j = i << 1
    print("double", j)
elif opt == "b":
    k = i >> 1
    print("half:", k)
elif opt == "ab" or opt == "a b" or opt == "ba" or opt == "b a" or opt == " ab" or opt == "ab " or opt == " ab " or opt == " a b" or opt == "a b " or opt == " a b ":
    j = i << 1
    k = i >> 1
    print("number:", i)
    print("double:", j)
    print("half:", k)
else:
    print("inputs are wrong")
    exit()
