Hello Harry, thanks for the exercise! It was fun working on it. Here's the code:
n1=int(input("Enter your first number"))
n2=int(input("Enter your second number"))
opp=input("Choose operator (+ - * /)")
if opp=='+':
if n1==56 and n2==9:
print('77')
else:
print(n1+n2)
elif opp=='-':
print(n1-n2)
elif opp=='*':
if n1==45 and n2==3:
print('555')
else:
print(n1*n2)
elif opp=='/':
if n1==56 and n2==6:
print('4')
else:
print(n1/n2)

Nice exercise, it triggers the methods to add some exclusions behaviors in thousands or millions normal cases.
Truly you are a wonderful tricky programmer.

Pretty late to answer this but here we go!

# Design a calculator which can input 2 numbers and perform an operation according to the user.
# There must be a fault in the calculator. The fault must be, if the operation performed is 45*3(555), 56+9(77), 56/6=4
# the answer must be given accordingly, as per the brackets corresponding.
print("Welcome to the best calculator you will ever find for your math test!")
a=float(input("Enter your first number:"))
b=float(input("Enter your second number:"))
op=input("Enter the operation you want to perform (+, -, *, /):")
if (a, b)==(45, 3) and op=="*":
print("The answer is:555")
elif (a, b)==(56, 9) and op=="+":
print("The answer is:77")
elif (a, b)==(56, 6) and op=="/":
print("The answer is:4")
else:
if op=="+":
print("The answer is:", a+b)
elif op=="-":
print("The answer is:", a-b)
elif op=="*":
print("The answer is:", a*b)
elif op == "/":
print("The answer is:", a/b)
else:
print("Enter a valid operation.")

Bhai Kya Excercise de diya..! bahar Hun Phir Bhi Maine Excercise book nikal ke code likhne laga!....Hope Calculator Faulty (Kam Karne Wala Ho jaye)

Thankyou for making it easy for us

Hi harry, thanks for uploading these videos. I have a suggestion for you. I struggle all the time applying my programming knowledge after learning it practically. Can you give some small project to us after certain lectures so that we can develop our programming skill?

M a bit late, but love your channel, I'm in my first year now so started just now
love your exercises,

i created it broo....

[vincyjoseph]

Thank you so much fo your efforts in this tutorial... 🙏

[amandeepkaur-jltr]

i have just started learning python . this is my first ever language to learn. here is my code:-


d1={"45*3":"555", "56+9":"67", "56/6":"4"}

print("Type your problem")
v1=input()

if v1 in d1:
print(d1.get(v1))
else:
print(eval(v1))

thanku Harry love love love.

Keep going man, I have my resolution of 2019 to be awesome in Python and I know you can help me a lot.
