Help me to correct my code of simple calculator. My two outputs are correct while third output is throwning error.

Question

Write a program that performs the tasks of a simple calculator. The program should first take an integer as input and then based on that integer perform the task as given below.
1. If the input is 1, then 2 integers are taken from the user and their sum is printed.
2. If the input is 2, then 2 integers are taken from the user and their difference(1st number - 2nd number) is printed.
3. If the input is 3, then 2 integers are taken from the user and their product is printed.
4. If the input is 4, then 2 integers are taken from the user and the quotient obtained (on dividing 1st number by 2nd number) is printed.
5. If the input is 5, then 2 integers are taken from the user and their remainder(1st number mod 2nd number) is printed.
6. If the input is 6, then the program exits.
7. For any other input, then print "Invalid Operation".
Note: Each answer in next line.

Answer 1

Before: elif n (>) 1 or n>6

After: elif n (<) 1 or n>6

Answer 2

Input -> https://ibb.co/XFCxWFq

Output -> https://ibb.co/0K760Nn

This is another code runs quite well.
But not on sololearn.

@simba
See it isn't working

Answer 6

It's working fine on other ide(pyroid).
But sololearn doesn't efficient to infinite loops.
That's why it's showing eof error.
Somehow, you can try this

I have just edited my code.

Answer 7

@Simba
Please answer this question that
on taking an input of 7 compiler is giving no output instead of printing " invalid operation"

It's similar to that of previous code.Can you tell me what changes you have made in this code.

try:
while True:
n = int(input())
num1 = int(input())
num2 = int(input())

if n==1:
print(num1 + num2)

elif n == 2:
print(num1 - num2)

elif n == 3:
print(num1 * num2)

elif n == 4:
print(num1 / num2)

elif n == 5:
print(num1 % num2)

elif 1 > n or n > 6:
print("Invalid Operation")
except:
exit()

Answer 8

See after this output is showing no output. When we give input of 7

Answer 9

Try this, all test cases will run. But it's throwing error on sololearn.
My problem has been shorted thank you for your efforts

Happy coding!

Answer 10

Glad to hear that.
Yeah, interactive programs don't play well with codeplayground, as it needs all inputs required by the program upfront.
For small no of inputs the following workaround works quite well :)

Answer 11

while True:
choice = int(input())
if (choice>=1 and choice<=5):
num1 = int(input())
num2 = int(input())
if choice == 1:
res = num1 + num2
print(res)
elif choice == 2:
res = num1 - num2
print(res)
elif choice == 3:
res = num1 * num2
print(res)
elif choice == 4:
res = num1 // num2
print(res)
elif choice == 5:
res = num1 % num2
print(res)
elif choice == 6:
exit()
else:
print("Invalid Operation")

Answer 12

while True:
a = int(input())
if a>0 and a<6:
x=int(input())
y=int(input())
if a==1:
o=x+y
elif a==2:
o=x-y
elif a==3:
o=x*y
elif a==4:
o=x/y
else:
o=x%y
print(int(o))
elif a==6:
quit()
else:
print("Invalid Operation")

Answer 13

n = int(input())
num1 = int(input())
num2 = int(input())
if n>=1 and n<=5:
print(num1 and num2)

if n==1:
print(num1 + num2)

elif n == 2:
print(num1 - num2)

elif n == 3:
print(num1 * num2)

elif n == 4:
print(num1 / num2)

elif n == 5:
print(num1 % num2)

elif n == 6:
exit()

else:
print("Invalid Operation")

Answer 14

May be you are solving and putting all the operators correctly but forgot to handle the division by 0 error.

Answer 16

z = int(input("input operation from 1 to 6: "))

if (z>=1 and z<=5) :
x = int(input("Enter first number: "))
y = int(input("Enter second number: "))
if(z==1):
sum = x+y
print("the sum of two number is: ",sum)
elif(z==2):
difference = x-y
print("the difference of two number is: ",difference)
elif(z==3):
product = x*y
print("the product of two number is: ",product)
elif(z==4):
divide = x/y
print("the divide of two number is: ",divide)
elif(z==5):
remainder = y%x
print("the remainder of two number is: ",remainder)
elif(z==6):
exit()
else:
print("Invalid Operation")

Please, suggest me what I am doing wrong?

Answer 17

n = int(input())
num1 = int(input())
num2 = int(input())
if n==1:
print(num1 + num2)
elif n == 2:
print(num1 - num2)

elif n == 3:
print(num1 * num2)

elif n == 4:
print(num1 // num2)

elif n == 5:
print(num1 % num2)

elif 1 > n or n > 6:
exit()
else:
print("Invalid Operation")
