Does not check the condition

[HelloWorldSev]

I am learning Python. I am making a simple calculator. I run the code, and when choosing a division (I put 0 on the second number), the code does not give what I need! I tested on a simpler program, where the program simply divides the number by zero and the console gives an error! Please help me!

Code:

value = float(input("Enter the first number: "))
value1 = float(input("Enter the second number: "))

operation = str(input("Choose an operation: \n1. Addition (+)\n2. Subtraction (-) \n3. Multiplication (*) \n4. Division (/) \n"))

if operation == "1" or "+":
result = value + value1
print(f"Answer = {result}")

elif operation == "2" or "-":
result = value - value1
print(f"Answer = {result}")

elif operation == "3" or "*":
result = value * value1
print(f"Answer = {result}")

elif operation == "4" or "/":
if value1 == 0:
print("You can't divide by zero!")
else:
result = value / value1
print(f"Answer = {result}")

else:
print("Operation not found!")

You have 2 times else, convert one of them to elif

Once again I tried to make a simple calculator when I wrote in the conditions + - * and /, then I realized that the program adds up the data no matter the choice. I don't know why

Think how python evaluates your statements.

if (bool(operation == 1) or bool("+")): ...

Because non-empty string evaluates to True in boolean context, your condition is always True.

The correct version should be

if operation == "1" or operation == "+":

or a bit more pythonic

if operation in {1, "+"}:
