My Name is:sena

Take values from user like User Class¶

Calculations After taking values¶

In [4]:
operation = int(input('Choose an operation from 1 to 4: '))

variable_1 = int(input('Enter variable 1: '))
variable_2 = int(input('Enter variable 2: '))

if operation == 1:
    print(variable_1, "+", variable_2, "=", variable_1 + variable_2)
elif operation == 2:
    print(variable_1, "-", variable_2, "=", variable_1 - variable_2)
elif operation == 3:
    print(variable_1, "*", variable_2, "=", variable_1 * variable_2)
elif operation == 4:
    if variable_2 == 0:
        print("Error because division by zero is not allowed.")
    else:
        print(variable_1, "/", variable_2, "=", variable_1 / variable_2)
else:
    print("Invalid operation")

Choose an operation from 1 to 4: 4
Enter variable 1: 450
Enter variable 2: 45
450 / 45 = 10.0
