Question

With the use of if statements, create a Calculator program that only uses 1 input.

For example, if a person inputs 2 + 3, the program should print 5.

If the person inputs 3 - 1, the program should return 2.

If the person input 4 / 2, the program should return 2.

If the person inputs 3 * 2, the program should return 6.

Python

Answer 1

expression = input("Enter a simple expression: ")
n1 = float(expression.split()[0].strip())
n2 = float(expression.split()[2].strip())
ch = expression.split()[1].strip()

print(expression + " = ", end='')
if ch == '+':
    print(n1 + n2)
elif ch == '-':
    print(n1 - n2)
elif ch == '*':
    print(n1 * n2)
elif ch == '/':
    print(n1 / n2)
elif ch == '%':
    print(n1 % n2)
elif ch == '**':
    print(n1 ** n2)
else:
    print('Unknown')
