PYTHON PRACTICE INTERACTIVE MODE (COMMAND LINE)

-
 You can use the basic mathematical operators:  1 >>> 3 + 3   6   >>> 3 - 3   0   >>> 3 / 3   1.0   >>> 3 / 2 1.5 >>> 3 * 3   9 >>> 3 ** 3   27  >>> num = 3 >>> num = num - 1  >>> print(num) 2 >>> num = num + 10 >>> print(num) 12 >>> num += 10 print(num) 22  >>> num -= 12 >>> print(num) 10 >>> num *= 10 >>> num  100 There’s also a special operator called modulus, % , that returns the remainder after integer division.  >>> 10 % 3   1  One common use of modulus is determining if a number is divisible by another number. For example, we know that a number is even if it’s divided by 2 and the remainder is 0.   >>> 10 % 2  0 >>> 12 % 2 0 Finally, make sure to use parentheses to enforce ...
