Integers

Python integers have an unlimited range, subject only to the available virtual memory. This means that it doesn't really matter how big a number you want to store is: as long as it can fit in your computer's memory, Python will take care of it. Integer numbers can be positive, negative, and 0 (zero). They support all the basic mathematical operations, as shown in the following example:

>>> a = 14>>> b = 3>>> a + b  # addition17>>> a - b  # subtraction11>>> a * b  # multiplication42>>> a / b  # true division4.666666666666667>>> a // b  # integer division4>>> a % b  # modulo operation (reminder of division)2>>> a ** b  # power operation2744

The preceding code should be easy to understand. Just notice one important thing: Python has two division ...
