1.1 Getting into Python

Views 151 Votes 0 Comment 0

Before we dive into Python, let's start with the operators used in Python.

 

Addition

>>> 1 + 2

 

 

 

 

 

Try writing the above and pressing enter. Do you get an answer?

 

 

Subtraction

>>> 50 - 4
46

 

 

 

 

 

Multiplication

>>> 12345678 * 3
37037034

 

 

 

 

 

Computers know that * means multiply. What about division?

 

 

division

/ is division.

 

 

>>> 5000 / 3
1666.6666666666667
>>> 5000 // 3
1666

 

 

 

 

 

 

 

Remainder

To get the remainder, use the % operator. For example, the remainder of 50 divided by 8 is ?

 

>>> 50 % 8
2

 

 

 

 

 

The quotient of 50 divided by 8 is 6 and the remainder is 2, so the result of 50% 8 is 2.

 

 

Finding the quotient and remainder at once

 

>>> divmod(50, 8)
(6, 2)

 

 

 

 

You can also use the divmod() function to calculate the quotient and remainder at once, like this
