Python Operators are:
1. Addition: +
2. Subtraction: -
3. Multiplication: *
4. Division: /
Parentheses can be used for grouping. Try the following scripts (“>>>” is the Python command prompt):
>>> 9+9 [Enter]
18
>>> 3*7
21
>>> (5*4)+3
23
>>> (40-3*8)/4
4
To assign a value to a variable use “=”:
>>> a=4
>>> b=6
>>> a*b
24
Dividing integers will give the answer rounded down to the nearest integer, also known as the floor:
>>> 9/4
2
>>> 9/-4
-3
In order to divide and return a decimal answer, “floating point” form must be used:
>>> 9.0/4
2.25
