Operators [Jan. 12, 2012, 2:10 a.m.]
Operators work with one or more objects and can perform tasks such as math, comparison, and inspection.
Math
There are standard operators for arithmetic:
Operator | Description |
+ | Addition |
- | Subtraction |
* | Multiplication |
/ | Division |
% | Modulus Division |
** | Exponent |
Additionally, you can modify a named value and assign the output of an operator to the name in one line with inline assignment operators.
>>> a_number = 1 >>> a_number += 1 >>> a_number 2 >>> a_number *= 8 >>> a_number 16 >>> a_number **= 2 >>> a_number 256 >>> a_number /= 2 >>> a_number 128 >>> a_number %= 3 >>> a_number 2
Assignment
- Run Python commands to add, subtract, multiply and divide numbers from the Python interpreter command line.
- Create simple Python script program to perform numeric calculations and output results (e.g. calculating the area of a rectangle or circle).
