Python has two types of scalar values: numbers and strings. Both types ca be assigned to a scalar variable. Numbers. Numbers are specified in any of the common integer or floating point format: Numbers can also be represented using binary or hexadecimal notations, but we will not need that. Table of the most common number operators in Python:

Most values have built-in operations (like addition, subtration, etc.) that perform calculations on them. Also, one can form sequences of values using lists. Python provides simple built-in facilities for obtaining input from the user. All of these enable us to write not only robot programs but also programs that perform any kind of computation.
