Use Python as a calculator

We are going to try some simple commands in Python. Start an interpreter and wait for the primary prompt, >>>. (It shouldn’t take that long).

Numbers

The interpreter acts as a simple calculator; You can enter an expression and it will write the values.

The syntax is simple: the operators +, -, * and / work as in most languages ​​(for example, Pascal or C); parentheses (()) can be used for grouping. For example:

>>> 2 + 2

4

>>> 50–5*6

20

>>> (50–5*6) / 4

5.0

>>> 8 / 5 # division always returns a floating point number

1. 6

Integers (for example 2, 4, 20) are of type int, those with a fractional part (for example 5.0, 1.6) are of type float.
