Other variable types

In the previous exercise, you worked with two Python data types:

int, or integer: a number without a fractional part. savings, with the value 100, is an example of an integer.
float, or floating point: a number that has both an integer and fractional part, separated by a point. growth_multiplier, with the value 1.1, is an example of a float.

Next to numerical data types, there are two other very common data types:

str, or string: a type to represent text. You can use single or double quotes to build a string.
bool, or boolean: a type to represent logical values. Can only be True or False (the capitalization is important!).

Create a new string, desc, with the value "compound interest".
Create a new boolean, profitable, with the value True.
