Add instructions on installing Python 2.7 and Notepad++, perhaps move this into a separate section.

Introduce variables

Introduce 'primitive' types from which other types are built.

string
int
float

Basic math is easy

Explain strong typing

Briefly digress how primitive types internally are represented by binary, very briefly digress into explaining binary, mention other common numbering system -- duodecimal (base-12) of ancient Sumer and India, now used for telling time (24 = 2 parts of 12). TODO -- more reasearch wiki

Explain str

introduce classes

Note that most of other kinds of things use this type, i.e. screen 2-dimensional array of triplet integers (Red-Green-Blue), date/time -- seconds since 1970, or a type with different members, year, month, day, hour minute, second. Come up with an example of methods based on datetime/timedelta class

Introduce functions as stand-alone methods

....

introduce dictionaries as containers without associated functions

.....

Introduce lists

Ordered containers 'without' arbitrary keys. Tuple is immutable list, string is an instance of tuple

Final exercise -- count the number of days since the new year. More in-depth exploration of datetime/timedelta.
