comments

variables

bag_full_of_candy = 5

box = bag_full_of_candy * 5

x = 2

y = 4

data structures

tuple : position =(x,y)

list :

routes = []

routes.append(position)

Note: Latitude is "0" at equator, "90" north pole / "-90" at south pole

dictionary :

fisheries_area = {}

fisheries_area["cod"] = (x …

strings

Python has some really interesting tools to work with strings

strings are groups of letters and/or numbers

blah = "Beam Me Up, Scotty"
blah[0]
blah[:3]
blah[:-2]
blah[::-1]

for loops

Lets start with a "for" loop, you can think of this as number of revolutions; if only one number is used such as 10 as a static number it is very limiting.

for elm in range(10):
    res = elm * 2
    print(res)

A for loop using a single …

getopt

getopt is a library for utilizing command line options. By adding arguments we can extend simple static variables.

As we have worked with Pythagorean expression, all the variables have been static in nature now with we can make a utility that that will take any combination of numbers.

Functions

A function, What is it?

It is away to create re-usable code; something you might use more than once or away of creating blocks of code that are more easily read.

As an example:

A Math function

A print statement

From lesson 1 we saw c = a**2 + b …
