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,y)

conditionals

Decision making, the "If" statement, it is based on some type of boolean logic or algebra. What is Boolean algebra?

Boolean algebra is the branch of algebra in which the values of the variables are the truth values true and false, usually denoted 1 and 0 respectively.

from Boolean algebra wiki for Python specific Boolean

Test code of boolean logic boolean prints

As we look at dynamic code, variables are not static so the information we set has to be evaluated.

Such as a number value.

if an incoming argument is 5.

we might have statements looking for something less than 4 but if it is equal do something else.

if argument < 4:

print("less than 4")

elif argument == 4:

print("equals 4)

else:

print("greater than 4")
