Rspberry Pi Unit 5

For my senior project, I have enrolled myself in an online course to learn Python and ultimately use my knowledge to write the program for a Raspberry Pi computer. The goal of this computer will be to function as a digital home assistant much like Apple's Siri or Amazon's Alexa. Thus far, I have enrolled in the online class and completed ten of the thirteen units. The first unit I completed since the last log check was unit three. This unit covered the topics of conditionals and control flow. Conditionals in python are much like conditional statements in regular language. They are meant to provide conditions as to whether or not a computer should run a certain code. For instance, a computer may decide to only run a specific line of code if an input value is greater than 3. The key conditional in this statement is the word "if". Control flow is simply the order in which a computer reads a code, and it can be regulated by conditionals. …show more content…
A function is a piece of code that can be used to represent and modify a larger block of code. Programmers regularly use functions in order to make their codes more efficient and easy to manage. Functions work by encapsulating large blocks of code and then inserting variable statements into specific parts of the block of code so that a programmer can alter an entire block of code with just the Function code. Unit Five covered lists and dictionaries and their place within Python. A list is a structure of data that can be hidden, altered, or reordered. Much as the name suggests it is typically a list of items, that may range from words to numbers to animals. Each separate piece of data in a list has an assigned number value beginning with 0 and increasing by 1. Items within lists are accessed by their assigned number. Dictionaries are much like lists except they are not put into any order and their items are accessed with specific
