Python 3.4 - Array Module

Arrays are much like lists but they are confined to one type of data.  The example linked needs parentheses around the print statements, but you can see below some of the differences between lists and arrays:

import array

a = array.array("B", range(16)) # unsigned charb = array.array("h", range(16)) # signed short
print (a)
print (repr(a.tostring()))

print (b)
print (repr(b.tostring()))

array('B', [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15])
b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'
array('h', [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15])
b'\x00\x00\x01\x00\x02\x00\x03\x00\x04\x00\x05\x00\x06\x00\x07\x00\x08\x00\t\x00\n\x00\x0b\x00\x0c\x00\r\x00\x0e\x00\x0f\x00'

Python 3.4 - Caesar Cipher

Caesar ciphers take a list of values and rotates through them to give them a different value. The program below takes from the alphabet and creates a cipher of the message. It returns many variations of the cipher then returns the actual message. import string import collections def caesar (rotate_string , number_to_rotate_by): upper = collections.deque(string.ascii_uppercase) lower = collections.deque(string.ascii_lowercase) upper.rotate(number_to_rotate_by) lower.rotate(number_to_rotate_by) upper = '' .join( list (upper)) lower = '' .join( list (lower)) return rotate_string.translate( str .maketrans(string.ascii_uppercase , upper)).translate( str .maketrans(string.ascii_lowercase , lower)) my_string = 'This is the message' my_string2 = caesar(my_string , 1 ) for i in range ( len (string.ascii_uppercase)): print (i , "|" , caesar(my_string2 , i)) /Users/mattfassnacht/PycharmProjects/untitled12/venv/bin/pyt

UML - Use Case Diagram

Image
UML stands for unified modeling language. It is used to create a blueprint for a project. A use case diagram is a list of steps needed to reach a goal. Its defines what is required and how those requirements are met. You will narrow down what you have to have. Before you create a use case diagram you need to create a description of the use case diagram. For example the above would look something like this: Use case descriptions includes who the actors are, what the triggers are, and other elements. Beta versions of a project have Shall requirements, should requirements can be done but can be done later. A use case diagram uses stereotypes to represent an element of your system. https://whatis.techtarget.com/definition/use-case-diagram https://www.youtube.com/watch?v=OkC7HKtiZC0
