Python 3.4 - Membership and Identity Operators

Membership operators check to see if an object is present. using the in function one can determine if an object exists in a data set.

data = "My name is Matt"
"name" in data
True 
 
You can use is or == to determine if a variable is using the same object reference. You may also use the is not to determine if two variables are using the same object reference.


my_list = ['john', 'matt', 'rick', 'jehovah', 'buddha']
my_list2 = ['john', 'matt', 'rick', 'jehovah', 'buddha']

if 'dog' in my_list:
    print('hello')
else:
    print('not in the list')

    ## the in operator checks to see if the value dog is in the list.

if my_list == my_list2:
    print('they are the same') ## this checks to see if they are the same.

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
