Python 3.4 - Default Values for Arguments

Functions do things. Functions are made of arguments: "In mathematics, an argument of a function is a specific input in the function, also known as an independent variable. https://en.wikipedia.org/wiki/Argument_of_a_function

If I made a function called amount_of_hits_per_boxer I would need to arguments (name, hits)

The function would look something like this:

def amounts_of_hits_per_boxer(name, hits= 0):
    print(name, hits)

amounts_of_hits_per_boxer('Tyson =', 34)
 
The output would be Tyson = 34. By giving hits a default value of zero, if there is no input for hits, no 34, than we would just get a return of Tyson = 0. If you don't give arguments default values it can mess up our program, simply stated.

def get_gender(sex= 'Unknown'):
    if sex is 'm':
        sex = 'Male'    elif sex is 'f':
        sex = 'Female'    print(sex)

get_gender('m')
get_gender('f')
get_gender()

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
