Alphabet List:

alphabet = "abcdefghijklmnopqrstuvwxyz"

alphabetList = []

for i in alphabet:
    alphabetList.append(i)

print(alphabetList)

['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

Alphabet Numbering: While Loop

letter = input("What letter would you like to check?")

i = 0 

while i < 26:
    if alphabetList[i] == letter:
        print("The letter " + letter + " is the " + str(i + 1) + " letter in the alphabet") #adds 1 to the number that is counted by the program to make the number outputted true
    i += 1

The letter a is the 1 letter in the alphabet

Alphabet Numbering System: Count

letter = input("What letter would you like to check?")

for i in alphabetList:
    count = 1 # counting is started at 1 instead of 0
    if i == letter:
        print("The letter " + letter + " is the " + str(count) + " letter in the alphabet")
    count += 1

The letter a is the 1 letter in the alphabet

Number List: While Loop

evens = []
i = 0

while i <= 10:
    evens.append(i)
    i += 2

print(evens)

[0, 2, 4, 6, 8, 10]

Outputting odd numbers:

odds = []
i = 0

while i <= 10:
    odds.append(i + 1) # starts at 1 instead of 0 to give odd numbers
    i += 2

print(odds)

[1, 3, 5, 7, 9, 11]

Number List: For Loop

numbers = [0,1,2,3,4,5,6,7,8,9,10]
evens = []

for i in numbers:
    if (numbers[i] % 2 == 0): 
        evens.append(numbers[i])

print(evens)

[0, 2, 4, 6, 8, 10]

Outputting odd numbers:

numbers = [0,1,2,3,4,5,6,7,8,9,10]
odds = []

for i in numbers:
    if (numbers[i] % 2 == 1): # start at 1 instead of 0 in order to get odd numbers
        odds.append(numbers[i])

print(odds)

[1, 3, 5, 7, 9]

Printing Numbers That Are Multiples of 2 or 5:

numbers = []
newNumbers = []
i = 0

while i < 100:
    numbers.append(i)
    i += 1

for i in numbers:
    if numbers[i] == 0: # skips the number 0, so that the list is from 1 to 100
        pass
    elif numbers[i] % 5 == 0:
        newNumbers.append(numbers[i])
    elif numbers[i] % 2 == 0: # elif makes the code not repeat numbers
        newNumbers.append(numbers[i])

print(newNumbers)

[2, 4, 5, 6, 8, 10, 12, 14, 15, 16, 18, 20, 22, 24, 25, 26, 28, 30, 32, 34, 35, 36, 38, 40, 42, 44, 45, 46, 48, 50, 52, 54, 55, 56, 58, 60, 62, 64, 65, 66, 68, 70, 72, 74, 75, 76, 78, 80, 82, 84, 85, 86, 88, 90, 92, 94, 95, 96, 98]

Challenge

This code segment is at a very early stage of implementation.

What are some ways to (user) error proof this code?
The code should be able to calculate the cost of the meal of the user

Hint:

write a “single” test describing an expectation of the program of the program
test - input burger, expect output of burger price
run the test, which should fail because the program lacks that feature
write “just enough” code, the simplest possible, to make the test pass

Then repeat this process until you get program working like you want it to work.

menu =  {"burger": 3.99,
         "fries": 1.99,
         "drink": 0.99,
         "salad": 4.99,
         "toast": 2.99}
total = 0

#shows the user the menu and prompts them to select an item
print("Menu")
for k,v in menu.items():
    print(k + "  $" + str(v)) #why does v have "str" in front of it?

#ideally the code should prompt the user multiple times
while total < 3:
    item = input("Please select 3 items from the menu")
    print("Item ordered:", item.lower())
    for k,v in menu.items():
        if item.lower() == k:
            print("Your total order is $", menu[item.lower()])
            total = (total + 1)
            break

    if item.lower() != k:
        print("Try choosing your item again.")
        continue

#code should add the price of the menu items selected by the user

Menu
burger  $3.99
fries  $1.99
drink  $0.99
salad  $4.99
toast  $2.99
Item ordered: burger
Your total order is $ 3.99
Item ordered: water
Try choosing your item again.
Item ordered: salad
Your total order is $ 4.99
Item ordered: toast
Your total order is $ 2.99

Hacks

Now is a good time to think about Testing of your teams final project...

What errors may arise in your project?

What are some test cases that can be used?

Make sure to document any bugs you encounter and how you solved the problem.

What are “single” tests that you will perform on your project? Or, your part of the project?

As Hack Design and Test plan action … Divide these “single” tests into Issues for Scrum Board prior to coding. FYI, related tests could be in same Issue by using markdown checkboxes to separate tests.
