for i in alphabet:

The intended outcome is to determine where the letter is in the alphabet using a while loop
- What is a good test case to check the current outcome? Why?
- Make changes to get the intended outcome.
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")

The intended outcome is to determine where the letter is in the alphabet using a for loop

This code outputs the even numbers from 0 - 10 using a while loop.
- Analyze this code to determine what can be changed to get the outcome to be odd numbers. (Code block below)
evens = []
i = 1
while i <= 10:
evens.append(i)
i += 2
print(evens)
This code should output the odd numbers from 0 - 10 using a while loop.
odds = []
i = 1
while i <= 10:
odds.append(i)
i += 2
print(odds)
This code outputs the even numbers from 0 - 10 using a for loop.

numbers = [0,1,2,3,4,5,6,7,8,9,10]
evens = []
for i in numbers:
if (numbers[i] % 2 != 0):

The intended outcome is printing a number between 1 and 100 once, if it is a multiple of 2 or 5
- What values are outputted incorrectly. Why?
- Make changes to get the intended outcome.

print(newNumbers)
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 = {"travis scott burger": 210834,
"fries": 1.99,
"drink": 0.99,
"filet mingon": 0.01,
"47 dollars gift card": 46}
total = 0
#shows the user the menu and prompts them to select an item
print("What would you like? \n" + "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
# Start of custom code:
byebye = False
while byebye == False:
item = input("Please select an item from the menu")
fail = True
if(item == "bye bye"):
break
for tempItem in menu:
if(item == tempItem):
total += menu[item]
fail = False
if(fail):
print("You cant buy " + item + " ")
else:
print("That will be $" + str(total))
#Tip
print("Ok, how much would you like to tip? 🔫")
tip = input()
if(int(tip)>5):
print("Thank you so much!")
else:
print(":(")
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.
