1. simple list.py

foods = ["Sushi", "Tacos", "Pizza", "Vegetable Soup"]
print(foods[2]) #Pizza


import random 
cards = ["TEN", "JACK", "QUEEN", "KING", "ACE"]
card = random.choice(cards)
print(card)


population = [1,2,3,4,5,6,7,8,9]
sample_of_three = random.sample(population, 3)

#print each element in list:
for each in sample_of_three:
    print(each)

2. append or pop.py

foods = ["Sushi", "Tacos", "Pizza", "Vegetable Soup"]

foods.append("Brussel Sprouts")

removal = foods.pop(2)

print(removal) #Pizza

print(foods) #['Sushi', 'Tacos', 'Vegetable Soup', 'Brussel Sprouts']

3. lists.py

colours = ['red', 'blue', 'green', 'yellow']
print(colours) #whole list
print(colours[0]) #red
print("Number of elements in list: ", len(colours)) #4
for colour in colours: #each item in list
    print(colour) #print each item

#------------------------------------------- 
days_in_sentence = "Monday Wednesday Friday"

#create list from string:
days_list = days_in_sentence.split()

#appending or changing an element:
print(days_list[-1]) #show last element in list
days_list.append("Saturday")
print(days_list[-1]) #show last element in list now

print(days_list[-1])

4. lists removing items.py

sushi = ['chicken', 'salmon', 'tofu', 'tuna']

#print all items:
for counter, sushiType in enumerate(sushi):
    print("Item number on menu:", str(counter))
    print("Sushi type:", sushiType)

sushi.remove('tofu') #removes first matching value (not specific index)
print(sushi)
#['chicken', 'salmon', 'tuna']

del sushi[2] #deletes item at index 2
print(sushi)
#['chicken', 'salmon']

myfave = sushi.pop(1) #removes the item at a specific index - and returns it
print(myfave) #salmon

print(sushi)
#['chicken']

5. nested list.py

#using a list of lists for a 3 x 3 grid:
nestedList =[["~" for x in range(3)] for y in range(3)]
nestedList[0][2] = "miss"
nestedList[1][0] = "hit"
#dont need to understand this yet:
print("\n".join(''.join(*zip(*row)) for row in nestedList))

1. Ask the user to input 3 foods. Create a list from the 3 foods using append()


2. from your list of 3 different types of food, ask the user for their favourite. pop this food out of the list and return it to the user as output. print the remaining items in the list.


3. We can input values into Python until the user enters an empty line, such as:
   

   movie = input('What movie have you watched? ') 
   while movie != '':

   Continuing this program, use the list append() function to create a unique list of movies the user has seen. You can check if a movie has been duplicated by using if and in together. When the list is complete, print it out in reverse alphabetical order.


4. You are creating a list of outstanding employees. For each month of the year, append the first name of the "employee of the month" to the list. Make sure your favorite employee Benedict appears at least 3 times in the list. Once you have created the list, count the number of times Benedict appears in the list. Your program may look like this when it is run:
   

   employee award month 1: Sarah
   employee award month 2: Jane
   employee award month 3: Benedict
   employee award month 4: Louise
   employee award month 5: Jane
   employee award month 6: Benedict
   employee award month 7: Thomas
   employee award month 8: Benedict
   employee award month 9: Andrew
   employee award month 10: Rita
   employee award month 11: Hakeem
   employee award month 12: Benedict
   number of Benedict awards: 4



5. Adjust your answer to the previous question to allow me to choose who I search the awards for:
   

   employee award month 1: Sarah
   employee award month 2: Jane
   employee award month 3: Benedict
   employee award month 4: Louise
   employee award month 5: Jane
   employee award month 6: Benedict
   employee award month 7: Thomas
   employee award month 8: Benedict
   employee award month 9: Andrew
   employee award month 10: Rita
   employee award month 11: Hakeem
   employee award month 12: Benedict
   Enter employee to count awards for: Jane
   number of Jane awards: 2
