Noemi Cabrera - Module Five Lesson One Practice Activity

# Noemi Cabrera # 6 October 2021 # In this lesson, I learned to create forever loops using while(), which can be ended by using # the break keyword. The variables you want use in the code are initialized at the beginning # so that you can use them when you want to increment or decrement their value. The Boolean # operator True is used along with the while() to indicate a forever loop. # I didn't have any major difficulties in this lesson. I made mistakes such as not including the # colon at the end of a condition and indenting incorrectly when defining a function.

# [The while True loop will loop forever the statement that is indented. But since the break # keyword is at the end, the statment does not loop and is displayed 1 time. ] # Review and run code # this example never loops because the break has no conditions while True: print('write forever, unless there is a "break"') break

# [ In this code, the user is asked to guess a number between 1 and 5. If the user enters the # secret number, then it will display an statement saying it's correct one time because break # stops the while condition from repeating forever. However, if the user doesn't guess the secret # number, the else statement will print and the while condition will repeat itself until the user # guesses the number. ] review the NUMBER GUESS code then run - Q. what causes the break # statement to run? number_guess = "0" secret_number = "5" while True: number_guess = input("guess the number 1 to 5: ") if number_guess == secret_number: print("Yes", number_guess,"is correct!\n") break else: print(number_guess,"is incorrect\n")

# [ In this code, the user is asked enter the weather. If the user enters a existing weather, # then a statement indicating what you should wear for that weather appears 1 time because break # stops the while condition from repeating forever. However, if the user doesn't enter a valid # weather, the else statement will print and the while condition will repeat itself until the user # enters a valid weather. ] review WHAT TO WEAR code then run testing different inputs while True: weather = input("Enter weather (sunny, rainy, snowy, or quit): ") print() if weather.lower() == "sunny": print("Wear a t-shirt and sunscreen") break elif weather.lower() == "rainy": print("Bring an umbrella and boots") break elif weather.lower() == "snowy": print("Wear a warm coat and hat") break elif weather.lower().startswith("q"): print('"quit" detected, exiting') break else: print("Sorry, not sure what to suggest for", weather +"\n")

# [ This program asks for user input on a common name. If the name is not alphabetical or is blank, # the code would repeat until the user enters a vaid name that can be used. ] # create Get Name program familiar_name = "" while True: familiar_name = input( "Enter a common name of friends or family: " ).title() if familiar_name.isalpha(): print("Welcome to our group", familiar_name,"!") break else: print(familiar_name, "is not a valid name")

# [ In this code, the votes variable is initialized and assigned the value 3. The value is # added 1 by writing votes + 1. Then the value is added 2 by wrting the short method: # votes += 2. ] review and run example votes = 3 print(votes) votes = votes + 1 print(votes) votes += 2 print(votes)

# Since the variable votes was initialized in the code above, here it's used again. The last value # of the variable was 6. Then 6 is substracted 1 using the short method, which results in 5. print(votes) votes -= 1 print(votes)

# [ In this code using the while condition, the variable seat_count is increased by one repeatedly # until the value becomes greater or equal than 4. The if statemnet contains the keyword break, # which ends the forever loop.] review the SEAT COUNT code then run seat_count = 0 while True: print("seat count:",seat_count) seat_count = seat_count + 1 if seat_count > 4: break

# [ In this while condition, the user is asked to enter a seat type. If the input starts with e, # the code displays a space and a statement indicating there are 0 seats entered. However, if the # answer is either hard or soft, the value of 0 is added 1 repeatedly until the entries are # equal to or greater than 4. If the entry is invalid, it's counted as hard and is also added # 1 repeadtly until it reaches 4.] # review the SEAT TYPE COUNT code then run entering: hard, soft, medium and exit # initialize variables seat_count = 0 soft_seats = 0 hard_seats = 0 num_seats = 4 # loops tallying seats using soft pads vs hard, until seats full or user "exits" while True: seat_type = input('enter seat type of "hard","soft" or "exit" (to finish): ') if seat_type.lower().startswith("e"): print() break elif seat_type.lower() == "hard": hard_seats += 1 elif seat_type.lower() == "soft": soft_seats += 1 else: print("invalid entry: counted as hard") hard_seats += 1 seat_count += 1 if seat_count >= num_seats: print("\nseats are full") break print(seat_count,"Seats Total: ",hard_seats,"hard and",soft_seats,"soft" )

# [ The defined shirt_count function gets user input on the amount of shirts of the size S,M, and # L wanted. The amount of each shirt is added 1 each time, but if the user enters exit, the # loop will break and the number of purchased shirts is displayed. The else statement will display # if the user input is not s,m,l, or exit. ] Create the Shirt Count program, run tests def shirt_count(): s = 0 m = 0 l = 0 while True: data = input("Enter shirt size (S,M,L, or Exit): ").lower() if data == "s": print("Adding a shirt size S") s += 1 elif data == "m": print("Adding a shirt size M") m += 1 elif data == "l": print("Adding a shirt size L") l += 1 elif data == "exit": print("No more shirts added.") print("You purchased\n",s, "Small\n",m,"Medium\n",l,"Large") break else: print("The shirt size you entered is not valid\nTry again") shirt_count()

# [ This updated shirt_count function gets user input on the amount of shirts of the size S,M, and # L wanted. The amount of each shirt is added 1 each time. If the user enters exit, the # loop will break and the number of purchased shirts is displayed along with the subtotal cost of # each shirt size and the total cost of the purchase. The else statement will display if the user # input is not s,m,l, or exit. ] Create the Shirt Register Challenge program, run tests def shirt_register(): s = 0 m = 0 l = 0 while True: data = input("Enter shirt size (S,M,L, or Exit): ").lower() if data == "s": print("Adding a shirt size S") s += 1 elif data == "m": print("Adding a shirt size M") m += 1 elif data == "l": print("Adding a shirt size L") l += 1 elif data == "exit": print("No more shirts added.") print("You purchased\n",s, "Small\n",m,"Medium\n",l,"Large") print() print("Subtotal:\nSmall = $"+str(s*6)+"\nMedium = $"+ str(m*7)+"\nLarge = $" + str(l*8)) print() total = (s*6)+(m*7)+(l*8) print("Total: $"+ str(total)) break else: print("The shirt size you entered is not valid\nTry again") shirt_register()
