The following code example does a simple calculation to divide two numbers. You want to handle any errors gracefully and ensure that the last print statement always prints, even if there is an error. Choose One... try: except: else: finally: x = float(input("Enter a number. ")) y = float(input("Enter a number to divide by. ")) print(f"The answer is {x/y}.") Choose One... try: except: else: finally: print("Uh oh. Did you enter something besides a number? Did you try to divide by zero?") Choose One... try: except: else: finally: print("You successfully played the division game.") Choose One... try: except: else: finally: print("Thank you for playing.")

try: x = float(input("Enter a number. ")) y = float(input("Enter a number to divide by. ")) print(f"The answer is {x/y}.") except: print("Uh oh. Did you enter something besides a number? Did you try to divide by zero?") else: print("You successfully played the division game.") finally: print("Thank you for playing.")

The goal with this is to show the nearest integer above and below the # (above for the upperBound variable and below for the lowerBound variable) given and have it work when a different number is present. Choose One... import math use math sys.math sampleNumber = 77.4 upperBound = Choose One... math.ceil math.ceiling math.round math.floor (sampleNumber) lowerBound = Choose One... math.ceil math.ceiling math.round math.floor (sampleNumber) print(upperBound) print(lowerBound)

As the math built-in module is being used, the module needs to be imported. That is done on the first line of code. The math.ceil function takes a floating number up to the next whole number. The math.floor function lowers a floating number to its base whole number. A round function would not be efficient here as it would not guarantee the upper and lower integers from the floating number and returned

Open the shirts file in a mode to where it cannot be written to Read the contents of the entire file Print the contents of the entire file Not every line of code is used: shirtFile = open("shirts.txt","a) shirtFileContents = shirtFile.read() for shirtLines = range(shirtFile): print(shirtFileContents) shirtFile = open("shirts.txt","r")

LINE 1: shirtFile = open("shirts.txt", "r") LINE 2: shirtFileContents = shirtFile.read() LINE 3: print(shirtFileContents)

Take a look at the following code example: carLoan = 20000 intRate = .05 licenseFee = 500 totalLoan = carLoan + licenseFee * intRate A user of the app with this code is complaining that the total loan amount is far lower than what is anticipated. What kind of error is taking place here? User Syntax Runtime Logic

A user gets five chances to correctly guess a whole number between 1 and 10. If the user guesses correctly they will get a congratulatory message and the game ends. If not, they get a message thanking them for playing. Choose One... from random import rand from random import randint from random import randrange for i in range(5): guess = int(input("Enter a number between 1 and 10. ")) randNum = Choose One... randrange(0,10) randrange(1,10) randint(1,10) randint(0,10) if guess == randNum: print("We matched!") break else: print("We did not match. Try again")

from random import randint for i in range(5): guess = int(input("Enter a number between 1 and 10. ")) randNum = randint(1,10) if guess == randNum: print("We matched!") break else: print("We did not match. Try again")

The following code example opens a file, reads it and then prints its contents. In the missing code line, indicate what should be done with the file in order to free up memory the file has been using. jacketsFile = open('jackets.txt', 'r') jacketsFileContents = jacketsFile.read() print(jacketsFileContents) Choose One... jacketsFile.close() jacketsFile.end() jacketsFile.close("jackets.txt")jacketsFile.end("jackets.txt")

jacketsFile = open('jackets.txt', 'r') jacketsFileContents = jacketsFile.read() print(jacketsFileContents) jacketsFile.close()

The following code example, as is prints "You have {items} items in stock" instead of the number of items in stock. Using the drop-down arrow, add the symbol needed to get the number of items to print instead of {items}. price = 9.95 items= 15 print( Choose One..."We have {items} items in stock.") f \ % format

price = 9.95 items= 15 print(f "We have {items} items in stock.")

Finish the following code example with the print statement that will return a value of True. a = 5 b = 5.5 c = 7 d = 7.5 print( Choose One... print(a == int(b) and c != int(d)) print(a != int(b) and c != int(d)) print(a != int(b) and c == int(d)) print (a == int(b) and c == int(d)) )

print(a == int(b) and c == int(d)) print(5 == int(5.5) and 7 == int(7.5))
