If statements have to have an else or elif statement: NO The action to take place under an if statement needs to be indented: YES If statements with elif statements need else statements as well: YES

A fellow Python programmer is trying to build a quiz and has created the following code: a = 3 b = 7 result = input("What is a + b?") if result = 10: print("You are correct!") else: print("You are incorrect.") This code is not working. Why?

The if result statement needs to read if int(result) == 10:

What would be the value of result that prints at the end of this code? a = 3 b = 7 c = 5 result = a + b * c print(result)

38

For each of the statements regarding pydoc, indicate a yes if the statement is true and a no if the statement is false

Pydoc is a self-contained executable that can be run from a command-line prompt: NO Pydoc generates documentation on Python methods: YES The proper syntax for pydoc is Python -m pydoc module where module represents the name of a Python modeul: YES

Analyze the following code and then answer yes or no. a = float(input("Enter a number.")) b = float(input("Enter a number to divide by.")) try: print(f"The answer is {a/b}.") except: print("This did not work. Did you try to divide by zero?") else: print("You successfully divided two numbers.") finally: print("Thank you for playing.")

The finally statement will run regardless of which pieces of code above it run: YES Both the try and except parts will run if a = 0: NO The else part will run if a = 0: YES

A junior programmer writes the following code to see how many boxes are leftover after crates have been filled: boxes = 25 crates = 4 leftover = boxes mod crates print(leftovers) The result is an error message. What needs to be done to fix the code?

The mod needs to change to a %

A junior programmer has coded a function to compute the area of a rectangle. The code does not work. Look over the code and choose the two problems with the code: function area(x,y): z = x * y print(z) area (5,10)

The two lines under the function declaration need to be indented AND The function keyword should be replaced with def

You are in the process of writing some code to divide two numbers. You want the result to display so long as there are no errors. If there are errors, you want to display a message indicating that the user wither tried to divide by zero or used an invalid number. Using the drop-down arrows, fill in the missing keywords to make this happen.

a = float(input("Enter a number. "))b = float(input("Enter a number to divide by. ")) try: print(f"The answer is {a/b}.") except: print("This did not work. Did you try to divide by zero?")
