Python 101 Final Test

Which of the following makes the character fire if there is an enemy ahead? Mark all that apply.

• if enemy_in_sight() :

  long_jump()

• if not enemy_in_sight() :

  fire()

• if enemy_in_sight() :

  fire()

• if enemy_in_sight() :

  forward()

Which part of a conditional goes after the if keyword and before the colon?

• • The word “if”

• • The word “else”

• • The code to run

  
  

• The condition

When would you use an "if-else" statement over an "if" statement?

• • When you want to stop running code once the condition is false

• When you want to run different code if a condition is false

• • When you want to run code and then check if the condition is true after

  
  

• • They have the exact same function

  
  

The following pieces of code are the exact same in functionality.

• • True

• False

If you wanted to run different code given different conditions, how would you do that?

• 
  

• • Combine all the conditions in one condition using “or”

  
  

• Use “elif” statements

  
  

• • Put everything in the “else” statement

  
  

• • Create two functions

  
  

When running this code, what will the character do if there is an enemy?

if not enemy_in_sight() :

fire()

• • fire

• nothing

• • walk forward

  
  

• • jump

What is the output of this code?

• • hello

• • world

• hello

  world

• • goodbye

How would you write code to make the character move forward until it reaches a gap?

• 
  

• if not is_gap_ahead() : forward()

• 
  while not is_gap_ahead() : forward()

• while is_gap_ahead() : forward()

• if is_gap_ahead() : backward()

Why is this code not good?

while condition :

if condition :

forward()

• • You cannot put a conditional in a loop

  
  

• • There is a redundant check of the condition

  
  

• • The code will infinitely loop

  
  

• • Nothing is wrong with the code

  
  

What would this code do?

i = 0

while i < 10 :

print(i)

i += 1

• • Print out the number 0 once

  
  

• • Print out the number 0 ten times

  
  

• • Print out the numbers 1-10

  
  

• • Print out the numbers 0-9
