Python 101

1. Which of the following makes the character shoot 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()
  

2. The following two pieces of code do the same thing:

        if condition :
            forward()
        
                # next code

        if condition :
            forward()
         else :
            fire()
        

• True
• False

3. You are given three variables, A=True, B=False and C=False. What is the value of the expression A and ( B or C )?

• True
• False
• None
• I don't know

4. 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

5. 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

6. There is no difference between an "if" statement and an "if-else" statement.

• True
• False

7. A conditional, "if" or "if-else" statement, checks the condition and executes the code in the if-statement if the condition evaluates to true.

    if condition :
        # execute code here
    

• True
• False

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

    if condition1 :
        function1()    
    if condition2 :
        function2()
    
        # next code

    if condition1 :
        function1()
    elif condition2 :
        function2()
    

• True
• False

9. 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

10. 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

11. What is the output of this code?

    x = 2
    if (x > 0) :
        print(“hello”)
    else
        print(“goodbye”)
    
    print(“world”)

• hello
  

• world
  

• 

  hello
  world
  

• goodbye
