1. What do we do to a Python statement that is immediately after an if statement to indicate that the statement is to be executed only when the if statement is true?
  • Underline all of the conditional code
  • Indent the line below the if statement
  • Start the statement with a “#” character
  • Begin the statement with a curly brace {

2. Which of these operators is not a comparison / logical operator?
  • ==
  • <
  • >=
  • = 
  • !=

3. What is true about the following code segment:
if  x == 5 :
print('Is 5')
print('Is Still 5')
print('Third 5')
  • Depending on the value of x, either all three of the print statements will execute or none of the statements will execute
  • The string ‘Is 5’ will always print out regardless of the value for x.
  • The string ‘Is 5’ will never print out regardless of the value for x.
  • Only two of the three print statements will print out if the value of x is less than zero.

4. When you have multiple lines in an if block, how do you indicate the end of the if block?
  • You omit the semicolon ; on the last line of the if block
  • You put the colon : character on a line by itself to indicate we are done with the if block
  • You use a curly brace { after the last line of the if block
  • You de-indent the next line past the if block to the same level of indent as the original if statement

5. You look at the following text:
if x == 6 :
print('Is 6')
print('Is Still 6')
print('Third 6')
It looks perfect but Python is giving you an ‘Indentation Error’ on the second print statement. What is the most likely reason?
  • Python thinks ‘Still’ is a mis-spelled word in the string
  • In order to make humans feel inadequate, Python randomly emits ‘Indentation Errors’ on perfectly good code – after about an hour the error will just go away without any changes to your program
  • Python has reached its limit on the largest Python program that can be run
  • You have mixed tabs and spaces in the file

6. What is the Python reserved word that we use in two-way if tests to indicate the block of code that is to be executed if the logical test is false?
  • break
  • toggle
  • switch
  • else

7. What will the following code print out?
x = 0
if x < 2 :
elif x < 10 :
else :
print('All done')
  • LARGE 

       All done

  • Small 
  • Small


       All done

  • Small

       All done

8. For the following code,
if x < 2 :
print('Below 2')
elif x >= 2 :
print('Two or more')
else :
print('Something else')
What value of ‘x’ will cause ‘Something else’ to print out?
  • x = 2.0
  • x = -2.0
  • This code will never print ‘Something else’ regardless of the value for ‘x’
  • x = 22

9. In the following code (numbers added) – which will be the last line to execute successfully?
(1)   astr = 'Hello Bob'
(2) istr = int(astr)
(3) print('First', istr)
(4) astr = '123'
(5) istr = int(astr)
(6) print('Second', istr)
  • 1
  • 3
  • 2
  • 6

10. For the following code:
astr = 'Hello Bob'
istr = 0
istr = int(astr)
istr = -1
What will the value be for istr after this code executes?
  • It will be a random number depending on the operating system the program runs on
  • -1
  • It will be the ‘Not a number’ value (i.e. NaN)
  • false
