• This would fail as it is a syntax error

Q1. 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?

• Indent the line below the if statement
• Underline all of the conditional code
• Begin the statement with a curly brace {
• Start the statement with a “#” character

Q2. Which of these operators is not a comparison / logical operator?

• ==
• <
• !=
• >=
• =

Q3. What is true about the following code segment:

1. if x == 5 :
2. print('Is 5')
3. print('Is Still 5')
4. 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.

Q4. When you have multiple lines in an if block, how do you indicate the end 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
• You omit the semicolon ; on the last line of the if block
• You capitalize the first letter of the line following the end of the if block
• You use a curly brace { after the last line of the if block

Q5. You look at the following text:

1.if x == 6 :
2.    print('Is 6')
3.    print('Is Still 6')
4.    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?

• You have mixed tabs and spaces in the file
• 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 thinks ‘Still’ is a mis-spelled word in the string
• Python has reached its limit on the largest Python program that can be run

Q6. 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?

• iterate
• break
• except
• else

Q7. What will the following code print out?

1. x = 0
2. if x < 2 :
3. print('Small')
4. elif x < 10 :
5. print('Medium')
6. else :
7. print('LARGE')
8. print('All done')

• Medium All done
• Small All done
• Small Medium LARGE All done
• Small

Q8. For the following code,

1. if x < 2 :
2.    print('Below 2')
3. elif x >= 2 :
4.     print('Two or more')
5. else :
6.    print('Something else')

What value of ‘x’ will cause ‘Something else’ to print out?

• x = 2.0
• This code will never print ‘Something else’ regardless of the value for ‘x’
• x = 2
• x = -2

Q9. 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
• 5
• 2
• 4

Q10. For the following code:

1.astr = 'Hello Bob'
2.istr = 0
3.try:
4.    istr = int(astr)
5.except:
6.    istr = -1

What will the value be for istr after this code executes?

• It will be the ‘Not a number’ value (i.e. NaN)
• It will be a random number depending on the operating system the program runs on
• false
• -1

• There should be no colon on the while statement
• while is not a Python reserved word

Q2. What does the break statement do?

• Exits the program
• Resets the iteration variable to its initial value
• Exits the currently executing loop
• Jumps to the “top” of the loop and starts the next iteration

Q3. What does the continue statement do?

• Exits the currently executing loop
• Jumps to the “top” of the loop and starts the next iteration
• Resets the iteration variable to its initial value
• Exits the program

Q4. What does the following Python program print out?

• 15
• 0
