1. A "for" loop is typically used when the number of loop cycles is known.

(:div id=q1a:)

Correct. Use a "for" loop to cycle through a specified number of times.

(:divend:)

(:div id=q1b:)

Incorrect. Use a "while" loop when the number of cycles is based on a condition, not number of cycles.

(:divend:)

2. To skip an individual cycle of a for loop, the following command is used:

(:div id=q2a:)

Incorrect. break terminates the loop

(:divend:)

(:div id=q2b:)

Correct. continue initiates the next cycle of the loop

(:divend:)

(:div id=q2c:)

Incorrect. Use a "continue" statement

(:divend:)

(:div id=q2d:)

Incorrect. Use a "continue" statement

(:divend:)

3. What will the following code print as a result for sum?

(:source lang=python:) sum = 0 for i in range(5):

   if i==3:
      continue
   sum = sum + i

print(sum) (:sourceend:)

(:div id=q3a:)

Incorrect. Skip the 3 for 0+1+2+4 = 7

(:divend:)

(:div id=q3b:)

Incorrect. Skip the 3 for 0+1+2+4 = 7

(:divend:)

(:div id=q3c:)

Correct. Skip the 3 for 0+1+2+4 = 7

(:divend:)

(:div id=q3d:)

Incorrect. Skip the 3 for 0+1+2+4 = 7

(:divend:)

4. Which of the following are valid functions in Python?

(:source lang=python:)

1. A

def square_me(x)

   return x^2

1. B

def square_me(x)

   return x**2

1. C

function square_me(x)

   return x**2

1. D

function square_me(x) :

   return x^2

1. E

def square_me(x) :

   return x**2

(:sourceend:)

(:div id=q4a:)

Incorrect. There are 2 problems: no ":" and x^2 should be x**2

(:divend:)

(:div id=q4b:)

Incorrect. No, there needs to be a ":" at the end of the first line

(:divend:)

(:div id=q4c:)

Incorrect. The keyword is "def" not "function", and we need a ":"

(:divend:)

(:div id=q4d:)

Incorrect. The keyword is "def" not "function"

(:divend:)

(:div id=q4e:)

Correct.
