I made my multiple choice questions based on the material from the first python lesson.

Q1. Consider the following code:

a = 7
b = a + 3
a = 2

What does b equal?

A. 5
B. 10
C. 73
D. a3

Q2. If you have a numpy array, in a variable bats, how would you access the data item at the 5th column, 2nd row?

A. bats[2,5]
B. bats(1,4)
C. bats[1,4]
D. bats[4,1]

• C is the correct answer.
• A is the answer they would get if they were indexing from 1 instead of 0
• B is the answer if they where mixing up round brackets, which call functions, and square brackets which access a element of an iterable.
• D is if they mix up that indexing is [row, column], not [column, row].
