Based on the SWC lesson Creating Functions
Question 1
Consider the following piece of Python code:
x = 2 n = 3 def poly(x): # Compute simple polynomial value for x n = 2 return x**n print poly(4), x
What two pairs of numbers will be printed out by the above piece of code?
a) 4 2
b) 16 2
c) 4 4
d) 16 4
e) None of the above
Question 2
A student was assigned the following task: Write a function named square that accepts a single argument and returns the square of its argument. Test it by calling it with an argument value of 3, i.e., square(3) and ensure that it returns 9
The student produced the following code:
def square(x): n = 2 x = 3 return x**n print square(3)
However, the above function definition is not correct, e.g., square(2) produces the wrong answer. Correct the function definition by making minimal changes to the code.
