Python Quiz Thursday

November 24, 2014 Leave a comment Go to comments

There will be a short Python quiz on Thursday 27th November. The questions will be of the format “Write a function that…” as in the examples below. You will be expected to use basic constructs such as loops and conditionals but I won’t expect you to remember particular features of the language such as string or list access methods. However, extra information may be given as part of the question to help you answer. Here are some examples of the level of programming I will be expecting.

Loop through a list.
Write a function called “findLargest” that takes a list of numbers and returns the largest number.

def findLargest(lst):
  max = 0
  for itm in lst:
    if itm > max:
      max = itm
  return max

Use basic conditionals (if, elif, else).
Write a function called “biggest” that takes two numbers and returns the larger of the two.

def biggest(a, b)
  if a > b:
    return a
    return b

Keep looping while a condition is true.
Write a function called “echo” that asks the user for input and keeps repeating whatever they type, unless they type “x”, which quits the function.

def echo:
  s = input("Enter something: ")
  while s != "x":
    print("You entered: " + s)
    s = input("Enter something: ")
