I start off asking the user for their option.

option = int(input("What version would you like? 1? or 2?"))

I then check which option they chose.

if Option == 1:

Now that I know they want option 1, I start by asking which place of element they would like.

  n = in(input("What place element would you like to see?"))

I then initialize two variables: a and b.

  a = 0
  b = 1

I then start the for loop to determine the element.

  for i in range(0,n):
    temp = a
    a = b
    b = temp + b

Now that we know the element, we go to the fancy output. First I determine the foot (one's place) of the number.

  if (len(str(n)) > 1):
    foot = str(n)
    foot = foot[-1]
  else:
    foot = str(n)

Then I need to determine the tens place.

  if (len(str(n)) > 1):
    tens = str(n)
    tens = tens[-2]
  else:     tens = '0'

Now is where the output comes in. I'm going to use the tens place to see if it is a 1, because all teen numbers end in 'th', I will use the foot to determine if the number ends with 'st', 'nd', or 'rd'.

    if (tens == '1'):
      print("The " + str(n) + "th element is " + str(a))
    elif (foot == '1'):
      print("The " + str(n) + "st element is " + str(a))
    elif (foot == '2'):
      print("The " + str(n) + "nd element is " + str(a))
    elif (foot == '3'):
    print("The " + str(n) + "rd element is " + str(a))
  else:
      print("The " + str(n) + "th element is " + str(a))

Now we move on to if they choose the second option, where it just lists all the elements.

elif option == 2:

We're going to start off asking how many elements they would like shown.

  n = int(input("How many elements of the sequence would you like to see?"))

As before, I initialize a and b. This time, I'm going to initialize sequence for output.

  a = 0
  b = 0
  sequence = ""

I now start a for loop that calculates the Fibonacci sequence and then stores it in the variable 'sequence'

  for i in range(0, n):
    temp = a
    a = b
    b = temp + b
    sequence = sequence + str(a) + " "

Then we display all the elements.

  print("The first " + str(n) + " elements are: " + sequence)

Finally, if they enter in an improper choice, inform them before quitting.

else:
  print("Improper choice.")
