wiki.py

I tried to replicate Kenneth's code from the wiki video in the Date/Time module, and I get an error saying that link is not defined.

# Make a script that accepts a month/day date in whatever format you want that returns a link to 
# wikipedia for that date.

# Be sure to tell the user how to format their data for you.

import datetime

answer_format = '%m/%d'
link_format = '%b_%d'
lin = 'https://en.wikipedia.org/wiki/{}'

while True:
  answer = input("What date would you like? Please use the MM/DD format. Enter 'quit' to quit.")
  if answer.upper() == 'QUIT':
    break

  try:
    date = datetime.datetime.strptime(answer, answer_format)
    output = link.format(date.strftime(link_format))
    print(output)
  except ValueError:
    print("That's not a valid date. Please try again.")

I don't see where you're not using the variable lin in your code loop. Do you mean to use:

output = lin.format(date.strftime(link_format))

I see it, I meant to use link for the web address. That's a typo. I have to stop looking at just the line that is flagged when an error pops up. Often the error starts somewhere else. I will fix it and try again.
