RE: Dictionary/List Homework - ImLearningPython - Dec-13-2018
Now that I have done that, I'm not sure how to fix this.
Traceback (most recent call last):
File "C:/Users/brand/PycharmProjects/Test/playground/Playground.py", line 22, in <module>
set_title = sorted(set(title_list))
TypeError: unhashable type: 'list'
RE: Dictionary/List Homework - nilamo - Dec-13-2018
Spin up the debugger, and see what
title_list is, to try to find the issue.python -m pdb myfile.py -> # first line of program (Pdb)Then type
next (or just "n") to step through the code until you get to the line that's throwing an error. Once there, type interact, and then print(title_list).If I were to take a guess, though, it's that
title_list is a list of lists, which doesn't make sense to try to make a set out of. Remember, you just changed the structure of your data, so you'll probably need to change some of the code that parses that structure so it'll work with the new structure.

I have a completely working program now with one exception. I can't seem to figure out where the indention error is coming from.

You have a while loop on line 36, but there is nothing in the while loop.

RE: Dictionary/List Homework - ImLearningPython - Dec-14-2018
I am now getting my inside loops to run indefinitely, why?
If I don't have the while loop at the beginning the other loops run as they should and stop. When I add the while and else statement, they run non-stop.
options = input()
while options == 'y' or 'd' or 't':
if options == 'y':
print('\nMENU\nSort by:\ny - Year\nd - Director\nt - Movie title\nq - Quit')
print('\nChoose an option:')
for key in movies:
print('%s:' % key)
i = 0
while i < len(movies[key]):
print('\t%s, %s' % (movies[key][i], movies[key][i + 1]))
i += 2
print()
director_list = []
if options == 'd':

RE: Dictionary/List Homework - ichabod801 - Dec-14-2018
That's because your first while loop's condition is always True. This is what nilamo was saying in his last post. You need to follow the link in that post.
RE: Dictionary/List Homework - ImLearningPython - Dec-14-2018
I'm looking at that link to try and get a better understanding of loops, I struggle greatly with them.
I posted my post when he posted his, I did not see it while I was typing mine. Once I seen it, I went to the link and I'm trying to figure it out.
Thank you for your help. I do enjoy this, slow learner, yet still enjoyable non the less.
RE: Dictionary/List Homework - ImLearningPython - Dec-14-2018
If I am understanding this correctly. In this line of code I would need to change options to something else. Then make options to this in place of 'yes'.
yes = ("Yes", "Y", "yes", "y")
if value in yes:options = input()
while options != 'q':
if options != 'q' or 't' or 'd' or 'y':
while options != 'q' or 'd' or 't' or 'y':
if options == 'y':
print('\nMENU\nSort by:\ny - Year\nd - Director\nt - Movie title\nq - Quit')
print('\nChoose an option:')
for key in movies:
print('%s:' % key)
i = 0
while i < len(movies[key]):
print('\t%s, %s' % (movies[key][i], movies[key][i + 1]))
i += 2
print()
director_list = []
if options == 'd':
print('\nMENU\nSort by:\ny - Year\nd - Director\nt - Movie title\nq - Quit')
print('\nChoose an option:')
for key in movies:
i = 1
while i < len(movies[key]):
director_list.append(movies[key][i])
i += 2
set_director = sorted(set(director_list))
for director in set_director:
print('%s:' % director)
for year, value in sorted(movies.items()):
if director in value:
print('\t%s, %s' % (value[value.index(director) - 1], year))
print()
title_list = []
if options == 't':
print('\nMENU\nSort by:\ny - Year\nd - Director\nt - Movie title\nq - Quit')
print('\nChoose an option:')
for key in movies:
i = 0
while i < len(movies[key]):
title_list.append(movies[key][i])
i += 2
set_title = sorted(set(title_list))
for title in set_title:
print('%s:' % title)
for year, value in sorted(movies.items()):
if title in value:
print('\t%s, %s' % (value[value.index(title) + 1], year))
print()
if options == 'q':
print('\nMENU\nSort by:\ny - Year\nd - Director\nt - Movie title\nq - Quit')
print('\nChoose an option:')
So far I have been able to get the output to be what I want. I just can't seem to get it to loop and offer another input till user inputs q.
RE: Dictionary/List Homework - ichabod801 - Dec-14-2018
You haven't fixed the problem, you just created more of it. Lines 3 and 4 still have the same problem of 'or's without operators. And I'm not sure why they are there anyway. You should have one loop, with a while condition using the in operator. Note that you case-insensitive checks by using lower to lower-case the input. So just make one while loop with
while options.lower() in ('y', 'd', 't'):.
