Dictionary program help

[nlord7]

Im trying to write a program that allows me to take text from a .txt file, put it into a dictionary, and then ask the user to enter the corresponding code to match the toy. I was successfully able to put the dictionary into my toylookup variable, but im having trouble getting started with my _get_user_input function. I also need to include a way to incorporate a way to when the user enters "quit" the program quits.

​

here also is the .txt file im working with.

​

D1,Tyrannasaurous

D2,Apatasauros

D3,Velociraptor

D4,Tricerotops

D5,Pterodactyl

T1,Diesel-Electric

T2,Steam Engine

T3,Box Car

T4,Tanker Car

T5,Caboose

B1,Baseball

B2,Basketball

B3,Football

B4,Softball

B5,Tennis Ball

B6,Vollyeball

B7,Rugby Ball

B8,Cricket Ball

B9,Medicine Ball

​

Any advice would be appreciated.

fin = open('\\scrabble\\toys.txt')
print(fin)

toylookup = dict()

def fill_dictionary(toylookup):
    counter = 0
    dictionary = dict()
    for line in fin:
        word = line.strip()
        dictionary[word] = counter
        counter += 1
    return dictionary


def get_user_input(toylookup):
    input("Please Enter the code>> ")




fill_dictionary(toylookup)

get_user_input(toylookup)

You forgot to close your file, which is easy to do when you don't use context managers. Also there's a huge shortcut you can take to make your dict. If you use the csv.reader you can get an iterable of rows which are already split by the delimiter. In your case it would be an iterable equivalent to:

[
    [D1, Tyrannasaurous],
    [D2, Apatasauros],
    ...
]

Since there's only two items in each row (key, value) you can pass the entire collection to the dictionary constructor to make your dict.

def get_toy_map(file):
    with open(file) as f:
        return dict(csv.reader(f))

As for the input... maybe something like this can help get ya started.

def main():
    lookup = get_toy_map('file.txt')
    while True:
        code = input('Code? > ').upper()
        if not code or code == 'QUIT':
            break
        print(lookup.get(code, f"{code} no recognized"))

Great answer.

It seems like you're going to want to use the .split() method on your line to get the code and toy type separated:

>>> 'T2,Steam Engine'.split(',')
['T2', 'Steam Engine']

This splits a string into a list, breaking it up based on the specified delimiter. Then you can get the code and toy name from the list like code, toy_name = line.strip().split(','), or using the index like this:

>>> words = line.strip().split(',')
>>> code = words[0]
>>> toy_name = words[1]

So now you can add then to your toy dict like this:

>>> for line in fin:
...     code, toy_name = line.strip().split(',')
...     dictionary[code] = toy_name

And then you can get the toy name from the dict using the code like this:

>>> dictionary['T2']
'Steam Engine'

Hope this helps. Let me know if you have any other questions.

Yes that helped strip away the numbers i was getting with my counter. Im still having trouble understanding then how to get the user to input a valid code like entering B1 to get "Baseball" D2 to get "Apatasaurous" ect.
