loops - Iterating thru a not so ordinary Dictionary in python 3.x

Question

Maybe it is ordinary issue regarding iterating thru a dict. Please find below imovel.txt file, whose content is as follows:

{'Andar': ['primeiro', 'segundo', 'terceiro'], 'Apto': ['101','201','301']}

As you can see this is not a ordinary dictionary, with a key value pair; but a key with a list as key and another list as value

My code is:

#/usr/bin/python

def load_dict_from_file():
    f = open('../txt/imovel.txt','r')
    data=f.read()
    f.close()
    return eval(data)
thisdict = load_dict_from_file()
for key,value in thisdict.items():
    print(value)

and yields :

['primeiro', 'segundo', 'terceiro'] ['101', '201', '301']

I would like to print a key,value pair like

{'primeiro':'101, 'segundo':'201', 'terceiro':'301'}

Given such txt file above, is it possible?

Answer 1

As other folks have noted, that looks like JSON, and it'd probably be easier to parse it read through it as such. But if that's not an option for some reason, you can look through your dictionary this way if all of your lists at each key are the same length:

for i, res in enumerate(dict[list(dict)[0]]):
    ith_values = [elem[i] for elem in dict.values()]
    print(ith_values)

If they're all different lengths, then you'll need to put some logic to check for that and print a blank or do some error handling for looking past the end of the list.
