    copied!<p>I am struggling to write/append a dictionary to a text file. Using 'a' my dictionary has the form{'word_one:'definition_one'}{'word_two:'definition_two'}… instead of what I thought I would get ( and wanted) {'word_one:'definition_one','word_two:'definition_two'…}. What am I doing wrongly. Sorry for such a basic question. I thought that I understood dictionaries and writing to text files, but… The code is:</p> <pre><code>import ast import operator def collectDict(): # first initialize your final_dict and dante_dict dictionary final_dict={} with open('/Users/admin/Desktop/Dante Dictionary/experimental_dict.txt','r', encoding = "utf-8") as dic: dante_dict = ast.literal_eval(dic.read())# reads text as a dictionary (dante_dict,final_dict) = define_words(dante_dict,final_dict) # call the define_words function to update your dictionaries # write your dictionaries with open('/Users/admin/Desktop/Dante Dictionary/experimental_dict.txt', 'w', encoding = 'utf-8') as outfile: outfile.write(str(dante_dict)) # writes source dictionary minus newly-defined term with open('/Users/admin/Desktop/Dante Dictionary/trial_dictionary.txt', 'a', encoding = 'utf-8') as finalfile: finalfile.write(str(final_dict)) with open('/Users/admin/Desktop/Dante Dictionary/trial_dictionary.txt', 'r', encoding = 'utf-8') as finalfile: prelim_dict = ast.literal_eval(finalfile.read()) print(prelim_dict) def define_words(dante_dict,final_dict): # your already written function without the initialization (first 3 lines) and file writing part print('There were ', len(dante_dict), ' entries before defining this word') key_to_find = max(dante_dict.items(), key=operator.itemgetter(1))[0] print('The next word to define is ', key_to_find) # show which word needs defining definition = input('Definition ? : ') # prompt for definition final_dict = {} if key_to_find in dante_dict: final_dict.append[key_to_find] = definition del dante_dict[key_to_find] # remove entry from source dictionary once new definition is done print('the end length is : ' ,len(dante_dict)) # check that entry has been removed from source return(dante_dict,final_dict) # you return the dictionaries for the other function </code></pre> <p>The text file that I start with is :</p> <pre><code>{'amico ': 1, "'Segnor": 1, 'volgere': 1, 'spaventate,': 1, "s'avvantaggia": 1, 'livore': 1, 'disposta ': 1, 'pennelli': 1, 'atto': 15, 'Berti': 1, 'atti': 7, 'Gaia ': 1, 'alzato,': 1, 'reda': 2, "d'ossa": 1, 'rede': 1, 'solvesi': 1, 'Dopo': 3, 'amico,': 1, 'Sardi,': 1, 'pastore,': 2, 'sana ': 1,…} </code></pre>
