Question

我正在尝试制作单词字典。我想将添加的单词保存到字典word中，所以当我再次运行它时，我可以查找添加的单词。

#A DICTIONARY THAT CONTAINS ALL THE TRANSLATED WORDS
word = {"ikkje": "ikke"}

#TAKES INPUT FROM USER; THE WORD IN THE FIRST "LANGUAGE"
nynorsk = input("WRITE THE 'NYNORSKE' WORD NOW:") 

bokmål = input("WRITE THE SAME WORD IN 'BOKMÅL' NOW:")

#A FUNCTION THAT ADDS A NEW WORD WITH TRANSLATION TO THE DICTIONARY "word"
def add_word(self,var):
    word[nynorsk] = bokmål

add_word(nynorsk, bokmål)
print(word)

Answer 1

您必须将字典保存到文件中。我建议您使用JSON。

import json

#A FUNCTION THAT ADDS A NEW WORD WITH TRANSLATION TO THE DICTIONARY "word"
def add_word(nynorsk_word, bokmål_word):
    word[nynorsk_word] = bokmål_word

#A DICTIONARY THAT CONTAINS ALL THE TRANSLATED WORDS
try:
    # Try to load the word JSON file.
    word = json.load(open("word.json"))
except FileNotFoundError:
    # Initialize it, if the file does not exist.
    word = {"ikkje": "ikke"}

#TAKES INPUT FROM USER; THE WORD IN THE FIRST "LANGUAGE"
nynorsk = input("WRITE THE 'NYNORSKE' WORD NOW:")
bokmål = input("WRITE THE SAME WORD IN 'BOKMÅL' NOW:")

add_word(nynorsk, bokmål)

# Write the word JSON file.
with open("word.json", "w") as wordfile:
    json.dump(word, wordfile)

print(word)

Answer 2

如果您希望在关闭并打开程序后仍然保留字典，我可能会建议两种方法。

1-您可以使用shelve模块。此模块可帮助您将变量（甚至文件对象）存储到文件中，然后您可以读取文件。

import shelve

shelf = shelve.open('store')
shelf['ikkje'] = 'ikke'

再次关闭并打开文件

import shelve

shelf = shelve.open('store')
print(shelf['ikkje'])
# ikke

2-您可以使用pprint.pformat将变量排列为有意义的格式并将其保存到 .py 文件中。之后只需导入此文件你准备好了。请注意，您只能将此方法用于特定对象，而不能使用文件等复杂对象。

import pprint

words = {'ikkje': 'ikke'}

with open('store.py', 'w') as store:
    store.write('words = ' + pprint.pformat)

再次关闭并打开文件

import store
print(store.words)

# {'ikkje': 'ikke'}

Answer 3

您可以使用pickle在本地磁盘上存储文件。它用于序列化和反序列化

temp = get_list_from_pickle('alerted_dict.pickle')
word = {"ikkje": "ikke"}
#TAKES INPUT FROM USER; THE WORD IN THE FIRST "LANGUAGE"
nynorsk = input("WRITE THE 'NYNORSKE' WORD NOW:") 
bokmål = input("WRITE THE SAME WORD IN 'BOKMÅL' NOW:")

#A FUNCTION THAT ADDS A NEW WORD WITH TRANSLATION TO THE DICTIONARY "word"
def add_word(self,var):
    word[nynorsk] = bokmål
add_word(nynorsk, bokmål)
with open('alerted_dict.pickle', 'wb') as fp:
     pickle.dump(temp, fp)
print(word)

def get_list_from_pickle(filename):
    try:
      with open(filename, 'rb') as fp:
           return pickle.load(fp)
    except FileNotFoundError:
      with open(filename, 'wb') as fp:
           pickle.dump([], fp)

保存字典并坚持下去
