将字典保存为文件的同时保存文件

Question

itemsInExistence = []
item = {}
item['name'] = input("What do you want the new item to be called? ")
item['stats'] = int(input("What is its stat? "))
item['rank'] = int(input("What is its base rank? "))
item['amount'] = int(input("How many of it are there? "))
for i in range(item['amount']):
  itemsInExistence.append(item)
def save_list2():
  with open('itemsleft.txt', 'wb') as f:
  i = 0
  for item in itemsInExistence:
    pickle.dump(itemsInExistence, f)
    i += 1

我试图正常保存它和泡菜，但是都没有保留字典的值。我需要将字典保存到文件中，并从文件中检索“ stats”，“ rank”，“ amount”仍然是整数，并且与该行的其余部分分开。 （请记住，itemsInExistence中将有多个保存的项目，要保存和加载。）

def save_list2():
  ii = 0
  for i in itemsInExistence:
    d = itemsInExistence[ii]
    json.dump(d, open(files2, 'w'))
    ii += 1 

def load_list2():
    with open(files2,'r') as a:
      for line in a:
        line = line.strip()
        itemsInExistence.append(line)

您可以使用JSON格式将字典存储到文件中，这很容易

import json

file = "foofile"
d = dict()
# fill d

# save data : format the dict to a string and it into the file
json.dump(d, open(file, 'w'))

# read data : read the file's content and parse to a dict
a = json.load(open(file))
