mybill()
以上是我的代码。你会注意到我有一个名为mybill的函数。我需要有人向我解释如何将账单的输出存储在一个文件中，以便餐厅经理可以返回，使用用户输入来输入日期，并查看他输入的特定日期的所有账单。我不需要存储我的整个代码，我只需要打印账单的每次输出，以便在打印日期之前存储。感谢。

您可以使用python的datetime包作为当前日期和时间
import datetime
now = datetime.datetime.now()
有关其他信息，请参阅here
然后使用python内置的文件管理内容来读取/写入csv文件
receipt_file= open("Receipts.csv", 'a')
receipt_file.write(str(now.year) +',' + str(now.month) + ',' str(now.day) + ',' + str(total_cost))
receipt_file.close()
当你重读它以按用户输入排序时，你甚至可以按年，月和日分开
receipt_file= open("Receipts.csv", 'r')
for line in receipt_file.readlines():
year = line.split(',')[0]
month = line.split(',')[1]
# And so on - maybe even add list of receipts found with given criteria?

您可以打开一个带有附加功能的简单文本文件，并在bill中逐个写入所有字符串，并使用某种命名约定存储该帐单，以便您以后通过传递该名称字符串再次使用您的代码打开该帐单（即账单日期）。 要将代码中的输出写入帐单文本文件，您可以执行以下操作：
方法中有多个print语句。您可以将它们分配给字符串并在终端中打印，然后将它们复制到文本文件中。
def mybill():
with open("bill.txt", "a") as mybillfile:
# use following structure for every print statement
str = " -----Fire n' Fusion------"
myfile.write(str)
print(str)

可能有很多选项可以做到这一点，具体取决于你想要的程度以及你在编程方面的熟练程度。数据库可能是理想的，但您可以使用简单的字典。
使用带日期键的字典：
sales = {date1: {sale1:[], sale2:[]..., date2: {sale1:[], sale2:[]...}
如果您将字典存储为pickle，则可以将其用于代码（根据需要进行修改）。
import pickle
import datetime as dt
# define today's date
heute = dt.date.today()
with open('data.p', 'rb') as fid:
data = pickle.load(fid)
# when adding data to your dictionary
if heute not in data:
data[heute] = {}
# add sale
item = 'soup'
cost = 5.60
quantity = 4
salenum = 'sale' + str(len(data[heute]) + 1)
data[heute][salenum] = {}
data[heute][salenum][item] = {}
data[heute][salenum][item]['cost'] = cost
data[heute][salenum][item]['quantity'] = quantity
# store data to pickle
with open('data.p', 'wb') as fid:
pickle.dump(data, fid)
当您想要每天获得销售时：
with open('data.p', 'rb') as fid:
data = pickle.load(fid)
# specify date of interest
doi = dt.date(2017, 1, 1)
if doi not in data:
print('No sales today!')
else:
for sale in sorted(data[doi]):
for item in data[doi][sale]:
print(item + 'x' + data[doi][sale][item]['quantity'] + ' @ $' + data[doi][sale]['cost'] + ' each')
这只是你可以用字典做的一般概述，应该可以根据你的需要轻松修改。
此代码尚未准备好运行（不要复制/粘贴），它只是一个可行的选项示例（需要调整）。
