Question

所以，如果我有以下代码：

database = []
Name = input("What's the members name?")
MT = input("What membership type?")
DOB = input("What is the member DOB?")
DJ = (now.day ,"/" , now.month, "/", now.year)
year1 = int(now.year)
month1 = int(now.month)
day1 = int(now.day)
ry = int(year1 + 1)
rm = month1
rd = day1
renewal = (day1, month1, year1 + 1)
details = ["Name:",  Name, "Membership Type:", MT, "Date of Birth:", DOB, "Date Joined:", DJ,"Renewal Date:", renewal, "Renewal Year:", ry]
database.append(details)
menu()

我如何保存（数据库）文本文件/ csv文件以便稍后阅读我尝试过泡菜，但问题是我需要能够将阵列的每个部分分开例如，如果我输入：

print(database[1])

我将返回存储为“Name”的所有名称，但是如果我在将其带回来时使用pickle写文件

print (database[1])

现在显示添加的第二个用户的全部内容。我需要能够保存（数据库）并在读回时以相同的格式使用它。使用JSON或Pickle的预期输出（假设第一个用户输入的名称为“Jeff”，第二个输入的名称为“John”）

print (database[1])

Jeff
John

实际输出：

["Name:",  John, "Membership Type:", MT, "Date of Birth:", DOB, "Date Joined:", DJ,"Renewal Date:", renewal, "Renewal Year:", ry]

很抱歉我不熟悉python。

您似乎正在创建一系列记录。尝试以这种方式访问数据：

print(database[0][1])    #[0] for the first record, [1] for second item
print(database[1][1])    #second user, second item

Python - 将数组写入csv / txt，然后阅读
