Python:从JSON转储中删除双引号 [英] Python: remove double quotes from JSON dumps

问题描述

我有一个数据库，该数据库以以下格式将行作为列表返回:

I have a database which returns the rows as lists in following format:

data = ['(1000,"test value",0,0.00,0,0)', '(1001,"Another test value",0,0.00,0,0)']

之后，我使用json_str = json.dumps(data)来获取JSON字符串.应用json.dumps()之后，我得到以下输出:

After that, I use json_str = json.dumps(data) to get a JSON string. After applying json.dumps(), I get the following output:

json_str = ["(1000,\"test value\",0,0.00,0,0)", "(1001,\"Another test value\",0,0.00,0,0)"]

但是，我需要以下格式的JSON字符串:

However, I need the JSON string in the following format:

json_str = [(1000,\"test value\",0,0.00,0,0), (1001,\"Another test value\",0,0.00,0,0)]

所以基本上，我想删除周围的双引号.我尝试使用json_str = json_str.strip('"')完成此操作，但这不起作用.然后，我尝试了json_str = json_str.replace('"', '')，但这也删除了转义的引号.

So basically, I want to remove the surrounding double quotes. I tried to accomplish this with json_str = json_str.strip('"') but this doesn't work. Then, I tried json_str = json_str.replace('"', '') but this also removes the escaped quotes.

有人知道实现此目的的方法吗?还是Python中有类似json.dumps()的函数产生相同的结果，但周围没有双引号?

Does anybody know a way to accomplish this or is there a function in Python similiar to json.dumps() which produces the same result, but without the surrounding double quotes?

推荐答案

您正在转储字符串列表，因此json.dumps完全符合您的要求.对于您的问题而言，丑陋的解决方案可能如下所示.

You are dumping list of strings so json.dumps does exactly what you are asking for. Rather ugly solution for your problem could be something like below.

def split_and_convert(s):
    bits = s[1:-1].split(',')
    return (
        int(bits[0]), bits[1], float(bits[2]),
        float(bits[3]), float(bits[4]), float(bits[5])
    )

data_to_dump = [split_and_convert(s) for s in data]
json.dumps(data_to_dump)
