如何从双引号中提取文本并将其添加到字符串中？Python3.x

我想提取captchaData和captchaToken的值，并像这样将数据添加到字符串中

session_token_temp = re.search(r'(\"captchaData\":\")(\w*)', 
response_text).group()
session_token = str(session_token_temp)

您可以使用

ast.literal\u eval

代替正则表达式：

extracted_data = (value_of_captchaData)
extracted_data2 = (value_of_captchaToken)

---

如果您只想删除字符串前后的给定字符，可以使用

strip

听起来您实际上要做的是解析JSON。JSON是一种格式，通常用于表示web上的数据

如果您使用的是请求（听起来像来自标记），那么可以使用

.json（）

来解析结果。否则，请使用内置的

json

模块

'"some string"'.strip('"') # 'some string'

或

---

你能给出一个精确的输入和输出的例子吗？这只是偶然的。JSON和python dict格式有点类似，但一旦使用了

null

或

true

之类的格式，就会出现这种情况。我强烈建议您只使用JSON解析器。

r = requests.get("https://httpbin.org/get")
data = r.json()

import json

data = json.loads('"key": "value"')
