我有以下代码段：

input = "You can check it out here. https://www.youtube.com/watch?v=Ay1gCPAUnxo&t=83s I'll send $20 in bitclout to the first 50 people that follow instructions at end of the video. This is revolutionary. Let's hope it works! <3Building it. What's up y'all"

def createJsonText(input):
    input = r'{}'.format(input)
    x = r'{ "text":"' + input + r'"}'
    print(x)
    # parse x as json
    y = json.loads(x)
    f = open("tone.json", "a")
    f.write(str(y))
    f.close()

执行上述代码时，出现以下错误：
文件“hashtag analyzer.py”，第x行，在readjson createjsontext（input）文件“hashtag analyzer.py”中，第y行，在createjsontext y=json.loads（x）file“/library/frameworks/python.framework/versions/3.6/lib/python3.6/json/init.py”中，第354行，在loads return“default\u decoder.decode（s）file”/library/frameworks/python.framework/versions/3.6/lib/python3.6/json/decoder.py”中，第339行，在decode obj中，end=self.raw\u decode（s，idx=\u w（s，0.end（））file“/library/frameworks/python.framework/versions/3.6/lib/python3.6/json/decoder.py”中，第355行，在raw\u decode obj中，end=self.scan\u，idx）json.decoder.jsondecodeerror:应为'，'分隔符：第1行第4194列（char 4193）
如何解决？
预期输出是名为“tone.json”的json文件，其中包含以下数据：

{
  "text": "You can check it out here. https://www.youtube.com/watch?v=Ay1gCPAUnxo&t=83s I'll send $20 in bitclout to the first 50 people that follow instructions at end of the video. This is revolutionary. Let's hope it works! <3Building it. What's up y'all"
