Calling a function between quotation marks

Question

I'm a beginner in programming and I'm currently trying to call a function between quotation marks.

Here, more precisely, I would like to replace the name in \\"name\\": \\"name\\", with 88. How would I be able to do that with all those quotation marks?

Thanks in advance for your help

import requests

url = "https://api.multiloginapp.com/v1/profile/create"

def descr():
    return 88

querystring = {"token":"xxxx"}

payload = "{\n\t\"generateZeroFingerprintsData\": true,\n    \"name\": \"name\",\n    \"OS\": \"MacOS\",\n    \"platform\": \"MacIntel\",\n    \"browserType\": \"mimic\",\n    \"proxyHost\": \"0.0.0.0\",\n    \"proxyPort\": 0,\n    \"proxyIpValidation\": false,\n    \"proxyType\": \"socks5\",\n    \"maskFonts\": true,\n    \"disablePlugins\": true,\n    \"disableWebrtcPlugin\": true,\n    \"disableFlashPlugin\": true,\n    \"canvasDefType\": \"noise\",\n    \"hardwareConcurrency\": 2,\n    \"langHdr\": \"en-US,en;q=0.8\",\n    \"timeZone\": \"US/Eastern\",\n    \"audio\": {\n        \"noise\": true\n    },\n    \"geolocation\": {\n        \"permitType\": \"block\"\n    },\n    \"mediaDevices\": {\n        \"audioInputs\": 1,\n        \"audioOutputs\": 1,\n        \"videoInputs\": 1\n    },\n    \"webgl\": {\n        \"noise\": true\n    },\n    \"webRtc\": {\n        \"type\": \"block\"\n    },\n    \"shared\": false\n\t},\n}"
headers = {
    'Content-Type': "application/json",
    'Cache-Control': "no-cache",
    'Postman-Token': "xxx
    }

response = requests.request("POST", url, data=payload, headers=headers, params=querystring)

print(response.text)

The way to do what you're directly asking how to do here is to use string formatting. For example, using printf-style formatting , ¹ instead of this:

payload = " … \"name\": \"name\" … "

… do this:

template = " … \"name\": \"%s\" … "
payload = template % (descr(),)

While we're at it, if you put the payload in single quotes, you wouldn't need to escape every " . Even better, if you put it in triple quotes, you wouldn't need to escape all the newlines. See the tutorial section on Strings for details:

template = """{
    \t"generateZeroFingerprintsData": true,
    \t"name": "%s",
    # …
}"""

But you can make things a whole lot easier by not doing any of this. You're trying to build a JSON text representing a dictionary. The easy way to do that is to just create the dictionary and JSON-ify it :

payloadobj = {
    "generateZeroFingerprintsData": True,
    "name": descr(),
    # …
}
payload = json.dumps(payloadobj)

Or, even better, let requests do it for you. Instead of passing data= with a string, pass it json= with a dict, and it automatically JSON-ifies it, and also sets the Content-Type header for you :

payload = {
    "generateZeroFingerprintsData": True,
    "name": name,
    # …
}
# …

response = requests.post(url, json=payload, headers=headers, params=querystring)

(Also, notice that, instead of calling the generic request function and passing POST , which you really only want to do for custom HTTP verbs that requests doesn't know about , I used the simpler post function, as shown in the quickstart docs .)

_{1. In general, the newer braces-based formatting is simpler. Especially in 3.6+, where you can literally call a function inside quotes, just by wrapping it in braces inside an f-string, like `spam = f'eggs = {eggs()}'. But when the string you're trying to create is full of literal braces, but isn't full of literal percent characters, often that's an exception than the "in general".}
