It appears that "variables" (which contains "all_friends_paginating_after_cursor" ) is a JSON string. One possible way you could do this is convert it into a dict, change the value, then convert it to a string again. Check out this code snippet:

import json
variables = json.loads(a["variables"])
variables["all_friends_paginating_after_cursor"] = "NEW VALUE"
a["variables"] = json.dumps(variables)
