One of my responses looks like,
{
"password": [
"Ensure that this field has atleast 5 and atmost 50 characters"
]
}
And I am trying to fetch the string inside password.How I can get it.
Below is the code which I am trying
key = json.loads(response['password'])
print(key[0]),
But it says 'string indices must be integers, not str'
The error message is correct.
key = json.loads(response['password'])
print(key[0]),
The format of json is string. You need to convert the string of a json object to python dict before you can access it.
i.e.: loads(string) before info[key]
key = json.loads(response)['password']
print(key[0])
Usually the json will be a string and you will try and deserialise it into a object graph (which in python are typically are made up of maps and arrays).
so assuming your response is actually a string (eg that was retrieved from a HTTP request/endpoint) then you deserialise it with json.loads (the function is basically load from string), then you've got a map with a 'password' key, that is an array, so grab the first element from it.
import json
resp = '{ "password": [ "Ensure that this field has atleast 5 and atmost 50 characters" ] }'
print json.loads(resp)['password'][0]
