Answer 1

Ну Были некоторые основные ошибки в коде, json.loads() берет всю правильно отформатированную строку JSON в качестве входных данных, поэтому нет смысла читать файл по строкам и вызывать json.loads(), если у вас нет допустимых JSON в каждой строке, что здесь не так.

Во-вторых, вы пытались получить доступ к "coordinates" поданным неправильно, если он находится в качестве детей "place". Таким образом, окончательный код может выглядеть следующим образом:

import json 

tweets_data = [] 
tweets_data_path = '/home/anusri/pythonpractice/x.json' 

# Read the whole file at once. 
tweets_content = open(tweets_data_path, "r").read() 

try: 
    tweet = json.loads(tweets_content) 
    tweets_data.append(tweet) 
    print tweet['user']['id_str'] + "," + tweet['user']['name'] + "," + str(tweet["place"]['bounding_box']['coordinates']) 
except Exception as e: 
    print "Exception Caught : ", e
