To access a value in a python dictionary, you use the square brackets after the variable name, as the following example describes: my_dictionary["my key"] ="Value"print(my_dictionary["my key"]). Issues iterating through JSON list in Python?, You are assuming that i is an index, but it is a dictionary, use: for item in data["​Results"]: print item["Name"].
