Python’s implementation of an associative array data structure is dictionaries. A dictionary is a collection of key-value pairs. Each key pair is represented by a key pair and its associated value.<\/p>\n
A dictionary is defined by a list of key-value pairs enclosed in curly braces and separated by commas. Each key’s value is separated by a comma in column ‘:’.<\/p>\n
A dictionary cannot be sorted solely for the purpose of obtaining a representation of the sorted dictionary. Dictionaries are orderless by definition, but other types, such as lists and tuples, are not. As a result, you require an ordered data type, which is a list\u2014most likely a list of tuples.<\/p>\n
We can solve this type error by using lists.<\/p>\n
The dict.values() function returns a view object, and view objects cannot be indexed. If we try to select elements from it using indexing, we will receive the following error.<\/p>\n
TypeError: \u2018dict_values\u2019 object does not support indexing<\/pre>\nTake a dictionary and fetch all the values of the dictionary and print the first index then we get this error.<\/p>\n

To avoid this error, we can convert the view object dict values to a list and then index it. For example, we can convert the dict values object to a list object and then select an element from it at any index.<\/p>\n
We can convert dictionary values to list easily by using list(given_dictionary_name. values())<\/p>\n
In this case, we convert all of the values from the dictionary to a list and then chose the first element from the list, which is the first value from the dictionary’s first key-value pair.<\/p>\n
Below is the implementation:<\/strong><\/p>\n
# given dictionary\r\ndictionary = {'this': 200, 'is': 100, 'BTechGeeks': 300}\r\n# extracting the values and converting to list\r\ndictvalue = list(dictionary.values())\r\n# printing the dictionary values\r\nprint(dictvalue)\r\nprint('now extracting the first index of dictvalue')\r\n# printing the first index of dictvalue\r\nprint(dictvalue[0])\r\n<\/pre>\nOutput:<\/strong><\/p>\n
