     You might want to check out Ordered Dict:

     As others mentioned in the comments, you would get the elements in no particular order because dictionaries are unordered.

     This sample code works:

     from collections import OrderedDict-database = OrderedDict()database = { "key1": {"key10": "value10", "key11": "value11"}, "key2": {"key20": "value20", "key21": "value21"} }

     If you want to print out or access all first dictionary keys in database.values() list, you may use something like this:

     for key, value in database.items(): print value.keys()[0]

     If you want to just access first key of the first item in database.values(), this may be useful:

     print database.values()[0].keys()[0]-

     Hope this helps.

     Assuming your dictionary looks like this (since you said numbers to elements):

     elements = {'2': 'Hydrogen', '8': 'Oxygen'}-

     You can have this piece of code:

     user_input = '2'for key,value in elements.items(): if user_input == key: print value if user_input == value: print key

     You can convert the loop to a method:

     def search_dictionary(user_input, haystack): for key,value in haystack.items(): if user_input == key: return value if user_input == value: return key

     Then use it like this:

     user_input = raw_input('Please enter your search item: ')elements = {'2': 'Hydrogen', '8': 'Oxygen'}result = search_dictionary(user_input, elements)if result: print("The result of your search is {0}".format(result))else: print("Your search for {0} returned no results".format(user_input))

     You can iterate over a dictionary just like you can iterate over a list.

     for item in item_list: for key in item: print item[key]-

     In a sense, you're still mentioning the keys, but you're not referencing them explicitly by their value.

     If you're just interested in the values you can use the values() method:

     for item in item_list: for key in item.values(): print item[key]-

     My preferred way to iterate over dictionaries though is with items, which returns a tuple of key, value pairs.

     for item in item_list: for key, value in item.items(): print key, value-

   • How to access a dictionary value with a list index number in python?

     Top Answer

     Answered Aug 14, 2019 · 1 votes

     the problem is that list1[0] is a dictionary, and when using the way you are doing in a for loop, it'l iterate over the keys of that dictionary

     so in your case, for the first iteration the e variable is of type int with the value 1, in the second iteration it has the value 2.

     so if you want to iterate over the keys, and values of a dictionary you should use

     for key, val in list1[0].items(): print('key: {}, value {}'.format(key, val))
