list in dictionary python code example

Example 1: python 3.7 insert at place in dict

# Insert dictionary item into a dictionary at specified position: 
def insert_item(dic, item={}, pos=None):
    """
    Insert a key, value pair into an ordered dictionary.
    Insert before the specified position.
    """
    from collections import OrderedDict
    d = OrderedDict()
    # abort early if not a dictionary:
    if not item or not isinstance(item, dict):
        print('Aborting. Argument item must be a dictionary.')
        return dic
    # insert anywhere if argument pos not given: 
    if not pos:
        dic.update(item)
        return dic
    for item_k, item_v in item.items():
        for k, v in dic.items():
            # insert key at stated position:
            if k == pos:
                d[item_k] = item_v
            d[k] = v
    return d

d = {'A':'letter A', 'C': 'letter C'}
insert_item(['A', 'C'], item={'B'})
## Aborting. Argument item must be a dictionary.

insert_item(d, item={'B': 'letter B'})
## {'A': 'letter A', 'C': 'letter C', 'B': 'letter B'}

insert_item(d, pos='C', item={'B': 'letter B'})
# OrderedDict([('A', 'letter A'), ('B', 'letter B'), ('C', 'letter C')])

Example 2: python list of dictionaries

new_player1 = { 'firstName': 'LaMarcus', 'lastName': 'Aldridge', 'jersey': '12', 'heightMeters': '2.11', 'nbaDebutYear': '2006', 'weightKilograms': '117.9'}
            new_player2 = { 'firstName': 'LeBron', 'lastName': 'James', 'jersey': '2', 'heightMeters': '2.03', 'nbaDebutYear': '2003', 'weightKilograms': '113.4' }
            new_player3 = { 'firstName': 'Kawhi', 'lastName': 'Leonard', 'jersey': '2', 'heightMeters': '2.01', 'nbaDebutYear': '2011', 'weightKilograms': '104.3' }  
  
  nba_players = []
  nba_players.append(player)
  nba_players.append(new_player1)
  nba_players.append(new_player2)
  nba_players.append(new_player3)

Example 3: python dictionary with list

dictionary = {"one": [1, 2, 3, 4, 5], "two": "something"}
print(dictionary["one"][2])
