python dictionary of dictionaries code example

Example 1: how to use dictionaries in python

student_data = {
  "name":"inderpaal",
  "age":21,
  "course":['Bsc', 'Computer Science']
}

#the keys are the left hand side and the values are the right hand side
#to print data you do print(name_of_dictionary['key_name'])

print(student_data['name']) # will print 'inderpaal'
print(student_data['age']) # will print 21
print(student_data['course'])[0]
#this will print 'Bsc' since that field is an array and array[0] is 'Bsc'

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: Nested dictionary Python

IDs = ['emp1','emp2','emp3']

EmpInfo = [{'name': 'Bob', 'job': 'Mgr'},
           {'name': 'Kim', 'job': 'Dev'},
           {'name': 'Sam', 'job': 'Dev'}]

D = dict(zip(IDs, EmpInfo))

print(D)
# Prints {'emp1': {'name': 'Bob', 'job': 'Mgr'},
#         'emp2': {'name': 'Kim', 'job': 'Dev'},
#         'emp3': {'name': 'Sam', 'job': 'Dev'}}

Example 4: dict of dict python

nested_dict = { 'dictA': {'key_1': 'value_1'},
                'dictB': {'key_2': 'value_2'}}

Example 5: Nested dictionary Python

D = {'emp1': {'name': 'Bob', 'job': 'Mgr'},
     'emp2': {'name': 'Kim', 'job': 'Dev'},
     'emp3': {'name': 'Sam', 'job': 'Dev'}}
