Common Nested Dictionary Patterns
# User Profile Structure
'user': {
'profile': {
'name': 'John',
'email': 'john@example.com'
},
'settings': {
'theme': 'dark',
'notifications': True
}
}
Nested Access Patterns
# Direct access:
dict['person']['name']
# Safe access:
dict.get('person', ).get('name', 'Unknown')
# Deep access:
dict['person']['address']['street']
