In Python, a dictionary is a mutable container model that can store any number of key-value pairs. Each element in the dictionary is made up of a key and a value separated by a colon (:), with each key-value pair separated by a comma (,) and the entire dictionary wrapped in curly braces ({}).<\/p>\n

Some common methods of using a dictionary include:<\/p>\n

    \n
  1. dict.keys(): This method returns all the keys in the dictionary.<\/li>\n
  2. Return all values in the dictionary.<\/li>\n
  3. Return all key-value pairs in the dictionary.<\/li>\n
  4. dict.get(key, default): Retrieve the value corresponding to a key, returning the default value if the key does not exist.<\/li>\n
  5. Update the key-value pairs from another dictionary into the current dictionary.<\/li>\n
  6. dict.pop(key): Remove the specified key and its corresponding value.<\/li>\n
  7. Clear all key-value pairs from the dictionary using dict.clear().<\/li>\n<\/ol>\n

    For example:<\/p>\n

    my_dict = {'name'<\/span>: 'Alice'<\/span>, 'age'<\/span>: 30<\/span>, 'city'<\/span>: 'New York'<\/span>}\r\nprint<\/span>(my_dict.keys())  # \u8f93\u51fa: dict_keys(['name', 'age', 'city'])<\/span>\r\nprint<\/span>(my_dict.values())  # \u8f93\u51fa: dict_values(['Alice', 30, 'New York'])<\/span>\r\nprint<\/span>(my_dict.items())  # \u8f93\u51fa: dict_items([('name', 'Alice'), ('age', 30), ('city', 'New York')])<\/span>\r\nprint<\/span>(my_dict.get('name'<\/span>, 'Unknown'<\/span>))  # \u8f93\u51fa: Alice<\/span>\r\nmy_dict.update({'gender'<\/span>: 'Female'<\/span>})\r\nprint<\/span>(my_dict)  # \u8f93\u51fa: {'name': 'Alice', 'age': 30, 'city': 'New York', 'gender': 'Female'}<\/span>\r\nmy_dict.pop('age'<\/span>)\r\nprint<\/span>(my_dict)  # \u8f93\u51fa: {'name': 'Alice', 'city': 'New York', 'gender': 'Female'}<\/span>\r\nmy_dict.clear()\r\nprint<\/span>(my_dict)  # \u8f93\u51fa: {}<\/span>\r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
