Dictionary Built-in Methods

Dictionaries in Python:


Dictionaries in Python are an important data structure used to store data as key-value pairs. They are unordered, mutable, and indexed. This article discusses the features of Python dictionaries and their built-in methods like `len()`, `max()`, `min()`, `pop()`, `clear()`, `items()`, `keys()`, `values()`, and `update()`.

Built-in Methods:
  • len(): Returns the number of key-value pairs.
  • max()/min(): Returns the largest/smallest value from the keys or values.
  • pop(key): Removes a key-value pair from the dictionary and returns the value.
  • clear(): Removes all key-value pairs.
  • items(): Returns all key-value pairs as tuples.
  • keys(): Returns all keys.
  • values(): Returns all values.
  • update(other_dict): Adds another dictionary or key-value pairs to the dictionary.
