What specific data structure in Python do you use for organizing and storing groups of elements?

To organize and store groups of elements in Python, lists (list), tuples (tuple), sets (set), and dictionaries (dict) are often used.

• List — an ordered mutable collection suitable for storing elements that can be changed.
• Tuple — an ordered immutable collection.
• Set — an unordered collection of unique elements.
• Dictionary — stores key-value pairs, useful for quick access by key.

Example of a list:

fruits = ["apple", "banana", "cherry"]
fruits.append("orange")
print(fruits)  # ['apple', 'banana', 'cherry', 'orange']

Python dictionaries are implemented based on hash tables, providing fast access, insertion, and deletion of elements.
