Lists and sets both are built-in data types of Python and they can store collections of elements. However, there are some key differences between them hence, sometimes you would be required to convert list to set. Advertisements A list is an ordered collection of elements so, we can add, ...

(You will see a Python data type that is not ordered in the next tutorial on dictionaries.)Lists that have the same elements in a different order are not the same:>>> a = ['foo', 'bar', 'baz', 'qux'] >>> b = ['baz', 'qux', 'bar', 'foo'] >>> a == b False>>> ...
When working with lists, dictionaries, and sets in Python, it’s essential to understand how to combine them effectively. Lists are ordered sequences of elements, while dictionaries are unordered collections of key-value pairs, and sets are unordered collections of unique elements. Combining these ...

However, sets are unordered collections. The order of items in a set is not maintained. Note how the names in the final list are not in the same order as they appear in the original list. The same code may produce a different order when run again or when using a different Python inter...
A list stores an ordered collection of items, so it keeps some order. Dictionaries don’t have any order. Dictionaries are known to associate each key with a value, while lists just contain values. Use a dictionary when you have an unordered set of unique keys that map to values. Note ...
