Different meanings of brackets in Python

Question

I am curious, what do the 3 different brackets mean in Python programming? Not sure if I\'m correct about this, but please correct me if I\'m wrong:

[] - # No         


        

Answer 1

• []: Used to define mutable data types - lists, list comprehensions and for indexing/lookup/slicing.
• (): Define tuples, order of operations, generator expressions, function calls and other syntax.
• {}: The two hash table types - dictionaries and sets.
