Difference () and []

[macfanpl]

I need to know whats the difference in:

something()

and

something[]

[Gribouillis]

something() applies to objects having a __call__() method and it executes this method, while something[] applies to objects having a __getitem__() method and it executes this method.

Examples of the two cases mentioned by Gribouillis are functions in the former case and lists/dictionaries/tuples in the latter.

Also consider braces {}. A good source to see what you use when is the docs at Python Docs
