set()
set() is a Python function in the Built-in Functions category. Creates a set from an iterable, removing duplicates. The syntax is set(iterable=()). Parameters: iterable — any iterable (optional). Returns: Set. A typical example: set([1, 2, 2, 3]) # {1, 2, 3}
set("hello") # {"h", "e", "l", "o"}. A close sibling is print(), which prints objects to the text stream, separated by `sep` and followed by `end`. A close sibling is len(), which returns the length (number of items) of an object. Works with sequences, collections, and strings. A close sibling is range(), which returns an immutable sequence of numbers. Commonly used in for loops. A close sibling is type(), which returns the type of an object, or creates a new type with three arguments.
