bytes()
bytes() is a Python function in the Built-in Functions category. Returns an immutable bytes object. The syntax is bytes(source=b""). Parameters: source — int, iterable, or string. Returns: Bytes object. A typical example: bytes(5) # b"\x00\x00\x00\x00\x00"
bytes([72, 73, 74]) # b"HIJ"
bytes("hi", "utf-8") # b"hi". 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.
