bytearray.rpartition

bytearray — split and join

Split at the last separator into a triple.

Syntax

ba.rpartition(...)

The result is always a 3-tuple, so head, sep, tail = ba.rpartition(b'=') can never fail to unpack. When the separator is absent, though, it is the first two parts that come back empty and the original content that lands in the third — the mirror image of partition. Test the middle element to decide whether a match happened; never rely on tuple length or on head being non-empty.

Examples

print(bytearray(b'a=b=c').rpartition(b'='))   # → (bytearray(b'a=b'), bytearray(b'='), bytearray(b'c'))
print(bytearray(b'a=b=c').partition(b'='))   # → (bytearray(b'a'), bytearray(b'='), bytearray(b'b=c'))
print(bytearray(b'key: value').rpartition(b': ')[2])   # → bytearray(b'value')
print(bytearray(b'/usr/local/bin').rpartition(b'/')[2])   # → bytearray(b'bin')
print(bytearray(b'abc').rpartition(b'='))   # → (bytearray(b''), bytearray(b''), bytearray(b'abc'))
