A gzip (.gz) file typically contains a single member, but as per RFC 1952 it can contain many members.

2.2. File format

A gzip file consists of a series of "members" (compressed data sets)

GNU gzip and Apple gzip both appear to decompress multiple members to a single output file.

Demo

1. Create some test files

# A minimalist integer ID type that intentionally doesn't support mathematical
# operations. Subclass it to make e.g. UserID type, FileDescriptor type

class ID(object):
    __slots__ = ('_v',)
    def __init__(self, v):
        if not isinstance(v, int):
            raise TypeError('int required, got: %s"' % type(v))
        if v < 0:
            raise ValueError('cannot be negative', v)
