allowing it to take multiple divisors, chaining several calls to
divmod() into one.
Pronouncement
This PEP is rejected. Most uses for chained divmod() involve a
constant modulus (in radix conversions for example) and are more
properly coded as a loop. The example of splitting seconds
into days/hours/minutes/seconds does not generalize to months
and years; rather, the whole use case is handled more flexibly and
robustly by date and time modules. The other use cases mentioned
in the PEP are somewhat rare in real code. The proposal is also
problematic in terms of clarity and obviousness. In the examples,
it is not immediately clear that the argument order is correct or
that the target tuple is of the right length. Users from other
languages are more likely to understand the standard two argument
form without having to re-read the documentation. See python-dev
discussion on 17 June 2005.
