example code:
log = {}
for t in range(5):
for r in range(10):
log.setdefault(r, '') += "test %d\n" % t
pprint(log)
instead, as the above is not possible, the following must be used:
from operator import add
...
...
...
add(log.setdefault(r, ''), "test %d\n" % t)
... ARGH! just checked - NOPE! add doesn't work.
and there's no function "radd" or "__radd__" in the
operator module.
unless there are really good reasons, can i recommend allowing +=
on return result of function calls.
i cannot honestly think of or believe that there is a reasonable
justification for restricting the += operator.
append() on the return result of setdefault works absolutely
fine, which is GREAT because you have no idea how long i have
been fed up of not being able to do this in one line:
log = {}
log.setdefault(99, []).append("test %d\n" % t)
