This calls the predicate once per element:
def partition(pred, iterable):
t1, t2 = tee((pred(x), x) for x in iterable)
return (x for b, x in t1 if not b), (x for b, x in t2 if b)
It's kind of inefficient though.

Hello!
Do you know if there has been discussions around why is the default argument is
positional only in the dict methods get and pop?
I think
```
d.get(key, default=3)
```
way more readable than
```
d.get(key, 3)
```
specially since max and min builtin functions use default as a keyword a

Its probably just left over from earlier versions of Python when builtin
functions
