I'm kind of curious why everyone here seems to want to use IntFlags
and other mixins. The docs themselves say that their use should be
minimized, and tbh I agree with them. Backwards compatiblity can be
maintained by allowing the old value and internally converting it to
the enum. Combinability is
or build it yourself...
def str_count(string, sub):
c = 0
for c in range(len(string)-len(sub)):
if string[c:].startswith(sub):
c += 1
return c
(probably some optimizations possible...)
Or in one line with a generator expression:
def str_count(string, sub):
return sum(string[c:]

I personally would like a feature where instead of doing `from ... import
...` (which imports the specified items into the current namespace), one
could use something along the lines of `import .{ , , ...
}` such that the imported modules/attributes could be accessed as
`.`, etc.

Some library authors get pretty pissy about implicit imports at the root

That's the kind of thing I'm looking for. I've dealt with some library
authors who were highly against importing the root allowing me to access
submodules with hierarchy.

There are two ‘AA’ in ‘AAA’, one starting from 0 and the other starting from 1.
If ‘AA’ starting from 0 is deleted and inserted with ‘BANAN’, ‘AAA’ becomes
‘BANANA ‘.
If ‘AA’ starting from 1 is deleted and inserted with ‘PPLE’, ‘AAA’ becomes
‘APPLE’.
Depending on which one is chosen, ‘AAA’ can

Forcing submodule imports would be the main thing, as at the moment,
you have to choose between repeating the base name multiple times
(once per submodule) or losing the hierarchical namespace.
If the base name is short, there are no problems with repeating it

With a package, having automatic imports forces
I just ran into a similar problem, how to relatively import without binding
the submodule.
Let's say you have this :
myapp/
urls.py
views/
base.py
When you're in urls.py and you want to relatively access Functions from
base.py, you must use the from syntax.
from .views import bas
