I'm
so
you're
nice
evening,
okay,
I.
B
C
B
B
So
if
there's
just
something
that
I
use
recently
and
the
filmy
wasn't
available
in
Python
and
it
just
seemed
a
big
oversight
for
a
lot
of
people
in
this,
even
a
subfield
of
solar
physics.
That
number
of
us
are
involved
in
so
just
wondering
if
I
do
I
knew
of
any
previous
efforts
or
anything
either
in
some
vital
can
type
I
or
does
anything
like
that.
B
C
A
That's
that's
not
so
good.
No.
C
A
C
C
A
C
C
A
Same
you
should,
in
theory,
get
one
unified.
You
should
get
one
entry
in
that
list
per
client
or
polka
raleys,
maybe
per
query
as
opposed
in
line,
and
so,
if
you,
if
you've
done
time
and
then
wavelength
or
wavelength,
it
will
probably
have
done
two
queries,
which
means
it
will
recalled
vso
route
twice
connect.
A

Three
stewart
ave
answer:
goodie
Stewart
when
I
have
a
default
argument
or
a
function,
but
I
want
the
default
to
be
arranged
hmmm.
It
like
an
NPA
range
kind
of
structure,
yeah.
A
A
So
this
the
same
argument
is
having
empty
lists
as
argument
as
default
arguments
to
functions
cuz
the
list
gets
created
when
the
interpreter
compiles
the
function
or
imports
the
function?
Okay,
which
means
that
it's
persistent,
if
you
call
the
function
twice
and
modify
the
list,
you're
modifying
something
that's
in
global
scope,
so
you
should
make
the
default
argument
none
and
then,
if
the
default
argument
is
none
in
the
function
create
the
list.
D
D
I
understand
the
problem
that
seems
like
it's
an
unfortunate
artifact
of
the
structure.
Then
I
mean
yeah,
because
the
argument
should
be
a
empty
list.
It's
unfortunate,
you
can
have
it
be
an
empty
list
yeah
and
you
just
have
to
cover
that
up
in
the
doc
string
right
say:
oh
so,
when
you
say
a
mind,
it
actually
does
this
mmhmm.
A
D
A
C
A
D
A
C
D
So
if
the
default
arguments
you're
saying
if
it's
an
otter,
creek
instantiates
the
object
that
actually
gets
constructed
as
as
global
that
sticks
around
it,
it
gets
instantiated
as
part
of
the
function
definition
so
like
when
we
say,
for
example,
I'm
looking
at
jack's
PR
for
super
pixel
and
he
has
an
argument
that
has
offset
equal
to
0
0
times
you
pixel.
So
it's
a
Sherpa
units
array
of
0
0.
E
A
C
C
A
A
D
Program
here,
so,
if
you
had
an
array
or
a
list
of
a
strippa
units,
then
you
could
get
screwed
yeah.
B
A
It's
simultaneously
annoying
and
understand
wall
like
when
you
think
about
it.
The
working
round.
It
would
be
like
very
strange
conceptually
right,
because
you'd
have
to
the
function
would
have
to
reinstate
rien
Stan.
She
ate
all
of
its
default
values.
Every
time
it
was
called,
but
do
it
within
the
scope
of
definition
of
the
function
rather
than
the
calling
code.
