hi, everybody here,
I am a newbie to python. I encounter a problem that how to convert
an array of numarray to pil object. For example, the data in an image
is extracted using Image.getdata, then the data are converted into an
array in numarray. But when the array is needed to convert to the
Thanks. But some problems remain.
I have known using Image.tostring/fromstring and
numarray.tostring/fromstring can do the job. But when confronting
multi-spectral images, e.g., RGB color images, I don't know how to do
it. Could you give some advices on that?
You wrote "In [14]: img = Image.fromb
In Python interactive mode, is there some function acting like 'clear'
command in bash? Could somebody here give some advice?
Thanks in advance.

Sorry, I make the mistakes. I have known how to use to/fromstring
method to interface between PIL and Numarray.
And your code does work.
Another question. Just like the code you provide, is it possible to
directly load image data from PIL to Numarray array without use of
to/fromstring method?
Thank you very much. I have tested it under Cygwin, and that works. But
it fails under Windows Python Shell Mode.

According to pp 134 of "C: A Reference Manual", it's better to use

Hah, I admit I lacked perseverance in looking at this in PyCharms debugger as I
missed
that.
Much appreciated!

I have a dict of lists. I need to create a list of 2 tuples, where each tuple
is a key from
the dict with one of the keys list items.
my_dict = {
'key_a': ['val_a', 'val_b'],
'key_b': ['val_c'],
'key_c': []
}
[(k, x) for k, v in my_dict.items() for x in v]
This works, but I need to t

Right, I overlooked that!

I have some queries that utilize instr wrapped by substr but the old
version shipped in 2.7.5 doesn't have instr support.
Has anyone encountered this and utilized other existing functions
within the shipped 3.6.21 sqlite version to accomplish this?
Thanks,

Sorry guys, forgot about create_function...

Hi,
I have a C++ module where I have a defined, working type. How would I make a
wrapper for this type to be able to be used in Python? I am familiar(-ish) with
the C-API for functions but I can't see concretely how one would include an
interface to a type.
Is it this? http://docs.python.org/r
I have what I think should be a relatively simple question for someone who
is knowledgeable about Python.
At the IDLE prompt, when I enter "b" > 99, it responds True. In fact, it
doesn't matter which number is entered here, "b" is always greater (e.g. "b"
> 1 == True; "b" > 10 == True, or "
Trying to robustly parse a string that will have key/value pairs separated
by three pipes, where each additional key/value (if more than one exists)
will be delineated by four more pipes.
string = 'key_1|||value_1key_2|||value_2'
regex = '((?:(?!\|\|\|).)+)(?:\|\|\|)((?:(?!\|\|\|).)+)(
> Regexes may be overkill here. A simple string split might be better:
Yup, and much more robust as I was looking for.
Thanks everyone!

I get a list of dicts as output from a source I need to then extract various
dicts
out of. I can easily extract the dict of choice based on it containing a key
with
a certain value using list comp but I was hoping to use dict comp so the output
was not contained within a list.
reduce(lambda x,y:
> {k: v for d in my_list if d['key'] == value for (k, v) in d.items()}
Ugh, had part of that backwards:) Nice!

I suppose, what I failed to clarify was that for each l
101 - 200 of 618 matches
