Yes - introspection can be done by looking at a class's dictionary.

Without knowing any specifics of what you're looking for you can examine
and modifiy object attributes. Python's dynamic nature makes the
modifying part easy (sometimes I think *too* easy :) ).  Along with
dir(), other functions to read a bit on:

type, isinstance, callable, setattr, getattr as well as the attribute
__dict__.

Fwd: Trouble with uninstalling Python 3.8 from windows10

2020-09-22 Thread Malkinson Guy 
Hello 
I'm a Python beginner. I installed last week python 3.8 64bit on windows 10 for 
the purpose of working with tiff images. 
I next tried to import PIL (or pil), but was unsuccessful (all stackoverflow 
solutions didn't work either). I next thought this could be due to the python 
version, and wanted to removed the 3.8 in order to install an older version. 
But I can't seem to uninstall: while the uninstaller gives a "successfully 
uninstalled" message, the python is not removed from the list of programs. I 
also tried deleting the python folder itself, this doesn't work. And of course 
have restarted the computer... 
I then tried to modify via the applications list: I didn't receive the option 
of "modify" or "repair", only install. So I proceeded with the installation, 
which failed , error message 0x80070001 
Any ideas how to solve these issues? 
All the best 
Guy

I find also `help(obj)` very helpful.

The basics behind `help` (a built in function) come from
the `inspect` module. It is very helpful to programmatically inspect
features of Python objects.

Re: Pythonic style

2020-09-22 Thread Stavros Macrakis 
Thanks to everyone for the comments, especially Tim Chase for the simple
and elegant tuple unpacking solution, and Léo El Amri for the detailed
comments on the variants. Below are some more variants which *don't *use
tuple unpacking, on the theory that the coding patterns may be useful in
other cases where unpacking doesn't apply.

For me, one of the interesting lessons from all these finger exercises is
that *for* and unpacking hide a lot of messiness, both the initial *iter* call
and the exception handling. I don't see any way to eliminate the *iter*,
but there are ways to avoid the verbose exception handling.

Using the second arg to *next*, we get what is arguably a more elegant
solution:


_uniq = []
def firstg(iterable):
it = iter(iterable)
val0 = next(it,_uniq)
val1 = next(it,_uniq)
if val0 is not _uniq and val1 is _uniq:
return val0
else:
raise ValueError("first1: arg not exactly 1 long")


But I don't know if the *_uniq* technique is considered Pythonic.

If *next* were instead defined to return a flag (rather than raising an
exception), the code becomes cleaner and clearer, something like this:


def firsth(iterable):
  it = iter(iterable)
  (val0, good0) = next2(it)
  (val1, good1) = next2(it)  # val1 is dummy
  if good0 and not good1:
return val0
  else:
raise ValueError("first1: arg not exactly 1 long")

# returns (value, validp)

# validp is False if no more values

def next2(iterable):
  try:
val = next(iterable)
  except StopIteration:
return (None, False)
  return (val, True)


(To be clear, I'm *not *suggesting that *next2* replace *next*!)

Thoughts?

When doesn't it apply? Can you elaborate on this? It might be easier
to advise on Pythonic style when the specific requirements are known.

In Python, exception handling IS the way to do these things. Having a
two-part return value rather than using an exception is an unusual
idiom in Python (although it's well known in other languages; I
believe JavaScript does iterators this way, for one).

It is when it's needed, but a more common way to write this would be
to have the sentinel be local to the function (since it doesn't need
to be an argument):

def firstg_variant(iterable):
it = iter(iterable)
sentinel = object()
first = next(it, sentinel)
if first is sentinel:
raise ValueError("empty iterable")
second = next(it, sentinel)
if second is not sentinel:
raise ValueError("too many values")
return first

But getting a return value and immediately checking it is far better
spelled "try/except" here. (Note, BTW, that I made a subtle change to
the logic here: this version doesn't call next() a second time if the
first one returned the sentinel. This avoids problems with broken
iterators that raise StopException and then keep going.)

IMO this isn't any better than the previous one. You still need a
sentinel, but now you use True and False instead of a special object.
It isn't *terrible*, but it's no advantage either.

List Partition Comprehension (Feature Suggestion)

2020-09-22 Thread Yakov Shalunov 
Python list comprehension is substantially faster than plan iteration, to the 
point where
```
l0, l1 = [],[]
for x in l:
if cond(x):
l0.append(x)
else:
l1.append(x)
```
runs at about the same speed as
```
l0 = [x for x in l if cond(x)]
l1 = [x for x in l if not cond(x)]
```
assuming `cond` is a computationally light conditional.
While this isn't an extremely common use, I suggest a "partition comprehension" 
syntax which extends normal filtered-generator syntax. Such as:
```
l0, l1 = ([x for x in l if cond(x) else x])
```
(parenthesis there to indicate that the output is a tuple)
It could allow extension to n-way partitions as well. Because elif doesn't fit 
nicely in-line, it would probably be nicer to do it like:
```
l0, l1, l2 = ([x for x in l if cond0(x) else x**2 if cond1(x) else x**3])
```
So l0 would be all elements that match cond0, l1 would be squares of all that 
match cond1, and l2 would be cubes of everything that matches neither.

Re: List Partition Comprehension (Feature Suggestion)

2020-09-22 Thread Yakov Shalunov 
A possible alternative would be a partition library function in the same vein 
as `map` and `filter`
```
def partition(n, key, iter):
"""
Partitions a list.
Args: (n: the number of partitions), (key: function which takes elements 
and returns the index of the partition to place them in), (iter: the iterable 
to be partitioned)
Returns: A tuple of lists partitioned per the key function. If this were a 
library function, this would likely return a tuple of generators instead in the 
same vein as `map` and `filter`.
"""
lists = tuple([] for _ in range(n))
for x in iter:
lists[key(x)].append(x)
return lists
```
Except it would be optimized like a library function (which means written in C, 
I believe)

In addition to the `dir()` that others have mentioned, I'll add that 
developing interactively is very common, especially in ipython/jupyter 
sessions or notebooks. With these, you have tab completion or question 
mark documentation.

For example, if you have an instance `myobj` of the class `MyClass`, 
then in an ipython session, typing `myobj.` will open up a list of 
all the methods for objects of `MyClass`. And given an object or 
funcation, appending `?` will bring up the documentation (as given in 
the docstring) for that object or function. This is true even for 
user-defined functions and objects, even if they were defined during the 
same interactive session.

Good luck!

This syntax seems a bit convoluted. One of the result expressions
is at the beginning as usual, but the rest are tacked on the end.
And it's far from obvious that it returns multiple lists instead
of a single list with alternative values, as you would get from

[(x if cond0(x) else x**2 if cond1(x) else x**3) for x in l]

which at first glance seems very similar.

Also I'm not sure how this would interact with the existing
comprehension syntax in its full generality, where you can
have multiple "for" and "if" clauses mixed in any order.


A possible alternative would be a partition library function in the
same vein as `map` and `filter`

That sounds like a much better idea for something that is so
rarely needed. Although it probably wouldn't be as fast as an
LC could potentially be, due to the need to call a user-supplied
function for every item.

 Well, that file name scares me...

 __main__ is the name Python uses internally for the, well, main program

if __name__ == "__main__":

where imported files will appear with the name by which they were imported.



In a package, __main__.py does that same job.


I am not sure of your intended meaning.

Assume that director 'mypac' is in a directory on sys.path.  Forget 
namespace packages, which I have not studied.

'import mypac' within code imports mypac/__init__.py
'python -m mypac' on a command line runs mypac/__main__.py

Example: .../pythonxy/lib/idlelib. lib is on sys.path.
idlelib/__init__.py is nearly empty.
idlelib/__main__.py starts IDLE,
so 'python -m idlelib' on a command line starts idle.

Parentheses only make a tuple when empty.  They otherwise group items as 
function arguments or to indicate precedence.


'else' by itself would be enough to indicate that one wants two streams, 
even if it is a bit baroque.


'x for x in iterable if condition' is a generator comprehension. 
Putting {} or [] around it says to run the iteration to make a set or 
list.  Passing the generator comprehension to set() or list() has the 
same effect, but the set or list comprehensions can be optimized to run 
faster.


'x:f(x) for x in iterable' is not quite legal as a standalone generator, 
but '(x,f(x)} for x in iterable' is, and {x:f(x) for x in iterable} has 
the effect of

dict((x,f(x)) for x in iterable).

By analogy,
'ftrue(x) for x in iterable if condition else ffalse(x)'
should be a double generator comprehension producing a pair of generators
'(f(x) for x in iterable if condition),
 (f(x) for x in iterable if not condition)'

Then enclosing in {} or [] applies set() or list() to each separately to 
produce a pair of sets or lists.  But the latter could be optimized.


The double generator comprehension is similar to a conditional 
expression except that both true and false values are produced -- and 
kept separate.

'(ft(x) if condition else ff(x)) for x in iterable'
is legal today, but does not separate the true and false results.
