Pass parameters/globals to eval
I am trying to set the parameter 'a' below so that it can be used when I call
eval:
def gp_function():
... return 1+a
...
print eval(gp_function(), {'a':123, 'gp_function':gp_function})
Traceback (most recent call last):
File stdin, line 1, in module
File string, line 1, in module
File stdin, line 2, in a_method
NameError: global name 'a' is not defined
Why isn't 'a' defined?
Shouldn't you be able to define the global variables with a dict passed to eval?
Is there an other way to do this, beside the two obvious: defining 'a' before
calling gp_function and using a as an argument in gp_function?
In case you are wondering why I want this:
This is a simplification of a problem I ran into when experimenting with
pyevolve. After running pyevolve: GTreeGP.getCompiledCode() I get some compiled
code, and need to pass some arguments to it. Perhaps there is an easier way to

Is there an other way to do this, beside the two obvious: defining 'a' before calling gp_function and using a as an argument in gp_function? It is defined, but not in the context of the called function. You defined that function in a particular scope, which then becomes its global scope. (I'm handwaving a lot of details here. Bear with me.) When you eval a bit of code, you define the global scope for _that code_, but not what it calls. Calling gp_function from inside there switches to the new global scope and off it goes. Normally, I'd recommend your second option, passing a as an argument. It's flexible, clear, doesn't rely on fancy names and hidden state. But to answer your actual question: Yes, there is another way to do it. In all probability, gp_function is actually defined at module scope (I'm guessing here but it seems likely based on your description). Simply assign to the module's namespace before calling it - it'll see that as a global. ChrisA -- http://mail.python.org/mailman/listinfo/python-list

No. I give an example and explicitly state:
You can use this class without instantiating:
Example.method('else') # returns 'something else'
Then I'd probably use class attributes to store the
default state and shade them by instance attributes as needed.
class A:
state = default
def __init__(self, state=None):
if state is not None:
self.state = state
def method(self): return self.state
That doesn't allow me to call A.method().
On the other hand, if method were a class method, then I could say
A.method() or A(state).method, but in both cases I would get the default.
So that isn't suitable.

The same idea might work for the OP, too (but I'm not sure it's a good
idea):
class B:
This needs to be a new-style class unless you're using Python 3.
def inst_f(self):
return instance
@classmethod
def f(class_):
return class
def __init__(self):
self.f = self.inst_f
assert B.f() == class
assert B().f() == instance
Without studying that in detail, it looks like that would be an
alternative solution to the same problem. The downsides are:
- you have two distinct but almost identical implementations of
method f, one called f and one called inst_f;
- it works by shadowing method f in the instance, which may
strike many people as too tricky for production software.
Me personally, I think the first objection is critical. Having to write
the same method twice, with subtle differences, is inviting bugs.

Re: 10 sec poll - please reply!
Dear all, the emails are getting kind of long so to ask you briefly: What do you think of splitting `type` into two functions `press` and `enter`? Their use cases are: press(CTRL + 'a') press(ENTER) press(ALT + 'f', 's') enter(Hello World!) enter(test.txt, into=File name) Thanks, Michael On Thursday, November 22, 2012 7:00:55 PM UTC+1, Michael Herrmann wrote: Dear all, thank you for your replies. After experimenting with your suggestions, we have arrived at a solution that we believe fits well with our existing API. However, before we implement this solution, we would like to ask you one last time to sign off on our proposal or raise any serious problems you see with it. We took the fact that naming our one function 'type' was so difficult to name as an indicator that it may be trying to do too many things: On the one hand, it allows you to enter plain text as in `type(Hello World!)`; on the other hand, it lets you press single keys, possibly in combination with control keys as for instance in `type(CTRL + 'a')`. We believe it won't normally be necessary to combine the two. For instance, while you could see what type(CTRL + 'a' + Hello World!) does, we think you would be more likely to use the two separate calls type(CTRL + 'a') type(Hello World!) One of the main goals of our automation product is that using it should feel like giving instructions to a human being looking over their shoulder at a screen. For this reason, it's very useful for us if the function names in our API are short, if possible without underscores, and close to the vocabulary you would use in an everyday conversation. We hope that by offering an API with this property, we can not only make it easier to use for experienced programmers such as yourself, but also be approachable for people from a less technical background. In our gut feeling, the words apart from `type` that would most normally be used in an everyday conversation to express the three examples I have given in my first mail are: press(CTRL + 'a') enter(Hello World) press(ENTER) We really quite like the word `type`, and a few people here seem to favour it too. In particular, Steven: We're glad you accidentally clicked on our mail. Thank you for your inputs and the great quote by Phil Karlton. We think you were right in everything you said. However, some people seem to be *really* put off when you override a built-in function. Even though of course you can avoid the overriding by saying from automa.api import type *as* ..., (as Tim pointed out) we'd like to avoid irritating those people. For this reason, we would rather not use `type`. Many people here voted for send_keys(...). We agree with Dave and Neil that `type` may have too many uses already. As Chris and MRAB pointed out, 'send_keys' is used in many other automation tools. This makes it intuitive for people with knowledge of such tools. However, as I said above (and should have probably said earlier), we are also trying to reach users from a less technical background. Since these people would not normally use 'send_keys' in an everyday conversion, we are afraid that it would not be an intuitive name for them. A similar argument applies to some extent to our 'type_keys', to our 'generate_keystrokes', Ramit's 'simulate_keypress', 'simulate_key(s)_down', 'send_kb_press', 'fake_typing' and 'send_char(s)' and Tim's 'feedkeys'. We thank you for your suggestions. Hopefully you can also agree with our choice! Some suggestions were very nice, short and pretty unambiguous, such as Dennis' `emit` and particularly Alan's `strike`. However, they're unfortunately also rather rarely used and we'd be afraid that it'd be hard to remember them. Thank you though! A final point that Evan made and that also we find very important is to have verbs in our function names. Our proposed solution is to split what we previously called `type` into two functions, 'press' and 'enter' (proposed by xDog Walker). 'press' could be used to press single keys or combinations of them, at once: press(CTRL + 'a') press(ENTER) To open a menu via the keyboard, you could also supply several key combinations to be pressed, in sequence: press(ALT + 'f', 's') 'enter' on the other hand would be used to enter longer strings of plain text: enter(Hello World!) With a functionality we already have, you could supply an optional 'into' parameter that selects a text field into which the text is entered: enter(test.txt, into=File name) 'enter' currently does involve generating same system events that are fired when pressing (and releasing) sequences of keys. However, we did not want to include this technical detail in the function name - it keeps

However, you also understand me when I say enter. on the other hand, it lets you press single keys, That would be called typing. Here, I disagree. You press enter and you press ALT+TAB. You might be able to say type ENTER but that is much less common. Google agrees: http://bit.ly/10o8yAQ vs. http://bit.ly/WmVwyU. possibly in combination with control keys as for instance in `type(CTRL + 'a')`. That would be called prestidigitation. Nah, just kidding. That would also be called typing. Here too Google favours press ctrl+a over type ctrl+a. We believe it won't normally be necessary to combine the two. I can't imagine why you say that. You even go ahead and give a perfectly fine example of combining a control character with plain text. I don't know what operating system you are using, but under Linux, people often use strings of regular characters mixed in with control- or alt- characters. E.g. I in the shell, I might type Alt-B Shift-' END Shift-' to jump backwards one word (Alt-B), insert a double quote mark (Shift-'), jump to the end of the line I am editing (END), and insert another double quote mark. Unfortunately, I didn't explain what I mean by plain text. Your example could be implemented with the press from our proposal, as follows: press(ALT + 'B', '', END, '') What I meant when I said that press could not be used to enter plain text was that it would not be possible to enter a sequence of multiple normal letters enclosed in single quotes, as in press(Hello World) If in your example you had wanted to add more than just a single character to the beginning or end of the line, this means you would have to write press(ALT + 'B') enter(beginning of line) press(END) enter(end of line) I agree that the following would read better here: press(ALT + 'B') type(beginning of line) press(END) type(end of line) However like Google above, I would disagree with type(ALT + 'B') type(beginning of line) type(END) type(end of line) or even type(ALT + 'B' + beginning of line + END + end of line) It is a needless restriction to assume that every control character must only be part of a single key press event. I even remember a Mac application back in the early 1990s or late 1980s that used combinations like Ctrl-A Y to perform commands. (Actually, such older Macs didn't have a Control key, they used Command instead, but the principle is the same.) One of the main goals of our automation product is that using it should feel like giving instructions to a human being looking over their shoulder at a screen. In a word processor, I might say Type Ctrl-A Ctrl-X to cut all the text from the document. rather than Press Ctrl-A. Now press Ctrl-X. With the current proposal, it'd be press(CTRL + 'A', CTRL + 'X') Forgetting about `type` vs `press` for a moment, chaining the key combinations like this is OK, isn't it?

ANN : occmodel v0.1.0
I am pleased to announce the first official release of occmodel (v0.1.0) and the releated libraries geotools/gltools. Description -- occmodel is a small library which gives a high level access to the OpenCASCADE modelling kernel. For most users a direct use of the OpenCASCADE modelling kernel can be quite a hurdle as it is a huge library. The geometry can be visualized with the included viewer. This viewer is utilizing modern OpenGL methods like GLSL shaders and vertex buffers to ensure visual quality and maximum speed. To use the viewer OpenGL version 2.1 is needed. Home page : http://github.com/tenko/occmodel Documentation : http://tenko.github.com/occmodel/index.html In addition the following related libraries are released: geotools (required) : http://github.com/tenko/geotools Documentation : http://tenko.github.com/geotools/index.html gltools (optional) : http://github.com/tenko/gltools Documentation : http://tenko.github.com/gltools/index.html As this is the first official release some hurdles are expected Binary installers are available for the Windows platform.

Dear all,
the emails are getting kind of long so to ask you briefly: What do you
think of splitting `type` into two functions `press` and `enter`?
This invites confusion as to the rules of when you can call `press` and
when you can call `enter`. Especially since you haven't explained the
rules, just given a bunch of non-exhaustive examples and invited people
to extrapolate what the rules are.
(By the way, they aren't use-cases, they're examples.)
Their use cases are:
press(CTRL + 'a')
press(ENTER)
press(ALT + 'f', 's')
enter(Hello World!)
enter(test.txt, into=File name)
Is `press('s')` allowed?
What about `press('S')`, or do I have to write `press(SHIFT + 's')`?
If I can write `press(ALT + 'f', 's')`, can I write `press('f', 's')`? If
not, why not?
Can I write `press('fs')` as a simpler version of `press('f', 's')`? If
not, why not?
Can I write `press(CTRL + 'i')` to get a tab? How about `press('\t')`?
If I want three tabs, can I write `press('\t\t\t')`, or do I have to write
press(CTRL + 'i')
press(CTRL + 'i')
press(CTRL + 'i')
If I want a tab, a letter, and a newline, repeated three times, can I do
this?
press(\tA
\tB
\tC
)
Or do I have to do this?
press(CTRL + 'i')
enter('A')
press(CTRL + 'i')
enter('B')
press(CTRL + 'i')
enter('C')
Speaking of enter, how do I type Hello World! without entering it? If I
want to type Hello World! without ENTER, do I have to do this?
press('H')
press('e')
press('l')
press('l')
... you get the picture
With a function named press, I would expect to be able to say:
press('a')
time.sleep(5)
release('a')
How do I do something like that?

I don't think you could even do the former. An argument must be
optional in order to be mutually exclusive with anything. This works,
however:
parser = argparse.ArgumentParser()
group = parser.add_mutually_exclusive_group(required=True)
group.add_argument('--config', type=file)
group.add_argument('--foobar', nargs=2, metavar=('FOO', 'BAR'))
print parser.parse_args()
Downsides are that the resulting interface is a little more formal and
a little less friendly, and unless you customize the action you'll
wind up with a 2-element 'foobar' arg instead of separate 'foo' and
'bar' args.

The json module already has too many options. No need for yet one such
specialized.
class number_str(float):

... def __repr__(self):
... return str(self.o)
...
def decimal_serializer(o):
... if isinstance(o, decimal.Decimal):
... return number_str(o)
... raise TypeError(repr(o) + is not JSON serializable)
...
print(json.dumps([decimal.Decimal('0.20001')],
default=decimal_serializer))

You can extend this to support complex numbers, fractions, date and time, and
many other custom types. Have specialized options for this would be cumbersome.

[issue13475] Add '-p'/'--path0' command line option to override sys.path[0] initialisation
Kristján Valur Jónsson added the comment: Butting in here: Early on in the startup, a search is made for site.py using automatic sys.path settings. Do the suggestions here propose to override this? I know there is a -s flag, but all these flags start to be confusing. I have been looking for ways to completely ignore automatic settings for sys.path, either from internal heuristics (either build environment or installed environment) or PYTHONPATH. The reason for this is that as a developer in a large project, one that has many branches, each with their potentially different version of python compiled and with their own libraries, and where a standard python distribution may even be installed on the machine as well, we still want to be able to run scripts with each branch' own python with relative simplicity with some sort of guarantee that we are not inadvertently pulling in modules from other, unrelated branches, or god forbid, the installed python. PEP 405 seemed to go a long way, although it didn't provide a means in the pyvenv.cfg to completely override sys.path from the startup. I wonder if there isn't a synergy here with PEP 405, e.g. would it make sense to have a pyvenv.cfg file next to the __main__.py file? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13475 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Almost all the uses I can find are for simple functions/methods where all arguments are positional-only. (Ex: range, pow, slice, dict.pop). max and min *do* clearly need an error message fix.
