Question regarding Higher-Order-Programming in Python
I am about to learn Higher-Order-Programming with Lisp, Haskell, and
Python. Some people who have gone completely out of their mind call
this FP.
In Haskell I learned that when I use map on a list it starts nesting
as soon as I start adding elements. If I do not like the nesting I use
ConcatMap.
In Python I have a similar scenario. I have a generator which creates
some combinatorics of a input dictionary. The list starts nesting. Now
I could use reduce(concat, ...) which would be the correct thing from
a functional perspective. But from a resource utilization perspective
it is not a good idea since the reduce is executing the generator.
I tried to illustrate this using a small example (the often in
combinatorics the real thing would be much bigger that is why I need
to use a generator):
from operator import itemgetter, concat
import itertools as it
from functools import partial
dims = {'number': [1,2,3], 'letter': ['a', 'b'], 'special': ['+', '-']}
dims
{'special': ['+', '-'], 'number': [1, 2, 3], 'letter': ['a', 'b']}
def get_products(keys):
... # helper to get products from keys in the following form:
... # [('bold', True), ('color', 'black')]
... values = itemgetter(*keys)(dims)
... product = it.product(*values)
... return map(partial(zip, keys), product)
...
comb = it.combinations(dims, 2)
comb_l = list(comb)
comb_l
[('special', 'number'), ('special', 'letter'), ('number', 'letter')]
res = map(get_products, comb_l)
res
[[[('special', '+'), ('number', 1)], [('special', '+'), ('number',
2)], [('special', '+'), ('number', 3)], [('special', '-'), ('number',
1)], [('special', '-'), ('number', 2)], [('special', '-'), ('number',
3)]], [[('special', '+'), ('letter', 'a')], [('special', '+'),
('letter', 'b')], [('special', '-'), ('letter', 'a')], [('special',
'-'), ('letter', 'b')]], [[('number', 1), ('letter', 'a')],
[('number', 1), ('letter', 'b')], [('number', 2), ('letter', 'a')],
[('number', 2), ('letter', 'b')], [('number', 3), ('letter', 'a')],
[('number', 3), ('letter', 'b')]]] # the resulting list is nested one
level to deep caused by the map(get_products, ..
My problem is that I want to get single elements from the generator
like [('special', '+'), ('number', 1)]. But this does not work because
the list is now nested to deep.
That is what I expect: (I could get something like that with the
following res = reduce(concat, res)
[[('special', '+'), ('number', 1)], [('special', '+'), ('number', 2)],
[('special', '+'), ('number', 3)], [('special', '-'), ('number', 1)],
[('special', '-'), ('number', 2)], [('special', '-'), ('number', 3)],
[('special', '+'), ('letter', 'a')], [('special', '+'), ('letter',
'b')], [('special', '-'), ('letter', 'a')], [('special', '-'),
('letter', 'b')], [('number', 1), ('letter', 'a')], [('number', 1),
('letter', 'b')], [('number', 2), ('letter', 'a')], [('number', 2),
('letter', 'b')], [('number', 3), ('letter', 'a')], [('number', 3),
('letter', 'b')]]
I have seen the problem many times but so far I could not google a
solution on the web.
By the way do you know any substantial example using FP in Python
(generators, imap, ifilter, ...)?

so far I have never noticed chain.from_iterable, but many thanks to
you Peter, I have now a beautiful solution to this problem.
from itertools import chain
comb = it.combinations(dims, 2)
l = chain.from_iterable(it.imap(get_products, comb))
l.next()
[('special', '+'), ('number', 1)]
l.next()

Jython Pythonpath question
Hi there, I have a source file FailFixture.py in the folder D:\AUT_TEST\workspace\JyFIT\testutil. Now I want to import the file with import testutil.FailFixture.

Re: Jython inherit from Java class
Hi Kent, many thanks for your help! In the meantime I received my Jython Essentials book and hope that I have much fewer questions in the near future. One last question for this thread. I tried to inherit from a Java class and override on method. I figured that this approach was nonsense because the method used private attributes of the Java class. Now I read that there is injection used in Jython. Jython uses setter and getter methods to do the injection, right? Unfortunately the Java class has no setters and getters for the private members. Is there another way to override the method besides rewriting the Java class or is this approach really doomed? Cheers, Mark -- http://mail.python.org/mailman/listinfo/python-list
Re: Jython inherit from Java class
Please enlighten me. This seemed so easy yust inherit from a Java class overwrite one method - done. At the moment I do not know how to proceed :-(( Jython or jythonc? == In general is it better to run programms with the jython interpreter or is it better to compile them first? I had the impression that the inheritance does not work with the interpreter. Is that right? 2.1 or 2.2a === The programm did not compile with the 2.1 version and Java 1.5. But with 2.2a it compiled but 2.2a is an alpha version. Assuming the programm would compile with the Java 1.4 version would it be better (saver, more stable, performance) to use 2.1 or 2.2a? Inherit from java baseclass or reimplement the whole thing in jython? = All the problems with Jython stated when I wanted to inherit from a Java baseclass. I wounder if I would have more success when implementing it in pure Jython. Regarding the inheritance I had an empty wrapper arround the Java baseclass and 70% of the unit test passed. But the performance was ~ factor 10 slower than using the base class directly. Does this mean that there is overhead with the inheritanc construct and that this implementation path would always be so slow. On the other hand would a 100% Jython solution be faster?

Re: rexec in jython??
This is the original code section of the library including the comments: class AutoAdapter(TypeAdapter): This adapter returns a type based on the format of the table cell contents, following python's rules for literals (plus a few others). We could fall back on this when we don't know what type is expected. I am lazy and so use rexec to do the work. #Note: The RExec class can prevent code from performing unsafe #operations like reading or writing disk files, or using TCP/IP #sockets. However, it does not protect against code using #extremely large amounts of memory or processor time. r_eval = RExec().r_eval def parse(self,s): if s.strip().lower() == 'true': return 1 elif s.strip().lower() == 'false': return 0 else: try: return self.r_eval(s) except SystemExit: return None except: return s I completely removed the import of rexec and replaced return self.r_eval(s) with return self.eval(s) -- http://mail.python.org/mailman/listinfo/python-list
Re: rexec in jython??
:-))) it works! I replaced it to return eval(s) and the results look extremely well guess I should get one of this crystal balls myself. one minor issue is still left: correct me if I am wrong: result of 2/-3 is 0 (at least this is how it is defined in the testcase) In Jython 2.1.3: 2/-3 -1 Anyway many thanks for your help.

jython how to use Fit and Fitnesse
Hi there, I want to ask how to use Fit and Fitnesse together to use testcases programmed in Jython. Resently I discussed with John Roth how PyFit would have to be changed to work together with Jython. This seems to be a lot of work and comes maybee with version 0.9 in mid 2006 if at all. I think that it is possible to use Fitnesse and Java Fit and involve Jython testcases with this configuration but I do not know how.
