Two questions about complex numbers:
a) why are methods __add__,__mul__ defined but not the operators

How can I bind the methods to the obvious operators (without creating a custom

Why does the complex.__str__() method on complex numbers add the enclosing
parentheses?
It's unwanted, and it also makes them look like a tuple (other than the
trailing comma).
How can I get rid of it, other than the clunky:

Also Agile Testing.
(If they compare Agile in general to the other methodologies, that would be

Kent,
I was asking if it's a recognized good programming practice to
declare and initialize *all* members in the class defn.
What do you mean by "initialize *all* members in the class defn"?
- obviously I meant to say do it in the __init__() method,

Eric, you misunderstood my point.
I said you make a **token** assignment in the class defn simply
to do two things:
- 1) identify all the members in one place
- 2) annotate each member's type, as much as you can
e.g.:
class C
s = []
d = {}
ot = (None, None)
I didn't say you make the actual assign

Jim & Jaggo -
Dict lookup is (essentially) constant-time because the hashing function
computes which unique bucket a given entry will correspond to.
(Hashing functions are usually polynomials involving prime numbers.
Can assume that the computation of the hash value is constant-time)
So there is

Sorting both lists is unnecessary and not very scalable (order(NlogN)).
Assuming the lists do not contain duplicates,
just turn the longer one into a dict and check that each element of the
shorter list in that dict (e.g. "if j not in BigList: return false")
Since dict lookup is constant-time O(
in the question as stands.)

My friend said the runtime efficiency of Doxygen on his build was much
worse on the Python code than the C++ code, i.e. it took ages to parse
the Python code.
Anyone agree/disagree, or have any efficiency tips on how to structure
things for decent Doxygen performance?
(I haven't used Doxygen myse
I didn't suggest embedding C-specific stuff in the documentation;
I merely said the current tutorial is deficient on this topic; this is more
so important since the language is currently a moving target (as the

Hi Alan,
I don't deny the superiority of the underlying language design,
I'm just pointing out the very real mindjolting effect of Python not
supporting the universal syntax. Java is closer to C than Python is.
I'm bringing this up as one hurdle to migration, not a fundamental flaw.

Hi all,
As the Python doc says: "The for statement in Python differs a bit from what
you may be used to in C or Pascal. Rather than giving the user the ability
to define both the iteration step and halting condition (as C), Python's for

The doucmentation is confusing on that point.
Also when it refers to the methods becoming methods
of string objects a link would be nice.

Hi,
Where is there a table of replacements for the deprecated 'string' fns
esp. the basic common ones e.g. string.split(), join(), replace(), find(),
index() ?
http://docs.python.org/lib/node42.html
Are we supposed to use 're' fns even for very simple operations?
that seems like way overkill.
