It's written into the article, maybe I should write it on the sheet too. -- GreyFox -- http://mail.python.org/mailman/listinfo/python-list

I listed it because of help(dict.has_key) doesn't show any warning about that. However, if "in" works as well, I'll remove it very soon. > Also, consider adding a line or two about the set objects.

That's a typo, thank you.

Yes, it's more clear now.

Whoops, I'm sorry :)

Since open() is just an alias for file(), changing the name should be
enough, right?

What do you think about adding a line like this to the examples?
for line in open("filename","r"): pass #iterate over lines
> Do you know about seq[i:] and seq[::-1]?
Yes I know. I'll try to add them (together with seq[:] and seq[:j]).
Thank you very much indeed :)

I see, it has already been signaled by mail. I'm not sure about how to fix that, I'll have to ask someone who knows Inkscape. Thanks. I'm working at the next release now, it should be available quite soon. -- GreyFox -- http://mail.python.org/mailman/listinfo/python-list

Yes I know, it has already been signaled by mail. They will be removed in the next version, except pow (the version with two arguments that is in my list belongs to math, while pow(b,e,m) is from __builtin__). > Note pow(base, exponent[, modulus] is good for crypto stuff. > Useful modules to read actually should include __builtin__, > os, and os.path -- maybe include os.walk and os.path.join. Maybe I'll add __builtin__ and os in place of the type hierarchy, but I'm not sure about that. However, not in the next release. What do you think about? -- GreyFox -- http://mail.python.org/mailman/listinfo/python-list

That's strange... however, since there are no doubts about open(), I'll use that :) -- GreyFox -- http://mail.python.org/mailman/listinfo/python-list
