Since you are on this topic, do you (or anyone else) have any type of
code-completion mode for python in emacs?
Thanks

For what its worth, Vim has a generic type of code-completion that uses
the file being edited to check for completion options within a word. It's
not true

Yes, I must agree with you that it is something I should know. I do try
to keep with things but there are always some things that slip through the
cracks, like enumerate, in this case. That is why I am extremely grateful
the for the activity, generosity and pure knowledge on this
Wow, I didn't know about enumerate.
Many thanks

1. get arbitrary numerical data (typically large data sets in columnar
format or even via COM from other packages. I generally have to deal with
one or more sets of X,Y data)
2. manipulate the data (scaling, least squares fitting, means, peaks,
add/subtract one XY set from another etc)
You really owe it to yourself to try the PyParsing package, if you have to
do this kind of thing with any frequency.
The syntactic difference between PyParsing and regular expressions is
greater than the syntactic difference between Python and C.

Hi Doug
Not only was Kylix a letdown, there is talk also of it being
discontinued. To be fair though, it is easy to see the difficulty for
Borland to deploy a Linux IDE of the same quality as Delphi when so much
in different Linux distributions is variable, the widget set being a prime
In fact, as one of the Peter's (either Otten or Hansen) explained to me,
for line in open(file):
is actually both faster (being buffered) and generally better for very
large files because it doesn't read the whole file into memory, like
readlines does (if you have a memory limitation).

Speed is a contentious issue here. Point is, if you really need raw

The relative difference in speed between Perl and Python, whatever it is,

Assuming you have a file called data.txt:

You can make a huge investment by setting 2 or 3 hours aside to go through

Here is something I would try but don't have the guts for:
If you could write an extension to idle (yes, idle, not Boa, not Eric,
etc) that pops up a small list of possible completions in a listbox when
you type a '.' (period) after any object name or module name (including
builtins), that
and with
popen it comes with an error.
I haven't been able to read the stdin either so the problem so far is
unsolved for my point.
But the newline command would explain my problems with the program.

Steve,
I don't think I understand. Here is what I just tried:

In your example, x had not yet been initialised, maybe. What I am seeing
is that x does not

have everything, I guess :)

You get a (e.g.) variable name as a string, and you KNOW how to evaluate
