In the head of an HTTP response, most servers will specify a
Content-Length that is the number of bytes in the body of the response.
Normally, when using the GET method, the header is returned with the
body following. It is possible to make a HEAD request to the server
that will only return header
I just did some timings, and found that using a list instead of a
string for tok is significantly slower (it takes 1.5x longer). Using a
regex is slightly faster for long strings, and slightly slower for
short ones. So, regex wins in both berevity and speed!

Thank you for your corrections to the previous code. Your regex
solution is definitely much cleaner. Referring to your other
suggestions, is the advantage of using a list of chars instead of
adding to a string just a bow to big-O complexity, or are there other
considerations? First I had tried appe
I found that I was repeating the same couple of lines over and over in
a function and decided to split those lines into a nested function
after copying one too many minor changes all over. The only problem is
that my little helper function doesn't work! It claims that a variable
doesn't exist. If I

You could try SciTE. It has syntax highlighting for almost every
language I have heard of plus some, and seems to work pretty well. It
has some issues with fonts, and on some computers is unstable (it
crashes in linux, and may have issues with multiprocessor machines).
I would also like to know if
In the following program I am trying to learn how to use functional
programming aspects of python, but the following program will crash,
claiming that the recursion depth is too great. I am attempting to make
a list of polynomial functions such that poly[0](3) = 1, poly[1](3) =
3, poly[2](3) = 9, e
Hello. I am very new to Python, and have been unable to figure out how
to check if a variable exists or not. In the following code I have made
a kludge that works, but I think that it would be clearer to check if
closest exists and not have to initialize it in the first place. How is
that check don
