To my horror, someone pointed out to me yesterday that a web app I
wrote has been prominently displaying a misspelled word. The word was
buried in my code.
Is there a utility out there that will help spell-check literal
strings entered into Python source code? I don't mean spell-check
strings en

Perhaps it is not as severe a security risk, but pure Python programs
can run into similar problems if they don't check user input for %
codes. Example:
>>> k = raw_input("Try to trick me: ")
Try to trick me: How about %s this?
>>> j = "User %s just entered: " + k
>>> print j % "John"

Yup, join is better. The problem with using form.values() is that it
will break if the HTML changes and adds some sort of new field that this
function does not care about, or if an attacker introduces bogus fields
into his query.

Try this:
if form.get("delete_id","") != "" and form.get("delete_data","") != ""
and...
the "get" method lets you have an optional second argument that gets
returned if the key is not in the dictionary.
Also, am I reading your code right? If I enter some fields but not all,

Your list probably contains several references to the same object,
instead of several different objects. This happens often when you use a
technique like:
list = [ object ] * 100
..because although this does make copies when "object" is an integer, it
just makes references in other cases.

A quick fix: change your last two functions to:
def generateNotMatching(A,n,P):
for g in gen(A,n,P,[]):
for x in g:
yield x
def gen(A,n,P,acc):
if any(imap((lambda p: allStar(p) and notNullOrZero(p,n)), P)):
yield []
else:
if n==0:
Rather than a list comprehension, it would be faster and more
memory-efficient to use a generator comprehension. Just change the
square brackets to parentheses:
for j in (i*2 for i in c if ):
print j

On my slow notebook, your code takes about 1.5 seconds to do my

Here is my code:

Also, with the functional programming tools of map, filter, and lambda,
this code can be reduced to just six lines:

If you have already read the string into memory and want a convenient
way to loop through it 3 characters at a time, check out the "batch" recipe:

It uses itertools to make an iterator over the string, returning 3

I know of no built-in way, but you could probably code this in a few
lines using print "%.1f" and so on.
(Some of us, by the way, are in the camp that believes a kilobyte is
1024 bytes, not 1000, so 103803 bytes for us is about 101.4 kilobytes).

Don't overly concern yourself with your course being 100% up to date.
When learning programming, the concepts are what is important, not the
syntax or libraries you happen to be using. Even if they were to teach
you the latest and greatest features of 2.4.2, that would be out of date
in a few
It works fine for me. You must be having an indentation problem.
Also, get rid of the comma at the end of that last print statement.

This should be just a matter of determining how your string is encoded
(ASCII, UTF, Unicode, etc.) and checking the ord of each character to
see if it is in the contiguous range of English characters for that
encoding. For example, if you know that the string is ASCII or UTF-8,
you could check

Wouldn't this print two line breaks--the one you specify in the string,
plus the one always added by print if there is no comma at the end of
the statement?

As mentioned in the thread, it makes sense to build the desired output
you want from the tuple, rather than converting the tuple to a string
and then doing replace operations on the string.
If you do want to go the replace route, you don't need the power of
regex substitutions for what you are
import os, os.path
path_to_nethack_logfile = ""
for root, dirs, files in os.walk("c:\\"):
if 'nethackdir' in root:
logs = [x for x in files if 'logfile' in x]
if len(logs) > 0:
path_to_nethack_logfile = os.path.join(root, logs[0])
exit

Assuming you are running on an operating system that uses file

something like this will work:
