Keeping focus with sequential Tkinter windows?
So, basically what I'm doing is this: window1 = Tkinter.Tk() ... window1.destroy() ... window2 = Tkinter.Tk() This works well in Linux and Mac OS X (and the PyGtk equivalent works on all platforms), but in Windows XP, the second window comes up without focus. (I have to click on it to focus it.) This is true even with no other windows on screen. I've tried window2.focus_set(), window2.lift(), etc., to no avail.

I think a more Pythonic way to write this, in general, would be:
while (1) {
char *tmp = fgets(buf, sizeof(buf), f);
if (!tmp)
break;
printf(%s\n, buf);
}
In actual Python, that's:
while True:
buf = f.readline()
if not buf:
break
print buf
Yeah, it's longer than the traditional C way, but you don't need to have
duplicate fgets() (or whatever) lines. On the plus side, you're less
likely to get '=' and '==' accidentally swapped in Python.
For this specific example, it can be cut down much more:
for buf in f.readlines():
print buf
(BTW, all of the above result in doublespacing the original file, but
that's what your C version was doing, so I kept it that way.)

When file-like objects aren't file-like enough for Windows
This is proving to be a recurring problem for me. First, I used the save() method of a Python Imaging Library Image object to write directly to the wfile of a BaseHTTPRequestHandler- derived class: pic.save(self.wfile, 'JPEG') Worked great in Linux, barfed in Windows. I had to do this to get around it: out = StringIO() pic.save(out, 'JPEG') encoded = out.getvalue() self.wfile.write(encoded) Now, I have a similar problem with subprocess.Popen... The code that works in Linux looks like this: source = urllib.urlopen(url) child = subprocess.Popen(cmd, stdout=subprocess.PIPE, stdin=source) try: shutil.copyfileobj(child.stdout, self.wfile) except: kill(child.pid) But wfile isn't the problem this time; instead, it's the source: ... child = subprocess.Popen(cmd, stdout=subprocess.PIPE, stdin=source) File C:\Python25\lib\subprocess.py, line 586, in __init__ errread, errwrite) = self._get_handles(stdin, stdout, stderr) File C:\Python25\lib\subprocess.py, line 698, in _get_handles p2cread = msvcrt.get_osfhandle(stdin.fileno()) IOError: [Errno 9] Bad file descriptor How can I get around this, short of resorting to copying all of the input before passing it to the child? -- 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 -- pass it on -- http://mail.python.org/mailman/listinfo/python-list

Removal of element from list while traversing causes the next element to be skipped
Look at this -- from Python 2.5.1:
a = [1, 2, 3, 4, 5]
for x in a:
... if x == 3:
... a.remove(x)
... print x
...
1
2
3
5
a
[1, 2, 4, 5]
Sure, the resulting list is correct. But 4 is never printed during the
loop!
What I was really trying to do was this:
apps = [name for name in os.listdir(ROOT) if
os.path.isdir(os.path.join(ROOT, name))]
apptitles = {}
for name in apps:
try:
app = __import__(name)
except:
apps.remove(name)
else:
apptitles[name] = getattr(app, 'TITLE', name.title())
which worked fine, until I actually had a directory with no module in it.
Then that directory was correctly removed from the list, but the _next_
one was skipped, so its title was never assigned, which caused problems
later in the program.

Big-endian binary data to/from Python ints?
Here are a couple of functions that I feel stupid for having written. They work, and they're pretty straightforward; it's just that I feel like I must be missing an easier way to do this... def net_to_int(numstring): Convert a big-endian binary number, in the form of a string of arbitrary length, to a native int. num = 0 for i in numstring: num *= 256 num += ord(i) return num def int_to_net(num): Convert a native int to a four-byte big-endian number, in the form of a string. numstring = '' for i in xrange(4): numstring = chr(num % 256) + numstring num /= 256 return numstring The situation: I'm getting a four-byte packet from a socket that consists of a big-endian 32-bit integer. (It specifies the length of the data that follows.) I have to send the same thing in reply. send() and recv() work with strings... I'm familiar with ntohl() and htonl(), but those expect/ return integers. -- 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 -- pass it on -- http://mail.python.org/mailman/listinfo/python-list
Performance on local constants?
Hi all,
I'm pretty new to Python (a little over a month). I was wondering -- is
something like this:
s = re.compile('whatever')
def t(whatnot):
return s.search(whatnot)
for i in xrange(1000):
print t(something[i])
significantly faster than something like this:
def t(whatnot):
s = re.compile('whatever')
return s.search(whatnot)
for i in xrange(1000):
result = t(something[i])
? Or is Python clever enough to see that the value of s will be the same
on every call, and thus only compile it once?
