Hello, I am looking for some advice as to the best way to generate a file path using variables, currently my code looks similar to the following: path = /my/root/directory for x in list_of_vars: if os.path.isdir(path + '/' + x): # line A print(x + ' exists.') else: os.mkdir(path + '/' + x) ...
Is there a similar mechanism in Python, to the effect set -x has on bash? Here's some example output from bash in this mode: + for src in cpfs.c log.c popcnt.c ssse3_popcount.c blkcache.c context.c types.c device.c ++ my_mktemp blkcache.c.o +++ mktemp -t blkcache.c.o.2160.XXX ++ p=/tmp/blkcache.c.o.2160.IKA ++ test 0 -eq 0 ++ echo /tm...
When printing a formatted string with a fixed length (e.g, %20s), the width differs from UTF-8 string to a normal string: >>> str1="Adam Matan" >>> str2="אדם מתן" >>> print "X %20s X" % str1 X Adam Matan X >>> print "X %20s X" % str2 X אדם מתן X Note the difference: X Adam Matan X X אדם מתן X Any i...

I have a connection which is behind a restrictive firewall which only allows HTTP(S) access through a proxy (10.10.1.100:9401). The IP address I get is dynamic and the subnet mask is 255.255.255.255 (I know, weird!). I tried to write a simple Python socket program to connect to the proxy in order to send some HTTP requests: import sock...
I am basically looking for the Python equivalent to this VB/VBA string operation: FullName = LastName & ", " + FirstName In VB/VBA + and & are both concatenation operators, but they differ in how they handle a Null value: "Some string" + Null ==> Null "Some string" & Null ==> "Some string" This hidden feature allows for the first l...

I have already taken a look at this question: SO question and seem to have implemented a very similar technique for replacing a single color including the alpha values: c = Image.open(f) c = c.convert("RGBA") w, h = c.size cnt = 0 for px in c.getdata(): c.putpixel((int(cnt % w), int(cnt / w)), (255, 0, 0, px[3])) ...

I have a peculiar SQLAlchemy ORM problem. This is occurring in a Pylons application, against a Postgresql 8.2 database using psycopg2 as my database driver under SQLAlchemy 0.6.0 (and tried with 0.6.4 as well) I have defined a User model object that has (at minimum) the following properties: class User(Base): __tablename__ = 'users...

Hello, I am getting unexpected(?) results from this mergesort implementation. It's extremely slow compared to my three-way quicksort(also written in python). My quicksort finishes with 10000 elements after about 0.005s while mergesort needs 1.6s! Including the source code for both implementations. Mergesort: #Merges two sorted lists...
I am working on a Pylons app that runs on top of Apache with mod_wsgi. I would like to send logging messages that my app generates to files in my app's directory, instead of to Apache's logs. Further, I would like to specify the location of logfiles via a relative path so that it'll be easier to deploy my app on other people's servers....
