Thanks a lot for various notes. Bonono? I will have to look at the itertools module. Just went to the doc http://www.python.org/doc/2.4.1/lib/module-itertools.html looks interesting. > But I believe Python is designed for easy to code and read and maintain > in mind. > One has to admit that with

Re: write a loopin one line; process file paths

it will be added in 2.5 I beleve. At the moment, you can: predicate and or like : >>> os.paths.exists(something) and "print it is there" or "file not found" I am practicing FP in python and it is in general doable with the help of itertools and add the needed functions as needed, like scanl/sc

Re: write a loopin one line; process file paths

Thanks. Here's how the inner loop should be: imgPaths2=map(lambda x: (x, re.sub( r"^(.+?)-s(\.[^.]+)$",r"\1\2", x)), imgPaths) though, now i just need something like map( lambda x: os.path.exists(s)? x[1]:x[0],impPaths2) but Pyhton doesn't support the test ? trueResult : falseResult construct.

Re: write a loopin one line; process file paths

what do you mean by one line ? Using map/filter, I believe it is possible. Somthing like: map(lambda (s,f): os.path.exists(f) and f or s, map(lambda x: (x, re.replace(x, "-s","")), imgPaths) My regex is a bit rusty but I hope you got the idea of what I am trying to do. If there is a way to m
