How may I create list of lists in Python to store list of texts? -

-

i trying open bunch of files directory , trying put results in list of lists say,

that say, have list of file names of directory, want read each 1 of them. after reading each 1 of them, want put results of each file in list. these lists again inserted create list of lists.

to trying write follows:

list_of_files = glob.glob('c:\python27\*.*')     print list_of_files     list1=[]     list2=[]     list_n=[list1,list2]     i,j in zip(list_of_files,list_n):         print i,j         x1=open(i,"r").read()         x2=j.append(x1)     all_sent=list_n     print all_sent

am doing wrong? if 1 may kindly suggest? there smarter way it? using python2.7 on windows 7 professional edition. have many list of lists question in python have reviewed them. posting did not match. apology cross posting. if may direct me previous post, surely delete post.

try using following list comprehension:

list_of_files = glob.glob('c:\python27\*.*') data = [open(file, 'r').read() file in list_of_files]

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
