Hello,
I have this problem. Write a program named litter.py that creates an empty file named trash.txt in each subdirectory of a directory tree given the root of the tree as an argument (or the current directory as a default). So I change the example to this : def traverse(path, s='.\n', f=0, d=0): path2file = os.path.join(path) *** pathfile contains the path if os.path.isdir(path2file): **** if pathfile is a dir. d += 1 ***** the is one more directory if getdirlist(path2file): ****** if the outcome of getdirlist is the same as the current directory s, f, d = traverse(path2file, '| ' + s, f, d) do this module again else: f += 1 ****** else f (number of files increases with 1 return s, f, d ****** return s , numbers of files and the number of directories. When I try to make it run I get this message : File "C:\Users\wobben\workspace\oefeningen\src\test.py", line 31, in traverse s, f, d = traverse(path2file, '| ' + s, f, d) File "C:\Users\wobben\workspace\oefeningen\src\test.py", line 31, in traverse s, f, d = traverse(path2file, '| ' + s, f, d) File "C:\Users\wobben\workspace\oefeningen\src\test.py", line 31, in traverse s, f, d = traverse(path2file, '| ' + s, f, d) File "C:\Users\wobben\workspace\oefeningen\src\test.py", line 28, in traverse if os.path.isdir(path2file): File "C:\Python27\lib\genericpath.py", line 44, in isdir return stat.S_ISDIR(st.st_mode) File "C:\Python27\lib\stat.py", line 41, in S_ISDIR return S_IFMT(mode) == S_IFDIR RuntimeError: maximum recursion depth exceeded I can't see why this happens. I know I have to fish but I can't see what's wrong here. So I hope someone can learn how to fish here.
