yay!!

again there were typos in the wiki:

Code:

dir_name = "src"

for root, dirs, files in os.walk(dir_name):
        real_dir = root[len(dir_name):]

For who left only "src", the code should look like:

Code:

dir_name = "src"
for root, dirs, files in os.walk(dir_name):
        real_dir = root

what was going on? simply string stripping: root[len(dir_name):] means that you're doing root[3:]. you want to strip the string from the 3rd position to the end: example:

Code:

 a="src"
In [13]: len(a)
Out[13]: 3
In [14]: cacca=[1,2,3,4,5,6,7]
In [15]: cacca[len(a):]
Out[15]: [4, 5, 6, 7]
In [16]: cacca[:len(a)]
Out[16]: [1, 2, 3]

.

final remarks: this is what was meant to be:

Code:

for root, dirs, files in os.walk(dir_name):
        real_dir ="//" + root[len(dir_name):]

the double slashes are also required to fix the pathname.
so I will edit again the wiki. solving this other one.
hope I've help someone in saving time.
