all i want to do is count the lines in each file

[Skaperen]

all i want to do is count the lines in each file but there are strange binary bytes or older ISO codes.

Output:
Traceback (most recent call last):
  File "last-edited.py", line 38, in <module>
    pf(t,n)

    c = len([x for x in f])

            nt[n].append(t)
        else:
            nt[n] = [t]

    t = nt[n][-1]
    if t[13]=='-':
        t=t[0:7]+t[8:13]+t[14:16]+t[17:]
    tn[t] = n
for t,n in sorted([x for x in sorted(tn.items())]):
    if argv:
        for a in argv:
            if n.endswith(a):
                if os.path.exists(n):
                    pf(t,n)
                break
    else: # none requested so print all
        if os.path.exists(n):
            pf(t,n)

i think the only things it uses from sfc are os and cd (called with no args changes directory to user home directory.
