hi all,
the code works:
####
s='00101'
found = False
for i,c in enumerate(s):
if c == '0':
print 'Lane fail',i
found = True
if not found: print 'All lanes PASS
No, it doesn't work. You haven't sufficiently tested it. It tells lies:
>>> s='11100101'
>>> found = False
>>> for i,c in enumerate(s):
... if c == '0':
... print 'Lane fail',i
... found = True
... if not found: print 'All lanes PASS'
...
All lanes PASS
All lanes PASS
All lanes PASS
Lane fail 3
Lane fail 4
Lane fail 6
All lanes did NOT pass.
the enumerate is checking from left to right. is it possible check from right to left?
for eg:s='00101'
Will give below result:
Lane fail 1
Lane fail 3
Lane fail 4
for i,c in enumerate(reversed(s)) is the easiest way.
