The program don't complain wrong indentation, I mostly sure a wrong

My mistake, I thought that was improving the loop.
is it an if....elif....elif probing only the first matching case and drop the

Append() is a conventional name regarding a file logging.
There would be an option to set a quota of bytes size.

it isn't so, the function look at the string to see if ending by K or M,
which means Kbytes or Mbytes. It'll return the decimal conversion.
If the value is set as boolean value, then it will do appending to the log
when it True or stop appending when there's a quota.
def _append(c, v):
# any number of digit followed by 0 or 1 (k or m), case insensitive
k= 1024; M= k * k; v= int(value[:-1])
if value[-1:] == 'k': v= v * k
if value[-1:] == 'm': v= v * m
All the code could be download at my web site ;)
But this here it's a bit new concept.
