Save output to new file every 10 seconds in Python 3 -


i have output flow com-port , want save files, @ every 10 second new file.

i can read com-port this:

import sys import datetime, threading   line in sys.stdin:     print(line)     my_writing_function(line)

i need change filename every 10 seconds, so, need this:

def filename():     # if opened -> close.     filename='{0:%y-%m-%d_%h:%m:%s}'.format(datetime.datetime.now())     fh = open(filename, "a+")        threading.timer(10, filename).start()

but in case fh should global.. may need make flag , check before writing?

thanks.
