I have studied generators feature and i think i got it but i would like to understand where i could apply it in my code.
I have in mind the following example i read in "Python essential reference" book:
# tail -f
def tail(f):
f.seek(0,2)
while True:
line = f.readline()
if not line:
time.sleep(0.1)
continue
yield line
Do you have any other effective example where generators are the best tool for the job like tail -f?
How often do you use generators feature and in which kind of functionality\part of program do you usually apply it?
