Hi all
I have a question arising from another thread, but on a different topic,
hence the new thread.
Under Python2, if you want to print a series of dots to the screen without a
newline, you can do the following:
for i in range(10):
sys.stdout.write('.')
sys.stdout.flush()
time.sleep(1)
sys.stdout.write('\n')
I tried it under Python3, and found that it differs in two ways -
1. Each 'write' is terminated by a newline
2. Each 'write' appends the length of the string written.
So instead of -
..........
I get -
.1
.1
etc
I found that the new 'print' function has a 'flush' argument, so it can now
be written as -
for i in range(10):
print('.', end='', flush=False)
time.sleep(1)
print()
I tried to read the docs on sys.stdout, and I see a lot of changes in this
area, but I could not see the reason for the above behaviour.
Is there a way to reproduce the Python2 behaviour in Python3 using
sys.stdout?
Thanks
Frank Millman
