No newline using printf

[Samuel]

Hello,

I have been searching for an answer for almost two hours now and have
not found an answer. I want this code:

for i in range(3):
print i # or whatever

To produce this output:
012

How can I print a word without appending a newline character? Appending
a "," to the print statement only substitutes the newline for a space,
which is not what I am looking for.

Any hints?

Thanks,
-Samuel

Use sys.stdout.writ e directly.

For closer control over output, use the write() function. You want
something like:

import sys
for i in range(3):
sys.stdout.writ e (str(i))

Try with:

print ''.join(str(foo ) for foo in range(3))


or sys.stdout.writ e

here is the output of my machine:
[color=blue][color=green][color=darkred]
>>> import sys
>>> for i in range(3):[/color][/color][/color]
... sys.stdout.writ e(str(i))
...
012>>>

Why the prompt followed after the output? Maybe it's not as expected.

Because, unlike print, sys.stdout.writ e() just sends the raw bytes
directly to the output without special formatting, extra characters
(such as the newline print adds for you), or other interference.

Add the newline yourself after the loop to fix this:

sys.stdout.writ e('\n')

Because it did what you ask of it: write "012" to stdout, and nothing
else. Hence, no newline at the end, hence the prompt is on the same
line.

The solution is to take over full control of the output with
sys.stdout.writ e.

Use '%1d' % i to convert your number into a single character string.

Use sys.stdout.writ e to send exactly the characters you want to sys.stdout.

Thus: sys.stdout.writ e('%1d' % i) should do what you want.
