Hello,

I have one simple string, backspace character question.Here is my
example:

text="Hello\bworld"
print text

"HelloBSworld"

Should this character "\b" (backspace) in this text return this:
"Helloworld"?

Regards,

Hi,

If you mean on operating system then unfortunately Windows XP.

Point (1) Works on Windows XP for me:

C:\junk>ver

Microsoft Windows XP [Version 5.1.2600]

C:\junk>\python25\python
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

text = "Hello\bworld"
print text
Hellworld

or, for mild amusement:

import sys, time
for x in xrange(100):

... sys.stdout.write("|/-\\"[x & 3] + "\b")
... time.sleep(0.1)
...

Now try it on IDLE.



Point (2): Backspace??? YAGNI --- backspace hasn't been much use for
anything (except when typing text) since the days when in order to get
a bold letter (say X) on a character impact printer, one would
transmit X\bX\bX ...
