Thanks for the information about unicode.
Actually, I am using python 2.7 in Windows XP.
IDE: PyScripter.
So, I run the same code in IDLE (Python 2.7).. Its working. It isn't
showing the list in unicode format!
Nothing to do with list. Reread my remarks. The string is apparently
unicode, presumably from the raw_input() call. The IDE must be changing
the type of stdin to make it unicode.
Did you try print repr(name1) ? I'll bet that's also a unicode
string.
And you tried it in another IDE, IDLE. But the key question is how it
behaves in raw Windows, from a command prompt. The user of your code is
unlikely to set up your particular IDE to run something you've written.
As for an IDE, the only free one I use is emacs. I've heard good things
about pywin (or something like that), a free IDE that comes with the free
ActiveState python. The Active State python also includes some extensions
specifically for Windows, and to make it easier to use Windows dll's and
com objects. I used to use the ActiveState stuff when I used Windows.
The following material is out of order, but I left it in anyway, for some
context.
I've used PyScripter many times before and worked on lists.. but I never
faced any problem like this

Hi,
Just take a look at this small code.. I am just taking a string as
input and assigning it as a list.
But I am finding an unexpected entry in the list.. Why this is
happening?
I am using PyScripter IDE.
code :
#!/usr/bin/env python
def main():
pass
if __name__ == '__main__':
main()
print "Flames: "
name1 = raw_input('enter name 1')
ListName1 = list(name1)
print name1
print ListName1
Output:
Flames:
foo
[u'f', u'o', u'o']
Observe the last line.. it isn't showing [ 'f', 'o', 'o']
Why is that "u" coming in the middle from no where ??
The u"" notation just says it's a unicode string. No more confusing
than the [] meaning it's a list. Neither is the content of the object,
just showing you textually what the type is. You should also print
repr(name1) to see if it is likewise a unicode string. I presume it's
already unicode when returned by raw_input().
My puzzle is how you got unicode strings, if you've shown your entire
program. In Python3, all strings are unicode, so it wouldn't bother to
say so. Besides, your code has a syntax error in it, if it's supposed
to be Python 3.x
You probably need to identify your particular version of Python, and
the platform (OS) you're running it on.
But it could be affected by your IDE (Pyscripter), or by a site.py or
other implicitly loaded module.
You can check for the former by running the script from a command shell.

Dave, I am now puzzled.. I
don't understand but the list is now not showing unicode. I just restarted
the IDE and rewrote the code again!
however, I tried print repr(name1), it didn't show me any unicode notation.
