List conversion

[yawgmoth7]

Hello, I have a piece of code:

command = raw_input("comm and> ")
words = string.split(co mmand, ' ')
temparg = words
if len(words)<= 3:
temparg = words[4:]
else:
temparg = words[5:]
funcarg = string.upper(te mparg)
str(funcarg)
continue

There's a little snippet of code from my script, it all looks fine,
well, then I have a function that looks something like:

def nick(funcarg):
sock.send(funca rg\r\n)
Well, that's okay, but i get this error when I try to run that command
at the commmand prompt like enviroment I wrote:

TypeError: send() argument 1 must be string or read-only buffer, not list

Well, that is why I put in the str(funcarg) line, hoping that it would
convert it to a string, instead of being a list, does anyone have any
suggestions, thanks, bye.

Well, I'm sorry to have to say this, but it doesn't look fine at all:
[color=blue][color=green][color=darkred]
>>> words = "one two three".split()
>>> words[/color][/color][/color]
['one', 'two', 'three'][color=blue][color=green][color=darkred]
>>> len(words)[/color][/color][/color]
3[color=blue][color=green][color=darkred]
>>> words[4:][/color][/color][/color]
[][color=blue][color=green][color=darkred]
>>> import string
>>> string.upper(wo rds[4:])[/color][/color][/color]
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib64/python2.4/string.py", line 235, in upper
return s.upper()
AttributeError: 'list' object has no attribute 'upper'[color=blue][color=green][color=darkred]
>>> str(words[4:])[/color][/color][/color]
'[]'[color=blue][color=green][color=darkred]
>>> words[4:][/color][/color][/color]
[][color=blue][color=green][color=darkred]
>>>[/color][/color][/color]

Python comes with an interactive interpreter that makes testing and
exploring a breeze. Why not using it to see how things works and avoid
obvious errors ?-)

Either it's not your real code or you should have another error:
[color=blue][color=green][color=darkred]
>>> def send(aString):[/color][/color][/color]
.... print "sending %s" % aString
....[color=blue][color=green][color=darkred]
>>> send(words[4:]\r\n)[/color][/color][/color]
File "<stdin>", line 1
send(words[4:]\r\n)
^
SyntaxError: invalid token[color=blue][color=green][color=darkred]

This is called "programmin g by accident", and it's the worst thing to
do. Don't "hope", try and make sure:
[color=blue][color=green][color=darkred]
>>> str(words)[/color][/color][/color]
"['one', 'two', 'three']"[color=blue][color=green][color=darkred]
>>> words[/color][/color][/color]
['one', 'two', 'three'][color=blue][color=green][color=darkred]
>>>[/color][/color][/color]

As you can see, str() :
- returns a *representation * of it's arg as a string - but this
representation may not be what your looking for
- does *not* modify it's argument.

What you want here is to join the parts of the list:
[color=blue][color=green][color=darkred]
>>> " ".join(word s)[/color][/color][/color]
'one two three'

Yes :
1/ there are at least two good tutorials, the one in the official
documentation and Dive Into Python (diveintopython .org IIRC).

2/ don't guess, don't hope, *test* (hint : use the interactive interpreter).

3/ (optional) don't hold it against me if all this sounds a bit harsh.

thanks, bye.[color=blue]

needs a whitespace after the two dashes. It's '-- ', not '--'.
