Append() and raw_input()

Hi, I have not been doing python for that long so please bear with me. Here is an example of the problem I am having:

list = []
input = raw_input()
list.append(input)
print list

when I print "list" I get the individual letters I typed when assigning "input" like this:

['i, n, p, u, t']

why isn't is giving me the whole word?

thanks in advance

I've put your program into file p.py, and on the command line I execute, `hmmph' my input is shown

$ python p.py
hmmph
['hmmph']
$

I don't comprehend the problem. raw_input returns the keyboard input without the new line as a string.

1) Hiding the names of builtin functions is usually bad practice. You hid both `input' and `list'.

2) If still confused please show the input you provide and the output you expect. I think explaining what you think python does is counterproductive, because it's not yet correct.

Getting ['i, n, p, u, t'] doesn't make any sense, unless
you entered the string i, n, p, u, t

Avoid using Python function names as variable names.
When in doubt prefix with my like this:

Code:

mylist = []
myinput = raw_input()
mylist.append(myinput)
print mylist

This looks like the result of using extend() instead of append(). Is the code you wrote here copied verbatim from what you actually ran?

Sharp mind Nyktos!

Code:

mylist = []
myinput = raw_input()
mylist.extend(myinput)
print mylist

''' result typing in the word input -->
['i', 'n', 'p', 'u', 't']
'''

sorry, when I was messing around with something else I must have tried extend() and not changed it. I have changed it now and it works, thanks for the help!
