[Tutor] Problems understanding List reverse()

[Josh Gregorio]

I'm a newbie too, so this may not be the right way to do it. I found a
similar example on page 41 of Learning Python. The second to last paragraph
explains string.split (I have the first edition).

# a simple reverse function
import string #import the string module, chapter 3 in learning python
def reversel(list):
    list.reverse()
    return list

alist = []
alist2 = [1, 2, 3, 4, 5]
x = (raw_input('Enter a string:  '))
alist = string.split(x) #take the string and split its stuff into a list
print alist
print reversel(alist)
a = reversel(alist2)
print a

It only works if you enter a string with more than one word, like 'hello my
friend' or something. I'm not sure how to take a one word string like
'hello' and break it up into its individual characters. The following works,
but may not be the best/correct way to do it.

import string
x = 'hello'
alist = []
for i in x:
   alist.append(i)

print x
print alist
alist.reverse()
print alist


Thanks for any comments,

Josh
