Need help with a string plz! (newbie)
Hi all
So I created a program, that gets a string from a user and then prints
the string in reverse order.
Now, here's the code;
#
print "\nWelcome !"
print "\nEnter a word, and the world will be reversed!"
word = raw_input("\nPlease Enter a word: ")
end = len(word)
end -= 1
for position in range(end, -1, -1):
print word[position],
raw_input("\nPress Enter to Exit")
What actually happens is, the next character is printed on the same
line but, there is a space inbetween each character.
I thought maybe I could create another variable and then assign each
character into the new string by concatenating, makign a new string
each time, but I find this a bit muddling at the moment. Any help'd be
great. Thanks.

Okay thanks very much, I used this method, since it's cloest one to I
am already faimilar with.
Here's the final code..(if anyones interested)
##
print "\nWelcome !"
print "\nEnter a word, and the world will be reversed!"
word = raw_input("\nPlease Enter a word: ")
end = len(word)
end -= 1
new_string = ""
for position in range(end, -1, -1):
new_string += word[position]
print new_string
raw_input("\nPress Enter to Exit")
