Newb ?

[Chad Everett]

Hello all,

Have a problem here with a challenge from a book I am reading.
Any help is much appreciated.

I am trying to run a program that asks the user for a statement and then
prints it out backwards.
this is what I have.
It does not print anything out. I assume that I have something out of whack
with my high and low statements.

Thanks for you help.


print "\n\nWelcom e to the Backwards Message Display."
print
message = raw_input("\nPl ease Enter a Message.")

high = len(message)
low = -len(message)
print
print message[high:low]
print
print raw_input("Plea se Press Enter to Exit")

Are you sure that this is not a class assignment? You can search the
messages here for the answer.

No, I have been out of school way too long. I am 34 trying to learn a new
trade. I searched the group for the term backwards but I did not get any
results.

You might have better results searching for 'reverse'.

The problem is that negative numbers mean "count from the rightmost end
of the string or list." Also, you are going high to low without any
indication that you mean to go backwards.

Since you said it wasn't a school assignment, and I'm a trusting soul,
the next line could be:

print message[::-1]

Re: Newb ?

Hey guys,

Thanks for the hint.
I found that info last night but I could never get it to print more than
just the last letter.
or it would only print partially.
I was using just a single colon, the double colon did it.

Thanks

If you were using a single colon, then it would print everything except
the last character. Use the Python interactive mode for experimentation .
