Need some help...

I want to create a program that I type in a word.

for example...

chaos

each letter equals a number....

A=1
B=20

and so on.

So Chaos would be

C=13 H=4 A=1 O=7 S=5

I want to then have those numbers
13+4+1+7+5 added together to be 30.

How can I do that?

Also, just curious, but, how could I then have the 3 and 0 added
together to be 3?

Please help me out.

Thank you.....

You can see that Python has a command to input strings from the
command line.

Python has a dictionary data structure called dict(), or {}, that you
can use to map your letters to those numbers. With it you can created
the letter-number association.

Then you can scan the characters of the input string one after the
other, and sum their values into a single total value. Try writing
that code, and then show it to us, we can give more suggestions if you
need them...

If the values are arbitrary:

letters_values = {'A':1, 'B':20, 'C':13, 'H':4, 'O':7, 'S':5, #etc...}
print letters_values['A']

Also, just curious, but, how could I then have the 3 and 0 added

help(sum)
help(map)
help(int)
print int('3')
help(list)
print list('30')
help(str)
print str(30)

HTH what ?

HTH : Hope that helps

Citing your post :
"""

"""

you have the function "sumToOneDi git" that adds the digits of a number
till you get one digit (isn't that what you where curious about?)

And answering the main question : sum(ord(ch) for ch in 'chaos'.upper() )
which is inside the "sumToOneDi git" funtion in my answer.

Sorry if that is not enough for you, but the answer is probably worth
what you paid for it.

Valid when num>=1, which is guaranteed by the OP context.

Beautiful. Much better than mine.
