Number to string

[theroflchopper]

How would I change the output of my python program from being a number to being a string. In the simplest and best way

For example: instead of 1 it being "one"

This is probably a stupid question but I can't think of anything

Hi

I think you'd have to do this the hard way. Although maybe there's a module or piece of code out there somewhere that's done it already. Probably a good idea to make a class which has the various conversions.

You'd need to make a couple of lists, and pull them out. E.g. units=['zero','one','two','three',...,'nine']. Then units[n] would give you the string.

Then you'd need to make a similar string for the teens=['eleven','twelve',...'nineteen']
A similar one for the tens=['','ten','twenty',...,'ninety'].

Then you'd have to split your number into bits (e.g. make it a string, slice it and convert the slices back to numbers), and use a serious number of if statements to put the text number together. You'll need to set an upper bound on this!!

Good advice Glenton. Let's say you put the upper limit at 9999. Without showing you a complete solution, you might set up your output like this:

    numDict1 = {0: '', 1:'one', 2:'two', 3:'three', 4:'four', 5:'five', \
                6:'six', 7:'seven', 8:'eight', 9:'nine', 10:'ten', \
                11:'eleven', 12:'twelve', 13:'thirteen', 14:'fourteen', \
                15:'fifteen', 16:'sixteen', 17:'seventeen', 18:'eighteen', \
                19:'nineteen', 20:'twenty', 30:'thirty', 40:'forty', \
                50:'fifty', 60:'sixty', 70:'seventy', 80:'eighty', 90:'ninety'
                }
    thousands, rem = divmod(num, 1000)
    hundreds, rem = divmod(rem, 100)
    tens, ones = divmod(rem, 10)

Ok but lets say I want to make a simple calculator that adds two numbers and outputs the word. I'm not sure how to incorporate the above into the output.

I would like for you to show some effort to code this for yourself. Here's a hint:

numDict1 = {0: '', 1:'one', 2:'two', 3:'three', 4:'four', 5:'five', \
            6:'six', 7:'seven', 8:'eight', 9:'nine', 10:'ten', \
            11:'eleven', 12:'twelve', 13:'thirteen', 14:'fourteen', \
            15:'fifteen', 16:'sixteen', 17:'seventeen', 18:'eighteen', \
            19:'nineteen', 20:'twenty', 30:'thirty', 40:'forty', \
            50:'fifty', 60:'sixty', 70:'seventy', 80:'eighty', 90:'ninety'
            }
 
num = 9999
 
thousands, rem = divmod(num, 1000)
hundreds, rem = divmod(rem, 100)
tens, ones = divmod(rem, 10)
 
print numDict1[thousands], "thousand"

The output:
>>> nine thousand

Yeah sor I haven't review python quite enough. I got it to work but it won't go over 21. But thanks I think I could figure it out myself now.

while True:
    import time
    print "Testing word calculator v.1"
    time.sleep(1) 
    S = input("Enter first number to be added: ")
    S2 = input("Enter second number to be added: ")
    num = S + S2
    numDict1 = {0: '', 1:'one', 2:'two', 3:'three', 4:'four', 5:'five', \
    6:'six', 7:'seven', 8:'eight', 9:'nine', 10:'ten', \
    11:'eleven', 12:'twelve', 13:'thirteen', 14:'fourteen', \
    15:'fifteen', 16:'sixteen', 17:'seventeen', 18:'eighteen', \
    19:'nineteen', 20:'twenty', 30:'thirty', 40:'forty', \
    50:'fifty', 60:'sixty', 70:'seventy', 80:'eighty', 90:'ninety'
    }
    thousands, rem = divmod(num, 1000)
    hundreds, rem = divmod(rem, 100)
    tens, ones = divmod(rem, 10)
 
    print "Your number is " + numDict1[num]

But thanks for the advice

[Glenton]

You're basically there!
You just need to build up your final number:

output=""
if thousands>0:
    output+=numDict1[thousands]+" thousand "
if hundreds>0:
    output+=numDict1[hundreds]+" hundred "
if tens>1:
    output+=numDict1[10*tens]+" "
    if ones>0:
        output+=numDict1[ones]
else:
    output+=numDict1[10*tens+ones]
 
output=output.strip()  #to get rid of trailing spaces that may be left
 

Note this gives the American way of saying numbers, which drops the "and" after hundred ("four hundred and seventeen" vs "four hundred seventeen"). If you want it the other way, you'll just have to fiddle a bit!
