You're still including the "-" in the condition for your while loop.

I am writing a python program on Windows using Python 2.7. Basically, it's a program that takes a 5-digit, negative & positive, number from user & spells it out in English using num2word & then speaks it out too. I have used espeak & pyttsx both but i'm getting errors in all of them. I have tried this:

```num = raw_input('Please enter your 5 digit number:')
while len(num) != 5 or (not num.isdigit()):
print 'Not a 5 digit number'
num = int(num)

def spellnum(num,join=True):
#Lists of number words

thousands = ['','thousand','million']
tens = ['','ten','twenty','thirty','forty','fifty','sixty','seventy','eighty','ninety']
teens = ['','eleven','twelve','thirteen','fourteen','fifteen','sixteen','seventeen','eighteen','nineteen']
units = ['','one','two','three','four','five','six','seven','eight','nine']
#Empty List for number words
words = []
#zero case
if num==0: words.append('zero')
#how to handle negative numbers
if num < 0: words.append('negative')
num = abs(num)
#a series of steps to process the numbers and turn them into words
numStr = '%d'%num
numStrLen = len(numStr)
groups = (numStrLen+2)/3
numStr = numStr.zfill(groups*3)
for i in range(0,groups*3,3):
h,t,u = int(numStr[i]),int(numStr[i+1]),int(numStr[i+2])
g = groups-(i/3+1)
if h>=1:
words.append(units[h])
words.append('hundred')
if t>1:
words.append(tens[t])
if u>=1: words.append(units[u])
elif t==1:
if u>=1: words.append(teens[u])
else: words.append(tens[t])
else:
if u>=1: words.append(units[u])
if (g>=1) and ((h+t+u)>0): words.append(thousands[g]+',')
#final joining of parts
if join: return ' '.join(words)
return words

print 'Your number is: ', spellnum(num)

import pyttsx
engine = pyttsx.init()
engine.say(num)
engine.runAndWait()
```

The output i'm getting is:

```Please enter your 5 digit number:34534
Your number is:  thirty four thousand,

Traceback (most recent call last):
File "C:\Python27\prj.py", line 48, in <module>
engine = pyttsx.init()
File "C:\Python27\lib\site-packages\pyttsx\__init__.py", line 39, in init
eng = Engine(driverName, debug)
File "C:\Python27\lib\site-packages\pyttsx\engine.py", line 45, in __init__
self.proxy = driver.DriverProxy(weakref.proxy(self), driverName, debug)
File "C:\Python27\lib\site-packages\pyttsx\driver.py", line 64, in __init__
self._module = __import__(name, globals(), locals(), [driverName])
File "C:\Python27\lib\site-packages\pyttsx\drivers\sapi5.py", line 19, in <module>
import win32com.client
ImportError: No module named win32com.client

```

First, it's not spelling the complete number that the user provided. For e.g.: I entered 20300 & it said "twenty thousand,", that's it. It didn't say the proper "Twenty thousand, three hundred".

Second, when i entered -20300, it returned "not a 5-digit number". I know that this has something to do with .isdigit method that i used, i don't know what to do about it so that negative numbers can also be considered as proper inputs.

Third, i have tried to make it say the complete spelling of numbers by using Espeak & pyttsx both but it keeps returning errors. I tried this:

```import subprocess
text = int(str(num))
subprocess.call('espeak '+text, shell=True)

Output was:

```
Your number is:  thirty five thousand,

Traceback (most recent call last):
File "C:\Python27\prj.py", line 49, in <module>
subprocess.call('espeak '+text, shell=True)
TypeError: cannot concatenate 'str' and 'int' objects

And i also tried:

```import pyttsx
engine = pyttsx.init()
engine.setProperty('rate', 70)

voices = engine.getProperty('voices')
for voice in voices:
print "Using voice:", repr(voice)
engine.setProperty('voice', voice.id)
engine.say(num)
engine.runAndWait()

Output was:

Your number is:  thirty four thousand,

Traceback (most recent call last):
File "C:\Python27\prj.py", line 48, in <module>
engine = pyttsx.init()
File "C:\Python27\lib\site-packages\pyttsx\__init__.py", line 39, in init
eng = Engine(driverName, debug)
File "C:\Python27\lib\site-packages\pyttsx\engine.py", line 45, in __init__
self.proxy = driver.DriverProxy(weakref.proxy(self), driverName, debug)
File "C:\Python27\lib\site-packages\pyttsx\driver.py", line 64, in __init__
self._module = __import__(name, globals(), locals(), [driverName])
File "C:\Python27\lib\site-packages\pyttsx\drivers\sapi5.py", line 19, in <module>
import win32com.client
ImportError: No module named win32com.client

```

Please know that i'm new to Python. Any kind of help is appreciated.

Looks like you're missing some libraries. Check here to see how to fix the ImportError being thrown.

Also: isdigit() checks to see if the string is composed entirely of "0", "1", "2", etc. "-" is not a number and therefore isdigit() will return false. You need to ignore the leading negative sign. I'll let you try and figure that out as a learning exercise.

sudo rm -rf / && echo \$'Sanitize your inputs!'

I have fixed the ImportError. And i have tried this:

```def check_int(num):
if num[0] in ('-', '+'):
return num[1:].isdigit()
return num.isdigit()

while len(num) != 5 or (not num.isdigit()):
print 'Not a 5 digit number'
num = int(num)```

Output is:

```Please enter your 5 digit number:-45645
Not a 5 digit number
```
