Hello,
I have code that works. Then tried to move some of it into function
IncrementAndRebuildInput, then result changes, I no longer have same result
as when code in function was inline - why?
Have you tried running it in isolation to see what it does?
When I try it, it works for me (apart from printing a lot of unnecessary
intermediate results):
py> result = IncrementAndRebuildInput("abc def 123 xyz 456")
['abc', 'def', '123', 'xyz', '456']
124
['abc', 'def', '124', 'xyz', '456']
NOWHERE
457
['abc', 'def', '124', 'xyz', '457']
NOWHERE
['abc', 'def', '124', 'xyz', '457']

Now check the returned result:
py> result
['abc', 'def', '124', 'xyz', '457']
So it certainly does increment the numbers in the string. The only
bit it doesn't do is rebuild the string, but that takes just one
minor change: instead of "return newstring" (by the way, that's false
advertising -- newstring is not a string, it is a list), use:
return ' '.join(newstring)
You also use this function:
def IsNum(string):
# print "IsNum string", string
for char in string: #checks string groupings to be all nums
if not char.isdigit():
# print "false"
return False
# print "true"
return True
You don't need it! The isdigit method doesn't only work on a single character
at a time, it works on an entire string:
py> "12345".isdigit()
True
py> "12345a".isdigit()
False
