You are trying to access a part of the string that doesn't
exist. In this case the first character. It will work if you
don't call it with an empty string.

If you are certain that your function is always called
with a string, you can do this:

if (not text) or (not text[0].isdigit()):
     #handle empty string or non-numeric
     return text
...
