This is because str(range(10)) does not do what you think it does.

In python 2.x, str(range(10)) creates a string representation of the 
complete list, not a list of the string representation of the separate 
list elements. '[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]'

In python 3.x, str(range(10)) creates a string representation of the list 
object. 'range(0, 10)'

the only single digit strings in the python3 representation are "0" and 
"1"

To recreate the python2 behaviour in python 3, use:

str(list(range(10)))

which gives

'[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]'

howver the test:

if x.isdigit():

is much better.

But finally, with your telephone number decoder, look at:
