Hello,

I have a question pertaining to Python. I have been using the online book "How To Think Like A Computer Scientist" and have been doing the questions at the end of the chapters.

I cannot figure out how to modify "num_digits" so that it works as expected.I have tried and cannot seem to get it to work. I had been working pretty well in Python up to this point. I am given this:

[def num_even_digits(n):

"""

>>> num_even_digits(123456)

3

>>> num_even_digits(2468)

4

>>> num_even_digits(1357)

0

>>> num_even_digits(2)

1

>>> num_even_digits(20)

2

"""]

Any help would be appreciated.

Thanks!
