This is the old way of using string functions using the module string. You
should only write this as:
mynumArray = mynums.split(".")
(using the string methods of string objects directly)

This is misleading. Rename the variable to num, as it only contains a single
number.

.isalnum() checks whether the string consists of _alpha_-numeric characters
only. So, in this case, it may contain letters, among digits. .isdigit()
checks whether it is a (base <= 10) number.

As you don't know what the offending element is, insert a:
print nums
here.

If you change the code as noted above, it works fine for me.
