All,
Once again thanks for all the suggestions. It was the input data after all. As
I am importing three sheets into python. One of the sheets had one less column.
Thus how I ended up with float points. The testing for the string helped here
greatly. Now things are correct again.
On and forward to start working on text pattern exercise which I always have
struggled with. Last language I did this in was Perl and had all sorts of
headaches. 😊 Python seems cleaner from the reading I have done thus far. Lets
see what challenges wait in front of me.

So, fairly obviously, we can't test whether a float is less than a string. Any
more than we can tell if a grapefruit is faster than a cheetah. So there must
be items in description that are strings and floats.
With 2000 lines, you're going to struggle to eyeball this, so try something
like this:
In [69]: irrational_numbers = [3.14159265, 1.606695, "pi", "Pythagoras
Constant"] In [70]: from collections import Counter In [71]:
dict(Counter([type(e) for e in irrational_numbers]))
Out[71]: {float: 2, str: 2}
If with your data, this shows only strings, I'll eat my hat.
S.
