x**2 ? or perhaps x^2 ? or something else like some Unicode
characters or HTML to get a small superscript 2 above an x.
Once you give an example of what your input looks like, we can start
hashing out how to read it.

Good evening,
I have converted ODT to HTML using LibreOffice Writer, because I want

Dear Gary,
thank you for the reply.
I will be more specific and take the same example that you have given
and tell you what is my problem -
array([0.0, 1.3, 2.45, 3.87, 4.54, 5.11, 6.90, 7.78, 8.23, 9.01])
from this array I want to a sub-list with lower
:
sum(map(int,str(2**1000)))
1366
Here's another one-liner using a generator instead of map:
sum(int(c) for c in str(2**1000))
