You have strings, and you want to end up with numbers. The numbers are
not integers. Other responders have gone directly to whether you should
use float or decimal as the conversion, but that is a secondary matter.
If you have integers, convert with
integer = int(number_string)
If you don't have integers, convert with
number = float(number_string)
If the number is not an integer and you need to be extremely precise
with the fractional part - for example, if you need to keep exact track
of exact amounts of money - you can use decimal instead of float. But
in this example it seems unlikely that you need that.
The thing to be aware of that hasn't been mentioned so far is that the
conversion might cause an exception if there is something wrong with one
of the number strings. If you don't handle it, your program will quit
running when it hits the error. That might not matter to you. If it
matters, you can handle the exception in the program, but first you will
need to decide what to do about such an error: should that number be
omitted, should it be replaced with a placeholder, should it be replaced
with float("NaN"), or what else?
In your case here, I'd suggest not handling the error until you get the
basics of your program working. Then if you need to, figure out how you
want to handle exceptions.

When I bring the numbers into my code, they are Strings. To use the numbers in
my code, I want to change the Strings to Float type because the code will not
work with Strings but I do not want to change the numbers in any other way.
So, I want my Strings (above) to be these numbers.
