I have a python list with strings in this format:

A1 = [' "29.0" ',' "65.2" ',' "75.2" ']

How do I convert those strings into decimal numbers to perform arithmetic operations on the list elements?

If you want the result as the nearest binary floating point number use float:

result = [float(x.strip(' "')) for x in A1]

If you want the result stored exactly use Decimal instead of float:

from decimal import Decimal
result = [Decimal(x.strip(' "')) for x in A1]
