convert a list with decimal number and data type to just numbers

My return result from my database looks like :

a = [Decimal('0.4441'), Decimal('0.3821'), Decimal('0.4414'), Decimal('0.3391')]

How can I convert it to :

a = [0.4441, 0.3821,  0.4414, 0.3391]

Try to use the index 0, as in: for i in a: print(i[0])

this will get rid of the "extra information" and will only leave you your number (in decimals).

>>> from decimal import Decimal
>>> a = [Decimal('0.4441'), Decimal('0.3821'), Decimal('0.4414'), Decimal('0.3391')]
>>> a = [float(n) for n in a]
>>> a
[0.4441, 0.3821, 0.4414, 0.3391]

I don't see why you would want to do this, you are just losing precision.
