I need delete Decimal('') from result.

When I run program This is result.

{'DEN': {'c9': Decimal('23.625'), 'c18': Decimal('22.625'), 'c3': Decimal('19.312'), 'c12': Decimal('23.062'), 'c0': Decimal('20.687'), 'c6': Decimal('19.75'), 'c15': Decimal('21.875')}}

Answer 1

Convert them to float:

hodnoty_databaza['DEN'] = {x:float(y) for x,y in hodnoty_databaza['DEN'].items()}
print hodnoty_databaza['DEN']
# {'c9': 23.625, 'c18': 22.625, 'c3': 19.312, 'c12': 23.062, 'c0': 20.687, 'c6': 19.75, 'c15': 21.875}
