In this first example, we will use themap()function to iterate through string_list and replace the strings with float numbers, which results in a new list called float_list. After the implementation, we will test the data types of elements in float_list via thetype()function inside afor ...
('22.90'), currency='€') >>> price.amount # numeric price amount Decimal('22.90') >>> price.currency # currency symbol, as appears in the string '€' >>> price.amount_text # price amount, as appears in the string '22,90' >>> price.amount_float # price amount as float, not...
If you forget to make this change, you will see errors about FloatField not taking a max_digits attribute in __init__, because the new FloatField takes no precision-related arguments. If you’re using MySQL or PostgreSQL, no further changes are needed. The database column types for Decima...
