unsupported operand type(s) for *: 'dict' and 'float'

This error occurs when you try to multiply a dictionary object with a float or any other incompatible data type. Dictionaries are not designed to support mathematical operations like multiplication.

For example:

my_dict = {'a': 1, 'b': 2, 'c': 3}
result = my_dict * 2.0

This code will raise the "unsupported operand type(s) for *: 'dict' and 'float'" error because you cannot multiply a dictionary with a float.

To fix this error, you need to use the appropriate data type for multiplication. If you want to multiply the values in the dictionary with a float, you need to loop through the dictionary and perform the multiplication operation on each value individually.
