unsupported operand type(s) for &: 'int' and 'float'翻译

This error message typically occurs when a Python program attempts to perform an operation that is not supported on a particular data type. For example, if you try to add a string and a number together, you will get an "unsupported operand type(s)" error because Python does not know how to add a string and a number together.

Here is an example of the error message in action:

>>> x = "hello"
>>> y = 42
>>> z = x + y
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'str' and 'int'

In this example, Python is telling us that we cannot add a string and an integer together using the `+` operator. To fix this error, we would need to convert one of the operands to the correct data type, or use a different operation that is supported by both data types.
