> The __eq__ method of the
> [PrimitiveSchema|https://github.com/apache/avro/blob/master/lang/py3/avro/schema.py#L629],
> EnumSchema and FixedSchema assume that the compared object has an attribute
> called "props" which makes a statement like this (for example) throw an
> exception:
> {code:python}
> o = PrimitiveSchema(...)
> if o == "null":
> print("Not same")
> {code}
>
> The exception message looks like:
> {code:bash}
> AttributeError: 'str' object has no attribute 'props'
> {code}
> A more robust equals method would start by ensuring type equality before
> doing other comparisons. Alternatively (though less pretty) the way the other
> Schema types implement it could be used, for example
> [ArraySchema|https://github.com/apache/avro/blob/master/lang/py3/avro/schema.py#L772]
