Correct way to detect sequence parameter?

Question

I want to write a function that accepts a parameter which can be either a sequence or a single value. The type of value is str, int, etc., but I don\'t want

Answer 1

You could pass your parameter in the built-in len() function and check whether this causes an error. As others said, the string type requires special handling.

According to the documentation the len function can accept a sequence (string, list, tuple) or a dictionary.

You could check that an object is a string with the following code:

x.__class__ == "".__class__
