`type("") == str`. However, this may not be necessary/wise/etc. – Fiddling Bits Aug 17 '22 at 19:18

@FiddlingBits **no** that is absolutely not how you should be doing that – juanpa.arrivillaga Aug 17 '22 at 20:12

In Python, the recommended way is to do it with isinstance(), so to see the type of var:
isinstance(var, str)
Alternatively, you can do it with type():
type(var)
Using the second way, in a more specific context, if you want to know if var is a string, you can do it this way:
type(var) == str

What do you mean? My code is correct, and it works, however, if you think it can be improved please edit it as you see fit. – Dennis Kozevnikoff Aug 17 '22 at 20:39

I said what I meant, it is not idiomatic. Idiomatically, you would do `isinstance(var, str)`. – juanpa.arrivillaga Aug 17 '22 at 20:56
