use isinstance v  type name  or type v  is type name or type v     type name    where type name can be one of the following    None bool int float complex str list tuple set dict   and  of course     custom types  classes

What type   means  I think your question is a bit more general than I originally thought  type   with one argument returns the type or class of the object  So if you have a    abc  and use type a  this returns str because the variable a is a string  If b   10  type b  returns int  See also python documentation on type     For comparisons  If you want a comparison you could use  if type v     h5py h5r Reference  to check if it is a h5py h5r Reference instance   But it is recommended that one uses if isinstance v  h5py h5r Reference  but then also subclasses will evaluate to True  If you want to print the class use print v   class     name    More generally  You can compare if two instances have the same class by using type v  is type other v  or isinstance v  other v   class
