is there an equivalent of the setdiff() R function in the python library pandas ?
I need to replicate a function like setdiff(x, y) that one can find in R!

1There is a datatype `set` in python generally supporting usual set operations. – Kay Wittig Jul 17 '18 at 19:24

Thanks ! Sorry for reasking but how do I cnvert it from a set to a list again ? set seems like a dict....:-) – Andrea Ferrante Jul 17 '18 at 19:27

1@AndreaFerrante set is not like a dictionary because there are no key-values pairs, just sets of values and you convert it to a list like this `list(a)` – Hack-R Jul 17 '18 at 19:28
