Hi shwetad , 
 
there is no in-built function to verify weather it is a user or group.I think you can make a use of typeof() function to check this 
or 
runtimetypeof -->This function returns runtime type of variable. 
 
Thanks

Hi You can use runtimetypeof function 
 
if(runtimetypeof(topeople(loggedInUser())) = type!User, "You're a User", "You're a Group") 
returns You're a User

Hi shwetad 
 
Using typeof function is the simplest solution to this problem. But you can also check weather it's first character is "[" or not if yes then it's group else user.
