[Tutor] constructors

[Erik Price]

When writing a class, is it recommended to always take advantage of 
constructors?  I have written a class called Person, which helps me to 
organize my user-input error-checking (by confining error-checking 
functions to the methods that set instance attributes).  I don't have a 
constructor, because sometimes I use this class to build a new Person 
and sometimes I use this class to pull an already-existing Person's 
attributes from a database table.  But constructors are seen as a 
"really good thing", but as far as I can see a constructor is just a 
shortcut.  Please share your thoughts on using constructors, if you 
would?


Thank you,

Erik
