Hi My cryptic subject is perhaps not sufficient - I'll try to make it a little better: Assume you'd like to write something like:
import someClass x = someClass.open("someFile") Here '.open' should read in the data and initialize the instance - with or without calling __init__. How is this to implement? Up to now I rather wrote something like x = someClass(somePrepFunction("someFile")) where the return value of somePrepFunction was used to initialize x or called the conventional 'open' within __init__. But is there no direct approach like in my pseudo-code? My problem is that if I simply define open as a method of someClass (with def open(self,file_name): #somecode pass ) all I get is: TypeError: unbound method open() must be called with someClass instance as first argument (got str instance instead) Which is perfectly understandable. But what is a possible workaround? (Instead of 'open' I could, of course, better use some other keyword which is no Python keyword.) Any hints? Thanks a lot in advance.
