The suggestion therefore is:
def __init__(self, foo, bar, baz, spam, ham): self .= foo, bar, baz, spam, ham
This is purely syntactic sugar for the original example:
def __init__(self, foo, bar, baz, spam, ham): self.foo = foo self.bar = bar self.baz = baz self.spam = spam self.ham = ham
... so if any of the attributes have setters, then they are called as usual. It's purely a syntactic shorthand. Any token which is not suitable on the RHS of the dot in a standard "obj.attr =" assignment is a syntax error (no "self .= 1").
Bikeshedding: Your example looks a lot more like tuple assignment than multiple assignment. I'd rather it link more with the way that multiple assignment works: # simple multiple assignment a = b = c = d = e = 0 # object member assignment self .= foo .= bar .= baz .= spam .= ham The trouble is that this syntax is really only going to be used inside __init__. It's hard to justify new syntax for one purpose like this. So I'm swaying between -0 and +0.5 on this. ChrisA
