Re: How to create functors?

Lambda expressions are, I believe, syntactically limited to a single expression -- no statements, like 'print' is in Python 2.x. If you are strongly against just defining a function, you might have to use a trick to get around it -- this page (http://p-nand-q.com/python/stupid_lambda_tricks

How to create functors?

Hello, I want to simply wrap a function up into an object so it can be called with no parameters. The parameters that it would otherwise have taken are already filled in. Like so: print1 = lambda: print( "Foobar" ) print1() However, the above code fails with: File "C:\IT\work\dis

I want a dictionary that will transparently "inherit" from a parent dictionary. So, for example: """ a = InheritDict({1: "one", 2: "two", 4: "four"}) b = InheritDict({3: "three", 4: "foobar"}, inherit_from=a) a[1] # "one" a[4] # "four" b[1] # "one" b[3] # "three" b[4] # "foobar" """ I've written
