Sorry, you really can't give FunctionType an argument list.
Maybe you can wrap the function with a callable object, this way you can
change the argument list returned, and doest have to eval or compile code.

You can use the FunctionType class found in the types module (and its
friends) to create functions on the run.
And you can use the 'inspect' module to inspect existing functions, if you
need to base the new function on an existing one.

Hi Gal,
Seems the types module docs do not even have

I have a class factory where I dynamically add a constructor to the class
output.
The method is a closure and works just fine, however to accommodate the varied
input its signature is (*args, **kwargs).
While I modify the doc strings, the ctor sig is not optimal. Without building
this a string an
12 matches
