I'm going to explain why this confusion between classes and functions happens in Python and then explain why this distinction often doesn't matter.If you'd rather watch a 2 minute summary, see The meaning of "callable" in Python". Also see the callable definition in Python Terminology. ...
being able to spell argument names and kinds is useful in the absence of such a thing. I'll write it up separately once we know what the fate of variadic type variables is likely to be (since the exact definition/meaning of OtherArgs depends on whether we can explain it with variadic ...
in some cases, the module name and function name may be the same. For example, thegetoptmodule provides thegetopt()function, which may create confusion. Callable means that a given python object can call a function, but in this error, we warned that a given ...
Whenever we writea programin Python we should never consider using a registered keyword or function name as a new variable. To solve the above program all we need to do is change the name ofstrvariable to something else which is not a reserved keyword and provide more meaning to the variab...
In particular callable classes are not supported. For now you can only provide import paths to functions. Class A is not a callable. The instances of class A are callable. A type hint that would work now would be Sequence[A] meaning a sequence of instances of any subclass of A, i.e....
Curly brackets in Python have a special meaning. They are used to denote a function invocation. If you specify a pair of curly brackets after an integer without an operator between them, Python thinks you’re trying to call a function. This will return an “TypeError: ‘int’ object is ...

Encountered an error of TypeError with ' numpy.ndarray ' object is not callable , but I'm clueless about its meaning. Currently, I'm watching a tutorial video at https://www.youtube.com/watch?v=tNa99PG8hR8. The objective is to develop a basic machine learning program that utilize...
To look up their meaning in the manual, is there some method less clumsy than grepping the whole collection of .html source files? I can't find any comprehensive index. Here's the index of the reference manual: 404 Not Found http://docs.python.org/ref/genindex.html Ciao, Marc '...
