Re: What is not objects in Python? Terry Reedy: Partly history and partly practicality. Len is implemented as .__len__ ;-). The len function is one, __len__ methods are many. If you want to pass an argument to a function, passing len is easier that passing operator.attrge tter(...
The syntax which allows a comma separated series of names on the left to unpack the value on the right is known assequence unpackingin python. The reason MockObject is incompatible with sequence unpacking is due to a limitation of operator overloading in python when it comes to this piece o...

attr and jq are common utilities and are available via the package manager. skopeo has only recently been packaged for common Linux distros. If you don't see your distro in the list, your best bet is building from source, which is reasonably straightforward if you have Go installed. For ...
What is tail-recursion Consider a simple function that adds the first N integers. (e.g.sum(5) = 1 + 2 + 3 + 4 + 5 = 15). Here is a simple Python implementation that uses recursion: defrecsum(x):ifx == 1:returnxelse:returnx + recsum(x - 1)...

in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
