A namespace is basically a system to make sure that all the names in a program are unique and can be used without any conflict. You might already know that everything in Python—like strings, lists, functions, etc.—is an object. Another interesting fact is that Python implements namespaces...
Slicing in Python gets a sub-string from a string. The slicing range is set as parameters i.e. start, stop and step. For slicing, the 1st index is 0. For negative indexing, to display the 1st element to last element in steps of 1 in reverse order, we use the [::-1]. The [:...
The reason MockObject is incompatible with sequence unpacking is due to a limitation of operator overloading in python when it comes to this piece of syntax. Let's take a look at how the failing line compiles: >>>importdis>>>dis.dis(compile("a, b = fake","string","exec"))1 0 ...
