itermonthdates() method will return all days for the month and all days before the start of the month or after an end of the month that are required to get a complete week. Example import calendar #assigning variable to the calendar variable = calendar.Calendar() for day in variable.iter...
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...

Just as for function annotations, the Python interpreter does not attach any particular meaning to variable annotations and only stores them in the __annotations__ attribute of a class or module. In contrast to variable declarations in statically typed languages, the goal of annotation syntax is ...
There are many more iterators in Python besides enumerate and zip. Every iterable is either an iterator itself or can be converted into an iterator using iter().However, in this section, you’ll explore Python’s itertools module, which has several of these data structures. You’ll learn ...
New function: itertools.combinations_with_replacement(iter, r) returns all the possible r-length combinations of elements from the iterable iter. Unlike combinations(), individual elements can be repeated in the generated combinations: itertools.combinations_with_replacement('abc', 2) => ('a', '...
In this tutorial, you will learn about namespaces and their importance. You will also learn about different ways of importing an external module in Python and the reasons to choose one method over ano
