1. Local Variables in Python A variable that is declared inside a Python function or module can only be used in that specific function or Python Module. This kind of variable is known as a local variable. Example: Python 1 2 3 4 5 6 7 8 9 a=100 print (a) def some_function()...

Class or Static variables are shared amongst objects of the class. All variables which are assigned a value in the class declaration are class variables. And variables which are assigned values inside class methods are instance variables.Let's have an example to understand this:...
Parse a string to receive day, month and year as three integer variables or a 3-item tuple consisting of that variable. InstantiateDateby passing those values to initialization call. This will look like: day, month, year = map(int, string_date.split('-')) ...

Furthermore, the inner functions aren’t defined until the parent function is called. They’re locally scoped to parent(), meaning they only exist inside the parent() function as local variables. Try calling first_child(). You’ll get an error:...
