What are descriptors? Answer: Descriptors were introduced to Python way back in version 2.2. This variable is present in the local space and not in the global space.Source: 🔹 7. These variables can be accessed by any function in the program.Local Variables: Any variable declared inside a function is known as a local variable. What are local variables and global variables in Python? Answer: Global Variables: Variables declared outside a function or in global space are called global variables.

Print "I'm meth_b"If you were to leave out the pass, the code wouldn't run and you'll get an error:IndentationError: expected an indented blockOther examples when we could use pass:Ignoring (all or) a certain type of ExceptionDeriving an exception class that does not add new behaviourTesting that code runs properly for a few test values, without caring about the resultsSource: 🔹 6. The numpy package is a good example of this, it's really quite quick because a lot of the number crunching it does isn't actually done by Python
Fortunately, Python allows the inclusion of C based extensions so bottlenecks can be optimised away and often are. Writing Python code is quick but running it is often slower than compiled languages.This means that they can be assigned to variables, returned from other functions and passed into functions. In Python, functions are first-class objects.Python does not have access specifiers (like C++'s public, private), the justification for this point is given as "we are all adults here" Python is well suited to object orientated programming in that it allows the definition of classes along with composition and inheritance.You can do things like x=111 and then x="I'm a string" without error Python is dynamically typed, this means that you don't need to state the types of variables when you declare them or anything like that.Other interpreted languages include PHP and Ruby. That means that, unlike languages like C and its variants, Python does not need to be compiled before it is run.
