Map Function

As you are all aware, the Python programming language includes a function called map that allows you to process all of the elements in an iterable without explicitly using a looping construct. It then returns a map object, which is an iterator.

The map object obtained is the result of applying the specific function to each item in the iterable.

This is one of the advanced python concepts that all programmers should know.

Itertools

Python has a fantastic standard library called itertools, which contains a number of functions that aid in the creation of fast, clean, and memory-efficient code.

Itertools functions operate on iterators, which in turn return more complex iterators such as repeat, count, cycle, accumulate, permutations, product, and combinations.

This is one of the advanced Python concepts that programming experts can employ.

You will be able to generate results faster than the traditional method if you use this Python programming language.

Lambda Function

Lambda functions in Python are small, anonymous functions that do not have a name and are maintained in a single line of code.

For example, the keyword 'def' is used to define functions, but it is defined here as the keyword 'lambda'.

When you only need to use a function once, this technique can make it easier to read and use the code.

Python concepts will be beneficial to programmers.

Exception Handling

Exceptions are types of errors that can occur during programme execution and disrupt the normal flow of the programme. For example, dividing a number by zero.

In Python, we use except, try, and finally to handle exceptions.

This is one of the advanced python concepts that programmers can employ.

Whereas try is used to wrap a block of code that can set aside errors, except is used to wrap a block of code that will be executed when an exception occurs, and finally allows you to execute the code regardless of what happens.

Decorators

These are examples of Python metaprogramming, which is used to add new functionality to existing code without changing the original structure at compile time. This is more akin to a regular Python function known as returns.

It can function, modify and add functionality, and then return it.

Python concepts will be beneficial to programmers.

Collections

Python collections are built-in general-purpose containers such as tuples, sets, dictionaries, and lists. These collections are a type of module that implements various container data types.

This includes named tuple, a function for creating tuple subclasses with named fields, and OrderedDict, a dict subclass that remembers the order entries that were added because programming dicts are not ordered.

Generators

Generators are a type of function in Python that, instead of returning a single value, returns an iterator object that is a sequence of values.

Generators are the tools that allow you to write your own iterator functions.

The difference between yield and return is that the former eliminates the function, whereas the latter only pauses the function's execution and returns the value against it each time.
