Python is an object-oriented and high-level programming language and getting more popular nowadays because of its dynamic nature, versatility, and ease to learn. Python is the second most preferred programming language after JavaScript and it can be used in any field like Artificial Intelligence, Machine learning, Deep learning, and Web Development.
In this article, we are going to see 15+ advanced python concepts that you must know if you are a python developer. If you want to learn python programming or you are a python developer then you must know these python advanced concepts. So let's start this article without wasting any time:
Table Of Contents
1. lambda Function
A lambda is a small anonymous function that can take any number of arguments but can only have one expression. A general python function is defined using the style of def function_name(), but with the lambda function, we don't give it a name. The Lambda function is very important because the purpose of this function is to perform some kind of simple and operational expression without the need for fully defining a function.
The Syntax of Lambda Function:
lambda arguments : expression
2. Map Function
Python programming has a built-in function called map() which returns a map object(which is an iterator) of the results after applying the given function to each item of a given iterable(tuple, list or dict, etc.). The map function is most importantly a readable way to perform such an operation.
The syntax for Map Function:
map(function, iterable)
3. Filtering
The filter is also a python built-in function which is quite similar to the Map function. The main difference between map() and filter() is that the filter function only returns the filtered elements as True from a given sequence.
The Syntax of Filter Function:
filter(function, itertools)
4. Generator
A generator function is used to allow you to declare a function that behaves like an iterator and it also allows programmers to make an iterator in an easy and fast way. A generator is a special type of function in python programming which does not return a single value instead it returns an iterable generator object. In the generator, the function yield statement is used rather than the return statement.
