Python is a dynamic, high-level programming language that enables developers to write code more quickly than with other languages, like C. It was conceived in the end of 1989 by Guido van Rossum and has interested many people around the world because of its simplicity and extensibility. Python offers some very good features when working with text data, which is its main use case for machine learning, web scraping, natural language processing, etc. The article will start with the most basic constructs in Python so it’s accessible to anyone that hasn’t done any programming or hasn’t programmed in years. Afterwards I will talk about more powerful features of Python for everyone that already has some basics in programming. "

Basic Python
Functions
A function is a self-contained unit of code that is usually executed as a whole. Functions are very important in Python and are used in most programming languages. You can use them to create algorithms that can be reused. They can also be used to organize your code in a clean and logical way.
Functions can be used to create sub-functions. This is a special type of function that contains a function as a sub-function. They can be nested to any level.
Functions can be defined in the same file as the calling function. This makes them accessible to the calling function.
Loops
A loop is a mechanism to repeat a certain block of code. Loops can be used to repeat code over and over. The block of code can be any type of code, from one line of code to a large block of code.
Python offers a few types of loops. You can use the for loop to repeat code over and over. The code block will be executed multiple times.
The for loop is the most basic loop in Python. It is a for loop.
There are two types of for loops:
for (initialization) loop: looping until the condition becomes false.
for (condition) loop: looping until the condition becomes true.
If the condition is true, the loop continues
Classes
A class is a special type of object. Objects are used to store data. Classes can be used to group similar data together.
Classes can be defined in the same file as the calling function. This makes them accessible to the calling function.
Classes can be used to create objects. Objects are used to store data.
Python offers two types of classes:
Simple class: defines one or more data attributes
Abstract class: defines an abstract data type.
When defining a class, you must define at least one data attribute.
A data attribute is an attribute of a class that stores data.
A class can have more than one data attribute.
Abstract classes can be used to
Variables
Variables are used to store data. Variables are used to store data that will be used in a program.
You can use variables in Python in a few ways. The first is by defining a variable. This is done by using the var keyword. The second is by accessing a variable.
The first way to use variables is to define them.
The var keyword is used to define a variable.
The second way to use variables is to access them.
The var keyword is used to access a variable.
Python also offers other ways to use variables.
Numbers
Numbers are used to store data. Numbers are the smallest type of data in Python. They can be used to represent the
Flow Control
Python offers two types of flow control:
while: repeat code while a condition is true.
if: repeat code if a condition is true.
Python offers several ways to use flow control. The first is the while loop. The second is the if statement.
The while loop is used to repeat code while a condition is true.
The if statement is used to repeat code if a condition is true.
Python offers two ways to use the if statement:
if test: code to execute if test is true
if test else code to execute if test is true
The if statement can be used to repeat code if a condition is true.
The if statement can be used to repeat code if a
Strings
Strings are used to store data. Strings are used to store data that can be used to represent a character. They are also used to represent a piece of text.
You can use strings in Python in several ways. The first is by defining a string. This is done by using the str keyword. The second is by accessing a string.
The first way to use strings is to define them.
The str keyword is used to define a string.
The second way to use strings is to access them.
The str keyword is used to access a string.
Python also offers other ways to use strings.
Lists
Lists are used to store data. Lists are used to store data that can be used to represent a collection of items.
You can use lists in Python in two ways. The first is by defining a list. This is done by using the list keyword. The second is by accessing a list.
The first way to use lists is to define them.
The list keyword is used to define a list.
The second way to use lists is to access them.
The list keyword is used to access a list.
Python also offers other ways to use lists.
Dictionaries
Dictionaries are used to store data. Dictionaries are used to store data that can be used
