background information. The same thing will happen when you learn the Python programming language with DataFlair.<\/p>\n<p>While you move from one Python topic to another, do take time to make notes and jot down information that you will require for the long-term. This has proven beneficial for users who are aiming to become full-time developers.<\/p>\n<p>Imagine this as your launchpad. From learning the basic strings and lists to learning big ideas like classes and functions, you have gained a vast knowledge that can help you create anything with Python.<\/p>\n<p>With these strategies, you are ready to learn Python.

Python basic tutorial<\/h4>\n<p>It covers a <a href=\"https:\/\/data-flair.training\/blogs\/python-tutorial\/\"><strong><em>general introduction of the Python language<\/em><\/strong> <\/a>with its key features, architecture, and applications.<\/p>\n<p>It will provide you with answers to questions like- why choose Python and what its future holds.<\/p>\n<p><em><strong>For further reference <\/strong><\/em><br \/>\n<em><a href=\"https:\/\/data-flair.training\/blogs\/features-python\/\"><strong>-Features<\/strong><\/a><\/em><br \/>\n<em><strong><a href=\"https:\/\/data-flair.training\/blogs\/python-applications\/\">-Applications<\/a><\/strong><\/em><br \/>\n<em><strong><a href=\"https:\/\/data-flair.training\/blogs\/python-career-opportunities\/\">-Future opportunities<\/a><\/strong><\/em><\/p>\n<p style=\"text-align: center\"><span style=\"color: #ff6600\"><strong><span style=\"color: #ff0000\">WAIT!<\/span>\u00a0Is your Python setup ready to practice the concepts simultaneously? Still not????<\/strong><\/span><\/p>\n<p style=\"text-align: center\"><span style=\"color: #ff6600\"><strong>Check out DataFlair&#8217;s 5Mins <a href=\"https:\/\/data-flair.training\/blogs\/install-python-windows\/\">Python Environment Setup Guide<\/a> to start with<\/strong><\/span><\/p>\n<h4>2. Python syntax<\/h4>\n<p>To learn any language, not only technical but any language in general, one has to have a strong command of its grammar. Grammar in a technical scenario means syntax. It will demonstrate to you how <a href=\"https:\/\/data-flair.training\/blogs\/python-syntax-semantics\/\"><em><strong>Python\u2019s syntax<\/strong><\/em> <\/a>is different than Java and C++.<\/p>\n<p>You will unfold the use of different identifiers and variables, and also how they are different from each other.<\/p>\n<h4>3. Python statements, indentation, and comments<\/h4>\n<p>As you are getting used to Python and its syntax, you can move forward with the next level of understanding, i.e., statements and indentation.<\/p>\n<p><a href=\"https:\/\/docs.python.org\/3\/tutorial\/index.html\">Python<\/a> overall is not considered a strict language to follow; the only thing that needs to be taken care of is the indentation. It increases its reliability and effectiveness.<\/p>\n<p>Throughout the journey of learning Python, conditional statements like \u2018if\u2019, \u2018for\u2019, \u2018while\u2019, etc., will be observed, constructing the logical code for the given problem.<\/p>\n<p>Whereas \u201cPython comments\u201d will be used for understanding the code written by the coder, and making changes accordingly.<\/p>\n<p>Hence, a good hold of \u201ccomments\u201d might not help you in coding, but will improve your presentation skills of the code when you present it in front of its target audience.<\/p>\n<h4>4. Python variables and data types<\/h4>\n<p>To give a general idea, we don\u2019t specify the type of a variable when declaring one also there are some set of rules of naming a variable.<\/p>\n<p>Although we don\u2019t declare the type of data, a value certainly has a type that is previously known to the <em><strong><a href=\"https:\/\/data-flair.training\/blogs\/python-interpreter\/\">interpreter<\/a><\/strong><\/em>. It includes- integer, float, long, complex, etc.<\/p>\n<h4>5. Python Operators<\/h4>\n<p>It is responsible for performing various mathematical and logical operations in the code. The operand is a value on which the operation is performed.<\/p>\n<p>7 main categories are present in which operands are divided for proper programming, from Arithmetic, Relational, Assignment, Logical, Bitwise, Comparison, Membership, Identity, etc.<\/p>\n<p>So, in the journey of learning Python, <strong><a href=\"https:\/\/data-flair.training\/blogs\/python-operator\/\">Python Operators<\/a><\/strong> play a major role.<\/p>\n<h4>6. Python Numbers<\/h4>\n<p>An entity that lets you measure something is termed a number.<\/p>\n<p>It will allow you to dig a little deeper into the <em><strong><a href=\"https:\/\/data-flair.training\/blogs\/python-number-types-conversion\/\">number types of Python<\/a><\/strong><\/em>, i.e., int, float, complex numbers, and so on.<\/p>\n<p>Programmers often deal with numbers in binary, octal, and hexadecimal, and their interconversion.<\/p>\n<h4>7. Python Strings<\/h4>\n<p>It will cover the <a href=\"https:\/\/data-flair.training\/blogs\/python-string\/\"><em><strong>general introduction of a string<\/strong><\/em><\/a> ( a sequence of characters ) and its examples.

Python Data Structures<\/h4>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/python-data-structures-tutorial\/\"><em><strong>Different data structures of python<\/strong><\/em><\/a> will be covered that includes list, tuple, and dictionaries.<\/p>\n<p>It is nothing but a way of organizing, storing, and accessing data.<\/p>\n<p>According to their advantages and disadvantages, one can decide which data structure will be suitable.<\/p>\n<h4>9. Python List<\/h4>\n<p>How to create, access, slice, and re-assign <a href=\"https:\/\/data-flair.training\/blogs\/python-lists-examples\/\"><em><strong>list in Python<\/strong><\/em><\/a> will be discussed. Also, how to apply functions to them by covering various operations and concatenation.<\/p>\n<p>A general idea of the list will be provided in the Data structures, here you will come across a detailed study.<\/p>\n<p>Learn how to delete or reassign elements or lists and some built-in functions and methods.<\/p>\n<h4>10. Python Tuples<\/h4>\n<p>A deeper look than that of the Data Structure material and insights into how to create, access, slice, and delete <em><strong><a href=\"https:\/\/data-flair.training\/blogs\/python-tuples-syntax-examples\/\">tuples<\/a><\/strong><\/em>. Also, look into built-in functions, methods, and operations that can be called on a tuple.<\/p>\n<p>Before moving forward to the next level of learning Python, take a while to understand the building blocks of the Python language.<\/p>\n<p>You do not need to learn \u201call\u201d the Python syntax before you start to do something interesting with it, but you <em><strong>should have a good hold on the basics mentioned above<\/strong><\/em>.<\/p>\n<p>But don\u2019t spend months on it; with practice and a good revision plan, one can easily grasp the concepts.<\/p>\n<h3>Learn Python Intermediate Level Topics<\/h3>\n<p>The next level in learning Python is the intermediate level. So, let&#8217;s start exploring Python notes &#8211;<\/p>\n<h4>1. Python Module<\/h4>\n<p>Learn about modules in Python &#8211; how to create them, import modules in Python, how to execute a module as a script, standard Python modules, Python dir functions, and a lot more!<\/p>\n<p>Have a glance at the packages vs modules section to get an idea of Packages too and their advantages and disadvantages over each other!<\/p>\n<p><em><strong>No idea about Packages? Work it out here! &#8211; <a href=\"https:\/\/data-flair.training\/blogs\/python-packages\/\">Python Packages Guide<\/a><\/strong><\/em><\/p>\n<h4>2. Python Classes<\/h4>\n<p>It is nothing but a blueprint for objects. Explore more about how they work and access. Different attributes belonging to a <em><strong><a href=\"https:\/\/data-flair.training\/blogs\/python-class\/\">python class<\/a><\/strong><\/em> with its objects are discussed.<\/p>\n<p>As Python is an object-oriented language, it focuses on objects more than procedures.<\/p>\n<p>Though it is too much to take in, still have good hands-on these concepts as their understanding will help a lot later.<\/p>\n<h4>3. Python Methods<\/h4>\n<p>Much like functions, they are labels that you can call on an object; a piece of code to execute on that object.<\/p>\n<p>At the end of it, you will know how to define and make use of _init_ method, and also a self parameter.<\/p>\n<p><em><strong>Can\u2019t differentiate between Functions &amp; Methods? Refer here! &#8211; <a href=\"https:\/\/data-flair.training\/blogs\/python-method-vs-function\/\">Python Methods vs Functions<\/a><\/strong><\/em><\/p>\n<h4>4. Python Iterators<\/h4>\n<p>Create your own methods with <em><strong><a href=\"https:\/\/data-flair.training\/blogs\/python-iterator\/\">Python Iterators<\/a><\/strong><\/em>. Also, create a \u2018for loop\u2019 in iterators, infinite Python iterators, and the benefits of iterators with examples.<\/p>\n<p>After their complete understanding, they become handy and very interesting to use.<\/p>\n<h4>5. Python Decorators<\/h4>\n<p>What are they and why do we use them? All here! Also, along with this, cover decorators with Parameters and Pie syntax. Decorators are nothing but help add extra functionality to a function without modifying it.<\/p>\n<h4>6. Python Generators<\/h4>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/python-generator\/\"><em><strong> Generators<\/strong><\/em><\/a> are a kind of iterators that generate for us a sequence of values that we can iterate on.<\/p>\n<p><strong>Example:<\/strong> Use it to iterate on a for-loop in Python, but you can\u2019t index it.<\/p>\n<p>Before you start diving into the supreme and advanced level of the Learn Python mission, it\u2019s good that you ask yourself \u2018why you want to learn it?\u2019<\/p>\n<p>This is because Python has a \u2018sea\u2019 of applications, and each one of them is in the growing stage.<\/p>\n<p>Figuring out what actually you want to pursue will really help to find the end goal and set paths towards it.<\/p>\n<h3>Learn Python Advanced Level Topics<\/h3>\n<p>Ready to explore Python notes for advanced-level topics?
