style=\"flex-basis:66.66%\">\n<p class=\"is-style-bstn-paragraph-documentation-body\">Before you can start programming with Python, there are a number of general programming fundamentals that are important to understand. Let\u2019s take a closer look at the basics.<\/p>\n\n\n\n<hr class=\"wp-block-bstn-blocks-section-divider bstn-blocks-section-divider bstn-blocks-section-divider--grey bstn-blocks-section-divider--32\"\/>\n\n\n\n<div class=\"wp-block-bstn-blocks-heading bstn-blocks-heading bstn-blocks-heading--h3 bstn-blocks-heading--mt-0 has-text-align-left\" id=\"programming-language-basics\"><h2 class=\"bstn-blocks-heading__heading-element\">Python Programming Language Basics<\/h2><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Programming languages tend to share some foundational concepts and general building blocks. By learning these concepts, we can gain a better understanding of any new programming language that we might come across in the future.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">With that being said, it is very important to have a solid understanding of the basics of programming languages before starting to write code. In most cases, only the process of writing code and executing it will change between individual languages. Let\u2019s dive into these building blocks and first deepen our understanding of syntax and semantics:<\/p>\n\n\n\n<div class=\"wp-block-bstn-blocks-heading bstn-blocks-heading bstn-blocks-heading--h4 has-text-align-left\"><h3 class=\"bstn-blocks-heading__heading-element\">Python Syntax<\/h3><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Syntax defines a set of rules and a combination of various symbols. Syntax is followed to write properly structured code that can be accepted by the language, before it is issued as instructions for the computer to run. Programming languages can vary in the syntax used, and code is written in a document with a particular file extension (e.g. for Python language code is written in a file with a &#8216;.py&#8217; extension). If the code written is not valid syntactically, the document will show \u201csyntax error\u201d. We\u2019ll explore Python syntax in the upcoming lessons.<\/p>\n\n\n\n<div class=\"wp-block-bstn-blocks-heading bstn-blocks-heading bstn-blocks-heading--h4 has-text-align-left\"><h3 class=\"bstn-blocks-heading__heading-element\">Python Semantics<\/h3><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">The semantics of a language are responsible for defining the meaning behind the syntax. In other words, it\u2019s not enough to write a sentence with the proper punctuation and grammar, and order of words if it doesn\u2019t mean anything. For example, the sentence \u201cThe desk ate the color blue.\u201d, is syntactically correct, but doesn\u2019t have any meaning. The same goes for programming. While code might be written with the right syntax in mind, the end result has to mean something.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">For our purposes, semantics describes a set of processes a computer will go through while executing the code in a particular language. This could be determining what output a program should produce for a given set of inputs or it could be just describing the process of how a code will be run on different platforms. Semantic analysis takes any code written and determines whether or not the code consists of valid strings. If not, the code would not be run and meaningful errors will be thrown to tell the programmer that the code contains errors.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">In this lesson, we will go through a quick introduction to&nbsp;<strong>Python<\/strong>&nbsp;as a programming language.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\"><strong>Note:<\/strong>&nbsp;We will be using&nbsp;<strong>Python 3<\/strong>&nbsp;for programming in Python.<\/p>\n\n\n\n<hr class=\"wp-block-bstn-blocks-section-divider bstn-blocks-section-divider bstn-blocks-section-divider--grey bstn-blocks-section-divider--32\"\/>\n\n\n\n<div class=\"wp-block-bstn-blocks-heading bstn-blocks-heading bstn-blocks-heading--h3 bstn-blocks-heading--mt-0 has-text-align-left\" id=\"how-to-write-python-code\"><h2 class=\"bstn-blocks-heading__heading-element\">How to Write Python Code<\/h2><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">While Python is one of the most beginner-friendly programming languages in use, it\u2019s a good idea to understand some core principles before getting started. Python programming courses, for example, have grown in popularity, as they can quickly get you up and running with the language.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">It\u2019s also a good idea to take advantage of the wealth of material available online. There are a number of PEP documents, for example, which can be invaluable for beginners. PEP stands for Python Enhancement Proposal, and these documents describe new features and aspects of Python, including documents, design, and style.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">PEP 8 is a readily-available document that aims to improve the readability and consistency of Python code \u2013 it also provides guidelines and best practices on how to write Python code.<\/p>\n\n\n\n<div class=\"wp-block-bstn-blocks-heading bstn-blocks-heading bstn-blocks-heading--h4 has-text-align-left\"><h3 class=\"bstn-blocks-heading__heading-element\">Python Expressions or Statements<\/h3><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">A Python expression or a statement is a line of code or building block that is syntactically correct and is supposed to carry out a certain action when executed.<\/p>\n\n\n\n<div class=\"wp-block-bstn-blocks-heading bstn-blocks-heading bstn-blocks-heading--h4 has-text-align-left\"><h3 class=\"bstn-blocks-heading__heading-element\">Indentation in Python<\/h3><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Indentation, also referred to as leading whitespace, is an important element of Python. The way that lines of code are indented in Python determines how statements are grouped together.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">\u200b\u200bPEP 8 includes two key indentation rules:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Make sure to use four consecutive spaces to indicate indentation.<\/li><li>Use spaces instead of tabs.<\/li><\/ul>\n\n\n\n<div class=\"wp-block-bstn-blocks-heading bstn-blocks-heading bstn-blocks-heading--h4 has-text-align-left\"><h3 class=\"bstn-blocks-heading__heading-element\">Comments in Python<\/h3><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Comments are essential building blocks of any programming language. Comments, unlike other programming features, are not executed and are used to explain your logic and assumptions in code where it might not be obvious to people reading the code. Comments are also used to add documentation to your code so that developers re-using your code know why and how to use that piece of code.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Comments should always answer the \u201cwhy?\u201d question. Why did you implement your code in that particular way or why was some assumption made? This helps developers or teammates reading your code easily understand the reasoning behind your implementation. Comments are also used to comment out lines of actual code that you don\u2019t want to execute.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Let\u2019s take a look at how Python as a programming language allows developers to use comments in their code.<\/p>\n\n\n\n<hr class=\"wp-block-bstn-blocks-section-divider bstn-blocks-section-divider bstn-blocks-section-divider--grey bstn-blocks-section-divider--32\"\/>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:25%\"><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-2 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-bstn-blocks-heading bstn-blocks-heading bstn-blocks-heading--h3 bstn-blocks-heading--mt-0 has-text-align-left\" id=\"single-line-comment-using-a-number-or-hashtag\"><h2 class=\"bstn-blocks-heading__heading-element\">Single-line comment using a hashtag sign #<\/h2><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Developers can add comments in Python by starting with a number or hashtag sign #.
