code. Let\u2019s take a closer look.<\/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=\"what-are-conditional-statements-in-python\"><h2 class=\"bstn-blocks-heading__heading-element\">What Are Conditional Statements in Python?<\/h2><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Let\u2019s deep dive further into programming with Python by learning about conditional statements. Usually, code is read by a Python interpreter line-by-line in the order it is written. But, what if we want to execute a certain part of code only when it meets certain criteria?<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Conditional statements are very useful in programming as they allow us to switch the execution of code based on logical decisions and criteria. They allow you to run a block of code only when certain conditions are met.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">Let\u2019s look into how to use conditional statements in your code. We will also use the reserved keywords&nbsp;<code>and<\/code>,&nbsp;<code>not<\/code>, &amp;&nbsp;<code>or<\/code>&nbsp;that we learned about in the previous lesson.<\/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=\"introduction-to-python-if-else-statements\"><h2 class=\"bstn-blocks-heading__heading-element\">Introduction to Python If Else Statements<\/h2><\/div>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\"><code>if...elif...else<\/code>&nbsp;statements are a very useful way to introduce conditional statements in your code. It allows you to execute a block of code only when certain conditions are met, or else skip to the next section of the code. Let\u2019s take a quick look at the basic syntax of&nbsp;<code>if...elif...else<\/code>&nbsp;statements in Python.<\/p>\n\n\n\n<p class=\"is-style-bstn-paragraph-documentation-body\">There are two ways in which you can use&nbsp;<code>if....elif...else<\/code>&nbsp;statements. The first is when you only have one condition to check to execute a block of code, you can use the&nbsp;<code>if...else<\/code>&nbsp;statement. In this scenario, the syntax looks as follows:<\/p>\n\n\n\n<div class=\"wp-block-bstn-blocks-code-snippet bstn-blocks-code-snippet\" data-code-snippet=\"true\"><div class=\"bstn-blocks-code-snippet__title-bar\"><span class=\"bstn-blocks-code-snippet__title\">Code Example<\/span><button class=\"bstn-blocks-code-snippet__copy-trigger\" aria-label=\"Copy code to clipboard\" data-copy-to-clipboard=\"true\"><svg viewbox=\"0 0 12 13\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"bstn-blocks-code-snippet__copy-trigger-icon\"><path d=\"M10.875.5h-7.5c-.633 0-1.125.516-1.125 1.125V2.75H1.125C.492 2.75 0 3.266 0 3.875v7.5A1.11 1.11 0 001.125 12.5h7.5c.61 0 1.125-.492 1.125-1.125V10.25h1.125c.61 0 1.125-.492 1.125-1.125v-7.5A1.14 1.14 0 0010.875.5zm-2.39 10.875h-7.22c-.093 0-.14-.047-.14-.14v-7.22c0-.07.047-.14.14-.14h.985v5.25a1.11 1.11 0 001.125 1.125h5.25v.984c0 .094-.07.141-.14.141zm2.25-2.25h-7.22c-.093 0-.14-.047-.14-.14v-7.22c0-.07.047-.14.14-.14h7.22c.07 0 .14.07.14.14v7.22c0 .093-.07.14-.14.14z\" fill=\"currentColor\"><\/path><\/svg><span data-copy-to-clipboard-text=\"true\">Copy<\/span><\/button><\/div><pre class=\"bstn-blocks-code-snippet__code-snippet-area match-braces line-numbers language-python\" data-language=\"python\" aria-readonly=\"true\"><code>if condition:\n    Block of code to execute when this condition is True.
