The program showcases the definition of functions, the concept of function composition, and the process of calling functions to achieve a specific output. Understanding how to define and use functions is fundamental to modular and efficient code in Python.<\/p>\n<h2>Prerequisites<\/h2>\n<ul>\n<li>Basic understanding of functions in Python.<\/li>\n<li>Familiarity with function definition and function calling concepts in Python.<\/li>\n<\/ul>\n<h3>Topic Explanation<\/h3>\n<p><strong>The program consists of two functions:<\/strong> display(f) and msg(). The msg() function returns the string &#8220;Free Course,&#8221; and the display(f) function takes a parameter f and concatenates it with &#8220;Data Flair.&#8221; The program then calls the msg() function and passes its result as an argument to the display(f) function. The final result is stored in the variable x and printed.<\/p>\n<p>The program not only introduces the functions display() and msg() but also sheds light on the importance of function composition and the sequential execution of these functions to achieve a specific output. By showcasing the step-by-step process of calling msg() first to obtain &#8220;Free Course&#8221; and then passing this result as an argument to display(f), readers gain valuable insights into the flow of function execution and the concept of function chaining. This deeper understanding of function composition can be a crucial building block for more complex Python programming tasks.<\/p>\n<h4>Code:<\/h4>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\"># Function definition: display takes a parameter 'f' and concatenates it with the string \"Data Flair\"\r\ndef display(f):\r\n    return \"Data Flair \" + f\r\n\r\n# Function definition: msg returns the string \"Free Course\"\r\ndef msg():\r\n    return \"Free Course\"\r\n\r\n# Calling the display function with the result of the msg function as its argument\r\n# The result is displayed by the variable 'x'\r\nx = display(msg())\r\n\r\n# Printing the value of 'x'\r\nprint(x)<\/pre>\n<div class=\"df-code-out\"><strong>Output:<\/strong><br \/>\nData Flair Free Course<\/div>\n<h4>Code Explanation:<\/h4>\n<p><strong>1.<\/strong> Defines a function called display() that takes one parameter f<\/p>\n<ul>\n<li>The function concatenates f with the string &#8220;Data Flair&#8221;<\/li>\n<li>It returns the concatenated string<\/li>\n<\/ul>\n<p><strong>2.<\/strong> Defines a function called msg()<br \/>\nThis function returns the string &#8220;Free Course&#8221;<br \/>\n<strong>3.<\/strong> Calls the display() function, passing the result of calling msg() as the argument<\/p>\n<ul>\n<li>msg() is called first, which returns &#8220;Free Course&#8221;<\/li>\n<li>This string is passed as parameter f to display()<\/li>\n<\/ul>\n<p><strong>4.<\/strong> The result of calling display(msg()) is assigned to the variable x<\/p>\n<ul>\n<li>So x now contains the string &#8220;Data Flair Free Course&#8221;<\/li>\n<\/ul>\n<p><strong>5.<\/strong> Prints out the value stored in x<\/p>\n<ul>\n<li>This prints &#8220;Data Flair Free Course&#8221;<\/li>\n<\/ul>\n<h3>Summary<\/h3>\n<p>In summary, this Python program serves as an instructive guide, illuminating core principles of function definition, composition, and invocation. It provides insights into defining functions systematically, fostering modular code development. Function composition is elegantly exemplified, showcasing how functions combine for versatility. The tutorial underscores function invocation, revealing Python&#8217;s dynamic nature. This concise yet comprehensive resource equips readers with essential skills for creating modular, efficient, and maintainable Python code, making it invaluable for both beginners and experienced developers seeking proficiency in Python programming.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this article, we will explore a Python program that involves the creation and use of functions.
