What is output if the user enters -3?

Answers

Note that the correct output when the user enters -3 is -29. However, there must be some modifications to the code.

Why is this so?

Note that ff the user inputs -3, the software will produce an error message due to a syntax problem in the function declaration.

In the function definition, the multiplication operator (*) is substituted with the multiplication sign (), which is not a valid Python operator.

To correct the error, replace the multiplication sign () with the multiplication operator (*), as seen below....

   return 10 * x * y

n = int(input('Enter a number: '))

ans = trylt(n) + 1

HTML, CSS, and JavaScript are three of the most commonly used programming languages for creating web pages. HTML is used for creating the structure and content of a web page, while CSS is used for styling and formatting the content, and JavaScript is used for adding interactivity and dynamic features to the page. PHP and Python are two other programming languages that are often used for web development, with PHP being used for server-side scripting and Python being used for both server-side and client-side scripting. The choice of programming languages and synchronization depends on the specific needs and requirements of the project, as well as the preferences and skills of the developer.
