introduction:
python is a versatile and beginner-friendly programming language widely used for various applications, including web development, data analysis, artificial intelligence, and more. understanding how to output variables is fundamental to python programming. in this tutorial, we'll cover different methods to output variables in python with code examples.
method 1: using the print() function
the most common way to output variables in python is by using the print() function. this function takes one or more arguments and prints them to the standard output (usually the console).
example:
method 2: using f-strings (python 3.6+)

example:
method 4: concatenating strings
although less preferred compared to the previous methods, you can concatenate strings and variables using the + operator.
example:
conclusion:
outputting variables is an essential aspect of programming in python. by mastering the various methods demonstrated in this tutorial, you'll be equipped to display variables effectively in your python programs. whether you prefer the simplicity of print() function, the elegance of f-strings, or the flexibility of format() method, python offers multiple options to suit your programming style.
