The tools that help create a document, a movie, or a game are all programs. This course uses Python as its programming language. Python programmers are in high demand. The programs you’ll learn in this course are specially designed for learners with no programming background. 

You’ll start with simple math, real-world problem-solving, and writing solutions as steps in a simple language. Next, you’ll learn decision-based solutions demonstrated via flowcharts and explained with execution sheets. Finally, you’ll learn to translate your solutions into Python programs using variables, conditional statements, loops, strings, lists, and built-in functions. You’ll also learn to create your own functions in Python.

Plenty of practice programs with the facility of editing and running them in an embedded way will add to your confidence. After completing this course, you can start as a Python developer. Python is used in business, web, healthcare, education, data science, scraping, embedded systems, and games.

Let’s say we have two integers input by the user in the variables `p` and `q`. Which of the following conditional expressions shows that `p` is a _multiple of_ `q`? 

(A number is a multiple of another number if its division gives an integer result.)



Let’s say we have two integers input by the user in the variables <code>p</code> and <code>q</code>. Which of the following conditional expressions shows that <code>p</code> is a multiple of <code>q</code>?
(A number is a multiple of another number if its division gives an integer result.)

**(Select all that apply.)** Let’s say we have an integer input by the user in the variable `num`. Which of the following conditional expressions show whether the integer is an odd number?

The rule is that a natural number not divisible by 2 is an _odd_ number.

(Select all that apply.) Let’s say we have an integer input by the user in the variable <code>num</code>. Which of the following conditional expressions show whether the integer is an odd number?

The rule is that a number is prime if it is divisible only by itself and by 
$1$.
