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.

# The union of two lists
The **union** operation combines two sets, skipping the matching values of both sets while populating the resultant set.



Unlike sets, lists may contain duplicate values. For example:


* The union of $[2,5,8,9,30,45]$ and $[4,5,6,7,8,9,10]$ should be $[2,4,5,8,9,10,30,45]$.

* The union of $[2,5,5,8,9,30,45]$ and $[4,5,6,7,8,9,10]$ should be $[2,4,5,5,8,9,10,30,45]$.

* The union of $[2,5,5,8,9,30,45]$ and $[4,5,5,6,7,8,9,10]$ should be $[2,4,5,5,8,9,10,30,45]$.

The following program unites two lists, assuming that the operand lists are sorted. This operation may result in duplicate values.
