# Variables in Python # # Variables are easy to create in Python. And in this lesson you will easily learn how to create and apply them in your code. # So let's get started. A variable is a simple data type that has a name and a value. Variables are needed to store information in them. Let me explain with an example. Imagine a planet. In our case, the planet is a variable. The name of the variable is planet. # The planet has a name - Earth. This is the value of the variable. Thus, the variable (planet) stores information about the make of the car - Earth. # Here's what this variable looks like in Python: planet = "Earth" print (planet) # Let the variable now be the planets of the solar system (PSS) PSS = "Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune" print (PSS) ## Every time we create a variable and pass its name to the print function, the function prints the value of the variable to the screen, as in our example. By the way, if your variable name consists of more than one word, then you need to connect these words with an underscore. For example: my_car. However, I advise you to name your variables with only one word. This is a common and correct practice when working with variables. Well, now you know how programmers create and display variables in Python. # Not difficult at all, right? # Now let's practice a little. Below is some code that is missing something. You need to fix this so that the program can create a variable and display its value. # = " " # () variable = "0" print (variable) # Once you have completed this task, practice a little more. You can change the variable name and value. Add and display more new variables on the screen. # The more repetitions you perform, the better you will consolidate and hone your acquired skills! # RESULTS OF THE SECOND PART # # In the second part you did the following: # 1. Learned what variables are; # 2. Learned how to create variables in Python; # 3. We learned how to display variable values on the screen. # Great job! Let's move on to the third part: Numbers in Python. # I promise, no boring math! Let's get started.
