Variables and Numbers

>>> ## Concept Variables in Python are used to store information that you want to reuse later in your program. Think of a variable as a container that holds data, like a labeled jar. You can store numbers in variables to make calculations easier and to make your code more readable. ### Creating Variables To create a variable, assign a value to it using the `=` sign. ```python number = 10 ``` Here, we created a variable named `number`, and it holds the value `10`. ### Using Variables in Calculations Variables can be used to perform mathematical operations. ```python x = 5 y = 3 result = x + y print(result) # Output: 8 ``` In this example, `x` holds the value `5` and `y` holds `3`. We add them together and store the result in a new variable called `result`. ### Updating Variable Values You can update the values stored in variables. ```python score = 20 score = score + 5 print(score) # Output: 25 ``` Initially, `score` is `20`, and we update it by adding `5` to assign the new value `25`. ## Practice Now it’s your turn to create and use a variable. Follow these steps to complete the task: 1. **Create a variable** called `score`. 2. **Assign it** a value of `100`. 3. **Print** the value of `score`. Here is the basic format you should use in your code: ```python score = 100 print(score) ``` Modify the starter code to include the lines above. Once done, test your code to ensure it prints `100`, as expected in the test case. This verifies that you have successfully stored and printed the number using a variable.
