9. Data Visualization Tools: Tableau and Power BI

Learning Objectives Explain what data visualization tools like Tableau and Power BI are used for. Identify `if/elif/else` statements in Python code. Use a `for` loop to process each item in a list. Write a simple Python script that uses a `for` loop and an `if` statement to filter a list of numbers. Use an `if/else` statement inside a loop to categorize data into two groups. Explain why organizing data with Python makes it easier to create charts in other tools. Ever wonder how your favorite game shows a leaderboard chart with the top players? 📊 Before a cool chart can be made, the data needs to be sorted and organized first! In this lesson, we'll learn how to use Python's special 'control structure' commands, like `if` statements and `for` loops, to ge...

TermDefinitionExample Data Visualization ToolA computer program like Tableau or Power BI that turns lists of data (like numbers and words) into cool pictures like charts, graphs, and maps.Using Power BI to turn a list of student birthdays into a bar chart showing how many birthdays are in each month. Control StructureA command in Python that controls the 'flow' or order of the code. It tells the computer which lines to run, when to run them, and how many times.A `for` loop is a control structure that tells the computer to repeat a set of instructions for every item in a list. Conditional Statement (if/else)A type of control structure that makes a choice. It checks if a condition is true and runs different code depending on the answer.`if score > 90: print('You got an A!&...

The `for` Loop Pattern for item_variable in list_name: # Code to repeat for each item Use this when you want to do the same action for every single item in a list. The loop will take each item from `list_name`, one by one, put it into `item_variable`, and run the indented code. The `if/else` Decision Pattern if condition: # Code to run if condition is true else: # Code to run if condition is false Use this when your program needs to make a choice between two options. The computer checks the `condition`. If it's true, it runs the code under `if`. If it's false, it runs the code under `else`. The Filtering Pattern for item in list_name: if condition_about_item: # Do something with the item This is a powerful combination. Use the `for`...
