Oppiskele Challenge: Identify High Turnover Departments

In your HR data analysis journey, you have learned how to work with dictionaries to store and process structured information, such as employee or department data. Iterating through a dictionary allows you to access each key-value pair, making it possible to examine or manipulate the data based on specific criteria. Conditional logic, such as using an if statement, helps you filter out only the information that meets certain requirements. This skill is essential when you want to identify trends or outliers—like departments with unusually high turnover rates.

# Example: Identifying departments with turnover above a threshold

department_turnover = {
    "Sales": 0.15,
    "Engineering": 0.08,
    "HR": 0.12,
    "Marketing": 0.09
}

threshold = 0.10

for department, turnover in department_turnover.items():
    if turnover > threshold:
        print(f"{department} has high turnover: {turnover:.0%}")

When presenting the results, it is helpful to format your output so that high-turnover departments stand out clearly. You can print each qualifying department on a new line, including both the department name and its turnover rate as a percentage. Using string formatting, such as f"{value:.0%}", will display the turnover rate in an easy-to-read percentage format, making your HR reports more professional and actionable.
