Leer Challenge: Generate Employee Report | Reporting and Insights for HR

As you move further into reporting and insights in HR, it is crucial to be comfortable iterating through lists of dictionaries and performing calculations based on their contents. In previous chapters, you have already worked with employee data structured as dictionaries, each containing fields such as name, department, and tenure. These skills allow you to efficiently count, summarize, and analyze HR information for reporting purposes.

When you need to generate an employee report, you often start by traversing the employee list. For each employee, you extract the department and tenure, and then use this information to compute totals, averages, and groupings. This process not only helps in summarizing the workforce but also in identifying trends and making data-driven decisions.

employees = [
    {"name": "Alice", "department": "HR", "tenure": 3},
    {"name": "Bob", "department": "Finance", "tenure": 5},
    {"name": "Charlie", "department": "HR", "tenure": 2},
    {"name": "Diana", "department": "IT", "tenure": 4},
    {"name": "Eve", "department": "Finance", "tenure": 1}
]

# Count employees per department
dept_counts = {}
for emp in employees:
    dept = emp["department"]
    if dept not in dept_counts:
        dept_counts[dept] = 0
    dept_counts[dept] += 1

print("Employee count per department:")
for dept, count in dept_counts.items():
    print(f"{dept}: {count}")

# Calculate average tenure
total_tenure = 0
for emp in employees:
    total_tenure += emp["tenure"]

average_tenure = total_tenure / len(employees)
print(f"Average tenure: {average_tenure:.2f} years")

When formatting a report for HR, clarity and organization are key. Use clear headings such as Employee Report or Departments to divide sections. Align numbers for readability and use consistent spacing. Consider breaking the report into logical parts: a title, a summary of total employees, a section listing departments with their respective employee counts, and a final section showing the average tenure. This structure ensures that your report is both informative and easy to read, making it valuable for stakeholders who rely on these insights for decision-making.
