What tools do you use for generating data structures or reports?.

In practice, for generating data structures and reports in Python, I often use the following tools:

• Pandas — for processing and structuring tabular data, convenient for preparing data for reports.
• Jinja2 — a templating engine for generating reports in HTML format or text files.
• ReportLab — for creating PDF reports with precise element positioning.
• OpenPyXL or XlsxWriter — for generating Excel files with reports.

Example of generating a simple report in Excel using pandas and OpenPyXL:

import pandas as pd

data = {'Name': ['Ivan', 'Maria'], 'Age': [28, 34]}
df = pd.DataFrame(data)
df.to_excel('report.xlsx', index=False)

This approach allows for quickly creating structured reports for further analysis or presentation.
