11. Use code below


Install package
```bash
pip install google-analytics-data
```

Python sample code:
```python
from google.analytics.data_v1beta import BetaAnalyticsDataClient
from google.analytics.data_v1beta.types import (
    DateRange,
    Dimension,
    Metric,
    RunReportRequest,
)
import os

os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "<your-key-file-name>.json"


def sample_run_report(property_id="YOUR-GA4-PROPERTY-ID"):

    client = BetaAnalyticsDataClient()

    request = RunReportRequest(
        property=f"properties/{property_id}",
        dimensions=[Dimension(name="city")],
        metrics=[Metric(name="activeUsers")],
        date_ranges=[DateRange(start_date="2020-03-31", end_date="today")],
    )
    response = client.run_report(request)

    print("Report result:")
    for row in response.rows:
        print(row.dimension_values[0].value, row.metric_values[0].value)


sample_run_report(property_id="<your-ga4-property-id>")
```
