8 Python’s Financial Limitations

8.1 Fragmented Ecosystem

Python’s financial tools are scattered across multiple packages:

# Python financial analysis is fragmented:
# - pandas (basic time series)
# - numpy (mathematical operations)
# - scipy (optimization)
# - statsmodels (basic econometrics)
# - No integrated financial platform

8.2 Limited Financial Focus

Python lacks specialized financial packages:

# Python lacks:
# - Comprehensive portfolio analysis
# - Advanced risk management
# - Sophisticated econometrics
# - Regulatory compliance tools
# - Financial reporting capabilities
