- New calculate_pi.py file implements Chudnovsky algorithm for high-precision pi calculation up to 10,000+ digits with progress tracking and file output - New pi_10000_digits.txt contains pre-calculated 10,000 digit pi result for demonstration purposes - Updated .gitignore with comprehensive Python development patterns including environment files, IDE configs, and build artifacts - Added command-line argument support and user confirmation for large calculations to prevent accidental resource exhaustion - Includes decimal precision handling and performance optimizations for mathematical computation This implementation provides a robust pi calculation tool with proper error handling, progress monitoring, and configurable output for high-precision mathematical applications. --- .gitignore | 72 +++++++++++++++++++++++++++- calculate_pi.py | 112 ++++++++++++++++++++++++++++++++++++++++++++ pi_10000_digits.txt | 1 + 3 files changed, 184 insertions(+), 1
