This package simplifies regular common actions for quick prototyping in a user friendly way

ccfx

ccfx is a comprehensive Python package designed to streamline file and data management, geospatial analysis, NetCDF file processing, database interactions, document generation, and multimedia handling for rapid prototyping and development workflows.

Features

1. File Management:

   • List, delete, move, copy, and count files/directories.
   • Monitor file count over time.
   • Save, load, and manage Python variables via pickle serialization.
   • Compress directories to .7z archives.
   • Read/write text files with encoding support.
   • Download files from URLs with resume and multi-connection support.

2. Geospatial Data Processing:

   • Read, write, clip (by extent/feature), resample, reproject, merge, and rasterize raster data (GeoTIFF, NetCDF).
   • Read, write, and clip vector data (Shapefile, GeoPackage).
   • Create grids of polygons based on shapefile boundaries.
   • Convert coordinates between Coordinate Reference Systems (CRS).
   • Extract raster values at specific coordinates.

   • Calculate sum and average maps from NetCDF data across multiple files.
   • Rename variables using CDO (if available).

4. Database Connectivity:

   • MS SQL Server: Connect, list databases/tables, read tables (including spatial data into GeoDataFrames), write DataFrames/GeoDataFrames to tables, drop tables.
   • SQLite: Connect, create/rename/drop tables, read tables (as dict, specific columns), insert data (rows, dicts, partial dicts), update values, dump tables to CSV.

5. Document & Spreadsheet Handling:

   • Excel: Create .xlsx files, add sheets, write data (including dates), set column widths, add scatter plot charts.
   • Word: Create .docx files, add headings, paragraphs (with alignment), list items, formatted text (bold/italic), images, page breaks, set margins.

6. Multimedia & Web:

   • Read and write MP3 metadata (ID3 tags), including album art.
   • Download videos/audio from YouTube using yt-dlp.

7. Data Analysis & Utilities:

   • Calculate timeseries statistics (NSE, KGE, PBIAS, LNSE, R2, RMSE, MAE, MSE, MAPE, alpha, beta) with resampling options.
   • Display dynamic progress bars.
   • Check system platform information.
   • Enable or disable warnings programmatically.
   • Set the working directory.

Installation

Install ccfx via pip:

pip install ccfx

Dependencies

ccfx relies on the following libraries:

• gdal: For geospatial raster and vector data manipulation.
• numpy: For array processing and numerical operations.
• pandas: For data manipulation and analysis.
• geopandas: Extends pandas to handle geospatial vector data.
• shapely: Provides geometric objects and operations.
• netCDF4: For working with NetCDF files.
• xlsxwriter: For creating and writing Excel .xlsx files.
• python-docx: Enables creation and manipulation of Word .docx documents.
• pyodbc: Enables connectivity to databases through ODBC (e.g., MS SQL Server).
• sqlalchemy: Provides SQL toolkit and ORM features for database access (used with MS SQL).
• py7zr: For creating .7z archives.
• mutagen: For reading and writing MP3 metadata (ID3 tags).
• requests: For downloading files via HTTP.
• tqdm: For displaying progress bars.
• yt-dlp: For downloading YouTube content.
• matplotlib (Optional, often used with geospatial/data analysis): For plotting.

These dependencies should be installed automatically when ccfx is installed via pip, but GDAL might require manual installation steps depending on your OS.
