Pythonプロジェクトでのデバッグの一貫性が向上

4月 10, 2026
PyCharm 2026.1は、デバッグ動作の一貫性と安定を向上するために、DAP (Debug Adapter Protocol)をデフォルトオプションとして導入

PyCharm by JetBrains is a comprehensive Integrated Development Environment (IDE) specifically designed for Python programming. It offers a range of features to enhance productivity, including code analysis for error detection, a visual debugger for troubleshooting, integrated unit testing for code verification, and support for version control systems to manage code changes. PyCharm also caters to web development using frameworks like Django, making it a powerful tool for both experienced developers and beginners in the Python world.

The PyCharm 2026.1 update introduces a new debugger option for Jupyter notebooks, allowing developers to use the Debug Adapter Protocol (DAP) as the default debugger. This brings greater consistency between notebook and standard Python debugging, helping reduce unexpected behaviour and improving overall stability. By aligning debugging experiences across different project types, it makes it easier to diagnose issues and maintain a smooth development process.

構造化スプレッドシートのテーブルでデータを整理

4月 10, 2026
構造化された整理、ソート、フィルタリング、一貫した計算、より明確な数式のために、スプレッドシート表でデータ管理を向上

Spreadsheet tables provide a structured way to organize and manage data by grouping related information into defined rows and columns with built in functionality. They enhance usability by enabling automatic sorting and filtering, consistent formula application through calculated columns, and clearer data interpretation with structured references and styling. Tables can also expand dynamically as new data is added, reducing manual updates and errors. Common use cases include managing financial records, analyzing sales performance, tracking inventory, and working with data bound to external sources, making them a powerful tool for both everyday tasks and advanced data analysis.

Several .NET spreadsheet controls offer table support including:

  • DevExpress Excel Spreadsheet API for .NET (part of DevExpress Office File API) allows you to manage spreadsheet tables with data binding and calculated columns.
  • EPPlus by EPPlus Software facilitates creation of spreadsheet tables with built in filtering, totals, and structured references to simplify data organization.
  • Infragistics Excel Framework lets you work with spreadsheet tables supporting dynamic ranges, consistent formulas, and enhanced formatting for efficient data handling.
  • Xceed Workbooks for .NET lets you create spreadsheet tables with structured data, enabling sorting, filtering, and consistent calculations across dynamic datasets.
