How to Use Keywords

• Use them in the input field for formulas and expressions.
• Keywords used locally must be applied within specific environments. Refer to the Keywords usage column in the table above.
• The lambda syntax is straightforward: lambda arguments: expression. It functions identically to Python's lambda, but is restricted to use as the first parameter in map and filter functions. For detailed usage examples, refer to the relevant sections.
