Users can create and configure a Managed Metadata column to map to an existing term set or term, or they can create a new term set specifically for a Managed Metadata column. The arange () function in NumPy returns a one-dimensional NumPy array, which behaves like built-in container types in Python such as lists and dictionaries. Instead, an inline function with a reified type parameter is fine: So the way of defining a json column will be: Get back to the point, I also prefer the second approach, as it provides the flexibility to support arrays of arbitrary dimensions and it can make the code more simple. Include decimal places    Specify whether values include decimal places and the number of decimal places to store. For more on formulas and functions to use with the calculated field, see Examples of common formulas in SharePoint Lists. Calculated values are helpful when you want to display a specific date or time automatically but the date or time might vary depending on the item. Similarly, if the column stores the number of attendees for an event and you want to limit attendees to a specific number, you can enter the maximum number of attendees as the maximum value. The first is to continue to define a new array type each PostgreSQL data type (e.g., int[]would be implemented as IntArray, BaseTable.intArray, and IntArraySqlType).
