The Feature Set and Record Set data types allow interactive input of data. Feature Set allows the user of a script to interactively create features by clicking the map. Record Set allows the user to interactively create rows in a table grid. The symbology and schema (attributes and geometr...
It will be assigned internally in Python. You can also set default values to the instance attributes. The following code sets the default values of the constructor parameters. So, if the values are not provided when creating an object, the values will be assigned latter. Example: Setting ...
In other programming languages, we can define a specific set of values. To define infinity, we can use float("inf") to define a positive infinite number and for a negative infinite number, we use float("-inf"). Now, we will look at how it works in Python. Suppose we have a value...
