Let’s use the | operator to append two sets into a single set in Python. This would return a new set that contains all of the elements frommyset1andmyset2, without any duplicates. # Create sets myset1 = {1,2,3,4,5,6} myset2 = {7,8,9,1,4} # Append using operator | my...
In the above example, we are opening the file named ‘img.bmp’ present at the location “C:/Documents/Python/”, But, here we are trying to open the binary file. Python Read From File In order to read a file in python, we must open the file in read mode. There are three ways ...

Note that the second argument "a" specified the mode to open the file with, in this case "Append" mode. This sets the writing position to the end of the file. If we had used the "w" (Write mode), then anything we write to the file will start at the very beginning and overwrite...
One way around this is to use the ArcGIS API for Python. If you are the data owner, or Administrator, you can truncate the feature service, and then append data. This is essentially an overwrite of the feature service. The below script will do this by specifying a local ...
Using both algorithms in a model, you can create complex ETL processes to migrate entire data sets from a data structure into another. Fortunately, you can find such a model after installing this plugin! Send the output of a Processing algorithm to an existing layer: ...

The advantage of this library is that the file format is very simple: it's valid Python code. The only requirement is that you only store primitive types, lists, sets, dicts and immutable types. Custom wrappers can be added by registeringTypeHandlers when creating aStore. SeeWeakEnumHandlerand...
