A unique identifier can be calculated using the UUID (Universally Unique Identifier) Python module. To convert to a different Python type, use # built-in Python functions: str(), int(), float() count = int (result_value) print (count) print (type (count)) If creating output that is just an intermediate stage in a larger workflow, the output argument can be omitted to allow the tool to create a unique path and name for the output. Like before, we need to provide a start string, although this can be any length and does not necessarily need to be a substring that exists in the training text. I talk about generating UUIDs (universally unique IDs) into Python. Strings are among the most popular data types in Python. Below are the lists of a String array in Python: 1.
