Python scripting (with input table) 2.0
Summary
Applies a Python script to the current data node.
The script takes can read and write data from the following sources:
- The result table of the current data node,
- Result tables of othter data nodes,
- TIS Files,
- Parameters, and
- some metadata like the TIS version or the user name (only read access).
Python scripts can stored on the server's file system in two ways:
- as single files, where the file is linked in the operator settings and can be directly loaded and edited, or
- bundled in a Python ZIP file.
Either the single file or the __main__.py file in the ZIP file must contain one of the functions run, simple_main, create_table, and main (legacy), seePython scripting functions
The python version of the interpreter depends on the TIS version:
TIS release | Python version |
|---|---|
from v 6.6 | |
from v7.0 |
Modules from the Python Standard Library can be imported. Other modules can be imported if they have been included in the current deployment.
As a convention, 4-space indentation should be used instead of tabs, see PEP Style Guide. 
When pasting python scripts into the operator's editor, tab indentations are converted to 4-space indentations.
The operator looks for the functions one of the functions of the functions run, create_table, simple_main, and main to start execution.
The environment variable LANGUAGE (os.environ['LANGUAGE']) is set to the user's language. The project's language is ignored.
Settings
Parameter | Type | Opt. | Description | Example |
|---|---|---|---|---|
Select Python script file | System.Object | Path to TIS File containing the Python script | - | |
Evaluation timeout (ms) | System.Int | Maximum execution time. If exceeded, the operation terminates with an error. This value must be set between 1.000ms and 2.147.483.647ms. | 20000 | |
Python interpreter | CPython Pypy | Choice between two interpreters. Pypy can be faster in some use cases. | ||
Input data nodes | Opt. | List of data nodes whose result tables are provided via the run function's second argument. By convention, this argument is named intables or in_tables. They are lists of generators. Each generator iterates the result table of an input data node. The generator at index 0 refers to the current result table. The result tables of the input data nodes start at index 1. | ||
Output TIS Tables | Opt. | List of paths to TIS Tables that can be written via the run function's third argument. By convention, this argument is named outtables or out_tables. They are objects that can receive the output synchronously or asynchronously. Refer to the description of the run function for more information. | ||
Input files | Opt. | List of files that can be read in the script, see TIS File I/O in python scripting. | ||
Output file paths | Opt. | List of files that can be written by the script, see TIS File I/O in python scripting. |
