7.7.1.0 Edit Function
Use the Edit Function window to create user-defined functions using the Python programming language. The
Edit Function window lets you do the following:
• Create multi-line calculations and use them across test runs and analyses.
• Enter If statements, Loop statements, and other statements as supported in Python for more complex
calculations.
• Assign multiple variables to a function.
• Interact with other external sources.
• Validate statement syntax.
The validation section provides the result of the syntax check. The validation does not check for variable
scope or interaction with other functions and calculations. It is your responsibility to debug your functions and
ensure that they perform the calculations and results that you require.
You can enter the code in other editors and paste them into the Python Code work area.
