Package-level functions ¶
The following top-level attribute functions are designed to be used in parameters with Python expressions. You can use pdg.workItem() to get the current work item object in a Python expression, and use it to access other methods and properties from the pdg.WorkItem class. For example, the Python expressions pdg.workItem().floatAttribValue("foo", 1) and pdg.WorkItem()["foo"][1] are equivalent to the HScript expression @foo.1.
input(index=None, tag=None, localize=False)
→ list
or str
Returns the input files of the current work item.
This is intended to be used in Python expressions. The HScript expression equivalent is @pdg_input.
The return type depends on the index keyword argument. If index=None, the function returns a list of input files. Otherwise, it returns the indexth input file path.
isEvaluating()
→ bool
Returns True if the calling thread is evaluating a PDG work item, else returns False.
kwargs(key=None)
→ obj
or dict
This is intended to be used in Python expressions. Looks up a local variable from the expression evaluation context.
The return type depends on the key keyword argument. If key=None, the function returns all local variables as a dict. Otherwise, it returns the value for the given key.
workItem()
→ pdg.WorkItem
This is intended to be used in Python expressions. Returns the current work item object.
