Try to return a value of a variable in the workspace.

ws.findTry(varName[, missing]) -> object

If the variable has no values, the operation will return
the value specified by "missing", which defaults to the value
"None".

Note that (unlike fetchTry) findTry does not remove the value.
The value remains in the variable.

Arguments:

varName -- Name of the variable to use.

missing -- Value to return if the variable has no values.  The
default is None.
