Extract list of tools from a Python toolbox?

Question

Trying to dynamically get a list of tools and labels from a Python toolbox to drop into value table that makes it easy to call said tools. The closest I can come is this, but I don't see how I can "get at" the labels. ArcMap certainly can do this, why can't I? >>> arcpy.ImportToolbox(r"D:\Users\cprice ools\arcgis\PAPeakFlow\scripts\PolygonInfo.pyt") <module 'pinf' (built-in)> >>> dir(arcpy.pinf) ['AddFieldAndValue', 'CalcValuesToTable', 'IntersectArea', ... '__alias__', '__all__', '__builtins__', '__doc__', '__name__', ...]‍‍‍‍‍

If you can snag from namespace, then the inspect module is kind of useful. This demo just inspects itself, but code inside shows how you might factor it to provide other information. def num_41(func=None): """(num_41)...Documenting code using inspect :Requires: :-------- : import inspect # module :Source code for... : module level => inspect.getsourcelines(sys.modules[__name__])[0] : function level : as a list => inspect.getsourcelines(num_41)[0] : as a string => inspect.getsource(num_41) : file level => script = sys.argv[0] :Returns: a listing of the source code with line numbers :------- : """ def demo_def(): """dummy... : Demonstrates retrieving and documenting module and function info. : """ def sub(): """sub in dummy""" pass return None import inspect if func is None: func = demo_def script = sys.argv[0] # a useful way to get a file's name lines, line_num = inspect.getsourcelines(func) code = "".join(["{:4d} {}".format(idx, line) for idx, line in enumerate(lines)]) defs = [key for key, value in globals().items() if callable(value) and value.__module__ == __name__] args = [line_num, code, inspect.getcomments(func), inspect.isfunction(func), inspect.ismethod(func), inspect.getmoduleinfo(script), defs ] frmt = """ :---------------------------------------------------------------------- :Code for a function on line...{}... {} :Comments preceeding function {} :function?... {} ... or method? {} :Module info... {} : :Module functions... {} :---------------------------------------------------------------------- """ print(dedent(frmt).format(*args)) return None‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ And here is the output if you use num_41() to inspect itself Here is some output >>> num_41() :---------------------------------------------------------------------- :Code for a function on line...125... 0 def demo_def(): 1 """dummy... 2 : Demonstrates retrieving and documenting module and function info. 3 : 4 """ 5 def sub(): 6 """sub in dummy""" 7 pass 8 return None :Comments preceeding function None :function?... True ... or method? False :Module info... ModuleInfo(name='testing_script_03', suffix='.py', mode='r', module_type=1) : :Module functions... ['num_46', 'num_47', 'num_44', 'num_40', 'num_41', 'num_42', 'num_43', 'dummy', 'num_45'] :---------------------------------------------------------------------- ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Since the sample script is in a script (aka, module) there are a number of other functions in there. For example. I can pull in information from a particular module using >>> locals().keys() dict_keys(['dedent', ...snip ..., '__doc__', 'art', '__loader__', 'np', '__spec__', 'dummy', 'num_45']) >>> num_41(art) :---------------------------------------------------------------------- :Code for a function on line...0... 0 # -*- coding: UTF-8 -*- 1 """ 2 :Script: arr_tools.py ...... huge snip ......... 682 683 # ---------------------------------------------------------------------- 684 # __main__ .... code section 685 if __name__=="__main__": 686 """ """ 687 #print("Script... {}".format(script)) 688 a, b, c, d = _demo() ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ By using other options in the inspect module, you can extract a lot of information. I sometimes use this to get list of defs sometimes not revealed during the normal course of doing 'dir' or 'locals().keys()

I discovered arcpy.ListTools() in the help - this won't give me labels, but it will work for what I'm doing here arcpy.ImportToolbox(r'\Mac\Home\Documents\ArcGIS\Toolbox.tbx', "z") tools = arcpy.ListTools("*_z") for t in tools: print(t)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ gives me Model_z Model1_z FillPolygonHoles_z‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ The labels and descriptions seem out of reach so far from the limited of poking around that I've done, but this will do.
