Four. attempt to get the __name__ characteristic, assuming obj is a module. there is a chance obj has a __name__ and no __module__ yet isn't a module. we are going to forget about this probability (see the part Code isn't whole later during this chapter). five. If obj doesn't have a __name__, hand over, and go back None. 6. If we do locate what we expect is a module identify, go back real if it starts with the string "pymel" and fake if not. we do not have to try out this functionality at once. we will be able to simply upload one other try to our current try out functionality. the hot assessments are in highlighted within the following code. def testpyto_helpstr(): def dotest(obj, ideal): consequence = pyto_helpstr(obj) assert end result == excellent, '%s ! = %s' % (result, perfect) dotest('maya rocks', 'search. html? q=maya+rocks') dotest(pmc. nodetypes, 'generated/pymel. middle. nodetypes. html' '#module-pymel. middle. nodetypes') dotest(pmc. nodetypes. Joint, 'generated/classes/pymel. middle. nodetypes/' 'pymel. middle. nodetypes. Joint. html' '#pymel. middle. nodetypes. Joint') dotest(pmc. nodetypes. Joint(), 'generated/classes/pymel. center. nodetypes/' 'pymel. middle. nodetypes. Joint. html' '#pymel. middle. nodetypes. Joint') dotest(pmc. nodetypes. Joint(). getTranslation, 'generated/classes/pymel. center. nodetypes/' 'pymel. center. nodetypes. Joint. html' '#pymel. middle. nodetypes. Joint. getTranslation') dotest(pmc. joint, 'generated/functions/pymel. center. animation/' 'pymel. center. animation. joint. html' '#pymel. center. animation. joint') dotest(object(), None) dotest(10, None) dotest([], None) dotest(sys, None) Reload minspect and run the try out functionality. the 1st new try out may still fail. Let's move in and edit our code in minspect. py so as to add aid for non-PyMEL gadgets. The alterations are highlighted. def pyto_helpstr(obj): if isinstance(obj, basestring): go back 'search. html? q=%s' % (obj. replace(' ', '+')) if now not ispymel(obj): go back None if isinstance(obj, kinds. ModuleType): go back ('generated/%(module)s. html#module-%(module)s' % dict(module=obj. __name__)) if isinstance(obj, kinds. MethodType): go back ('generated/classes/%(module)s/' '%(module)s. %(typename)s. html' '#%(module)s. %(typename)s. %(methname)s' % dict( module=obj. __module__, typename=obj. im_class. __name__, methname=obj. __name__)) if isinstance(obj, varieties. FunctionType): go back ('generated/functions/%(module)s/' '%(module)s. %(funcname)s. html' '#%(module)s. %(funcname)s' % dict( module=obj. __module__, funcname=obj. __name__)) if no longer isinstance(obj, type): obj = type(obj) go back ('generated/classes/%(module)s/' '%(module)s. %(typename)s. html' '#%(module)s. %(typename)s' % dict( module=obj. __module__, typename=obj. __name__)) it will be significant that the ispymel payment comes early so we do not attempt to generate PyMEL URLs for non-PyMEL items. we have a comparatively entire functionality we will be able to be happy with. Reload and run your checks to make sure every thing now passes. Designing with EAFP as opposed to LBYL In ispymel, we used a try/except assertion instead of fee if an item has an characteristic. This development is named more straightforward to invite for Forgiveness than Permission (EAFP). by contrast, checking issues prior to time is termed glance prior to You bounce (LBYL).
