callback

问题 I have a dictionary that has values sometimes as strings, and sometimes as a functions. For the values that are functions is there a way to execute the function without explicitly typing () when the key is accessed? Example: d = {1: "A", 2: "B", 3: fn_1} d[3]() # To run function I want: d = {1: "A", 2: "B", 3: magic(fn_1)} d[3] # To run function 回答1: Another possible solution, is to create a custom dictionary object that implements this behavior: >>> class CallableDict(dict): ... def _

问题 The below is the COMPLETE code. The output when I run this below simple kivy code on my laptop is "Hello from Kivy Success". While the output when I run using buildozer android debug deploy run from ubuntu to my mobile is "Hello from Kivy Error". I even added cacert.pem in my project folder, used ca_file=where(),verify=True. That too didn't help. Why does UrlRequest fail on my mobile? Please help me with a solution. from kivy.app import App from kivy.uix.floatlayout import FloatLayout from
