Python tips #1 . If you ever wanted to modify a dictionary to do something if a key doesn't exist, the __missing__ magic method of a class has you covered. This will create an array if you access a missing key in the dictionary. #Python #Pythontips

class MyDict(dict): def __missing__(self, key): self[key] = [] return self[key] my_dict = MyDict() my_dict["values"].append(1) print(my_dict["values"]) # prints: [1]

ALT class MyDict(dict): def __missing__(self, key): self[key] = [] return self[key] my_dict = MyDict() my_dict["values"].append(1) print(my_dict["values"]) # prints: [1]

Python trick #1: . Python for loops have a little known ability. The else statement will be executed if no breakpoints are hit in the for loop. This is useful to remove the need for a variable . #Python #LittleKnownPython #PythonTricks

for i in [3, 2, 1]: if i == 0: break else: print("the break statement was not hit")

ALT for i in [3, 2, 1]: if i == 0: break else: print("the break statement was not hit")

Variable = a jar Value = a thing you can put in the jar Type = the type of thing you put in the jar Program = a recipe using stuff in all of your jars Put some beans in the jar so you can use them later in your chili recipe 😆 #programming #Coding
