以下代码均采用Python 3.5.2编写。 建立一个名为HelloWorld.py的文件，当然名字无所谓，只要不是文字提及的其它文件名字即可，读懂以下代码方可轻松入门Python：
#Class class Bird(object): feather= True reproduction="egg" def chirp(self, sound): print(sound) def set_color(self,color): self.color=color return color summer = Bird() summer.chirp("jijijiji") print(summer.feather) print(summer.set_color("yellow")) #Magic Method class Bird2(object): def __init__(self, sound): self.sound=sound def chirp(self): print(self.sound) summer = Bird2("jiji") summer.chirp() #Inheritance class Chicken(Bird): how_to_move = "walk" edible=True class Swan(Bird2): how_to_move = "swim" edible=False def chirp(self): super().chirp() print("jijijiji") summer = Chicken() summer.chirp("ji") bird=Bird2("ji") bird.chirp() summer = Swan("ji") summer.chirp() #class list i = [1, 2, 3, 4, 9.0, "Good", -1, True, False, "Bye"] print(i.count(4)) print(i.index(3)) i.append(6) print(i) i.reverse() print(i) i.pop() print(i) i.remove(2) print(i) i.insert(0,9) print(i) i.clear() print(i) #iter example_iter=iter([1,2,3,4]) print(type(example_iter)) print(example_iter.__next__()) print(example_iter.__next__()) for i in example_iter: print(i, "example_iter in for") #generator def gen(): a=100 yield a a=a*8 yield a yield 1000 print(type(gen())) for i in gen(): print(i) #class Module import time print(dir(time)) from time import sleep sleep(1) print("Wake Up") from time import * sleep(1) print("Wake Up 2") time.sleep(1) print("Wake Up 3")为了方便起见，可以将未读到的章节注释掉。
