如何使用python file.py從命令行運行類？

Question

當我運行python filename.py時，它不會提示輸入或打印輸出。我必須運行什麼命令來運行Base1（）類？

class Base(TestCase): 

    def setUp(self): 
     #prompts for inpt 
     ...... 

class Base1(Base): 

    def base1(self): 
     print('.......') 
     return x 

    def base2(self): 
     output = Base1.base1(self) 
     print(output) 

Answer 1

您的程序必須包含一些在命令行運行程序時將執行的頂級語句（即不縮進）。

class Base(TestCase): 

    def setUp(self): 
     #prompts for inpt 
     ...... 

class Base1(Base): 

    def base1(self): 
     print('.......') 
     return x 

    def base2(self): 
     output = Base1.base1(self) 
     print(output) 

# These commands will be executed when "python filename.py" is run from a shell 
foo = Base1() 
foo.base1() 
.... 

Answer 2

什麼qwrrty建議將工作，但我會建議把它在這蟒蛇是由

def main(): 
    foo = Base1() 
    foo.base1() 

if __name__ == "__main__": 
    main()
