python - 如何使用 python file.py 从命令行运行类？

Question

当我运行 python filename.py 时，它不会提示输入或打印输出。我必须运行什么命令才能运行类 Base1()？

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

您的程序必须在顶层包含一些语句(即不缩进)，这些语句将在您的程序在命令行上运行时执行。

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()
....
