Your program must include some statements at the top level (i.e. not indented) that will be executed when your program is run on the command line.
您的程序必须包含一些顶级语句（即不缩进），当您的程序在命令行上运行时，这些语句将被执行。
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()
....

qwrrty 建议的内容会起作用，但我建议将它放在一个主要函数中，该函数在 python 中由
def main():
foo = Base1()
foo.base1()
if __name__ == "__main__":
main()
