        self.tc_pass('OLV Engine Host installed')
        """

    def main():
        lago()

    main()

但是，输出中显示它不存在

Traceback (most recent call last):
  File "C:/Users/rafranci/Downloads/ovirt_st_setup.py", line 20, in <module>
    class InstallTest():
  File "C:/Users/rafranci/Downloads/ovirt_st_setup.py", line 65, in InstallTest
    main()
  File "C:/Users/rafranci/Downloads/ovirt_st_setup.py", line 63, in main
    lago()
NameError: name 'lago' is not defined

据我所知，这没有任何理由 - 想法？

检查代码的变化:
