Python 获取名称错误NameError，函数未定义？

文件“/Users//Desktop/A5/driverModule.py”，第22行，在控制器中 tripInfo（） name错误：未定义名称“tripInfo”

好吧，我真的被卡住了，不明白为什么会出现这个错误。感谢您的帮助

这只是不鼓励导入的原因之一。从这里明确开始

from TripInfoModule import tripInfo, ...

如果那一行找不到tripInfo，那么你就更快地接近这个bug了

现在

tripInfo

在您称之为“Module2”的东西中定义

---

这个文件当然需要命名为“TripInfoModule”。确保没有可以加载的旧版本或

.pyc

文件，而不是您期望的文件

驱动程序模块中是否有

导入模块2

？是。这就是我不明白的。我正确导入了它，但它仍然给出了一个名称错误尝试此

打印（文件名\u.tripInfo（））

它返回什么？您正在使用的文件名是什么？我设计了3个模块。第一个模块获取用户输入，第二个模块进行一些计算并获取一些总数。最后一个模块是运行整个程序的驱动程序。我在第二个模块上遇到了一个问题，我发现了这个错误：ImportError:无法导入名称“tripInfo”@WonderphuL，是的，这告诉你Python在

TripInfoModule.py

中找不到

tripInfo

，所以这就是你需要解决的问题好吧，这就是我所困惑的。为什么它找不到？因为它不在那里。但你也知道这不是一个语法错误或其他问题。没有看到实际的文件，我无法告诉你更多。再次检查它是否正在加载您认为正确的文件。
