我的程序在我的计算机上运行，但在CodeEval上不起作用

我现在正在研究CodeEval上的一个简单挑战。您需要逐行从文件中获取输入，每行包含由管道分隔的十六进制数字和二进制数字。目标是对左侧的所有十六进制数求和，对右侧的二进制数求和，并测试哪个总和更大。如果右侧（二进制边）大于或等于十六进制边，则打印"True"，如果不是，则打印"False"。示例行是"5e 7d 59 |1101100 10010101 1100111"，输出将为真，因为右侧大于左侧。我的代码在我的计算机上打印了正确的输出，但在 CodeEval 上，没有结果输出，我的分数为零。未列出任何错误。有没有我看不到的问题？
