该程序确实会迭代，但只会迭代到某一行代码。然后它开始将开始和停止变量读取为 7 和 9 之类的东西？！？！我不明白这里有什么问题。更奇怪的是，它从 7,9 跳到 48, 51（开始、停止值）。这是代码的主要部分：http: //pastebin.com/S0FZ3Jk7 ，这是我使用的数据：http: //pastebin.com/rchNJGBq

我不打算审查你的整个程序来解决这个问题，但作为你的回溯的一部分，我确实一目了然：

def update_qualifier(data):
    tqual = Qualifier()
    tqual.name = data[0]
    tqual.rp = data[1]
    tqual.hs = data[2]
    tqual.num_of_matches = tdata[3]
    return tqual

你的意思是在tdata[3]这里引用一个全局变量，而不是你的 localdata吗？

您的just_qualifiers方法返回一个列表或 -1（哎呀！为什么不是一个空列表？）。

您调用它一次，获取值 -1，将其分配给 tdata，然后立即调用just_qualifiersAGAIN（为什么？），如下所示：if not just_qualifiers(tdata) == -1:这等同于if not just_qualifiers(-1) == -1:导致函数内部观察到的错误 - 它正在尝试执行for line in -1:

我强烈建议您重写该函数，以便在没有限定符的情况下返回一个空列表。同上任何其他类似的功能。遍历空列表是非常安全的，即for line in data:如果为空，则不会优雅地执行任何操作data。如果您需要检查它是否为空，您可以简单地做if data:或if not data:根据需要。
