             'Rule': pieces[3]

    elif (pieces[0].startswith('')):
        result[count]['Incorrect'].append(pieces[1])

您可以在下面的代码中添加try以及跟踪哪行代码

using MvvmCross.iOS.Views.Presenters;

或者，如果您的所有行总是被拆分为相同长度的元素。您可以检查for line in open(file,'r').readlines(): try: pieces = line.split('\t') ... except IndexError as ie: print ie 如果长度不等于预期长度值，请使用len(pieces)忽略其余代码。
