文件应该映射出文件所在的文件夹及其所有子目录。出于某种原因,当代码运行其20150迭代时 folder=下一个(os.步行(操作系统getcwd()+'/'+文件夹列表[0]))[1] 终止代码并且不抛出任何错误。我不知所措。我用sudo运行代码。你知道吗
我可以在代码中看到两件事:
在同一次迭代中,您在生成器上调用了
.next()
两次。我不认为这是您想要做的,您的迭代将解析两个不同的os.walk
输出。将os.walk(os.getcwd()).next()
的输出保存在var中并使用它。仅当当前级别中没有文件夹时才处理文件列表,因为您使用
elif
来执行list_of_files
。您应该使用if
,因为您无论如何都要处理它。另外,请记住迭代器的结尾会抛出一个
StopIteration
异常,所以很可能就是这样。你需要处理这个异常。你知道吗相关问题 更多 >
