递归 glob returns 没有文件

Question

for filename in glob.iglob(startPath, recursive=True):
    if(os.path.isfile(filename)):
        print('Encrypting> ' + filename)
        encrypt_file(key, filename)
        os.remove(filename)

当运行在 Python 3.7 中我没有收到任何错误但没有任何反应时，我正在使用它来加密用户注销时的敏感用户目录，所有其他部分我的程序工作。有人可以解释一下它有什么问题吗？

来自the doc for glob：

If recursive is true, the pattern “**” will match any files and zero or more directories and subdirectories. If the pattern is followed by an os.sep, only directories and subdirectories match.

所以，如果你想在这里使用glob，你需要包含这个模式：

for filename in glob.iglob(os.path.join(startPath, '**'), recursive=True):
     # ....

递归 glob returns 没有文件
