我正在比较 wav 文件，这个脚本运行良好，直到我切换到 LMDE Betsy。给我错误的功能是：
def already_valid (arg_wav):
for w in wavs:
size_arg = getsize(arg_wav.src_path)
size_w = getsize(w.src_path)
if 0 < size_w == size_arg and w.src_path != arg_wav.src_path:
print arg_wav.src_path, "::", w.src_path
if audiodiff.audio_equal(arg_wav.src_path, w.src_path):
return True
return False
我的第一个想法是它试图两次打开同一个文件，但w.src_path != arg_wav.src_path应该考虑到这一点。我得到这个输出：
从我的功能：
/home/will/Desktop/soundfiles/TITAN Recordings/6648/hold1_por.wav :: /home/will/Desktop/soundfiles/TITAN Recordings/6677/hold1_por.wav
追溯：

奇怪的是它昨天在 Linux Mint 17.1和Windows 7 上运行。这是我不知道的一些奇怪的 Debian 约定吗？是的，我仔细检查了两个文件都存在于所描述的路径中。
