Python批量重命名工作，但不能同時工作？

Question

當我從命令行運行程序時，我沒有得到任何錯誤，它似乎執行，但沒有任何反應！我已經準備好盯着代碼這麼久了。我只是想讓這個工作，所以我可以把它交給這個任務完成。

該程序應該運行如下。

沒有文件名都不會被添加到matching這裏：

if not os.path.isfile(path): 
    print "Warning: File type not expected" 
    continue 
    if os.path.isfile(path): 
    matching.append(name) 

也許你想擁有第二if在外部塊中，第一個沒有縮進if：

if not os.path.isfile(path): 
    print "Warning: File type not expected" 
    continue 
if os.path.isfile(path): 
    matching.append(name) 

或者更簡單：

if not os.path.isfile(path): 
    print "Warning: File type not expected" 
else: 
    matching.append(name)
