创建新目录和移动文件时出现错误

Question

我有一个脚本，在创建一堆文件之后，将创建一个新目录，然后将这些文件移到新目录中。一开始还可以，但突然间我遇到了一个错误，我不知道为什么会这样。 编辑：我添加了我以前的代码（都在同一个模块中）给那些想知道的人。在

我的代码：

import os
import shutil
mydir = os.getcwd()

def edit_and_rename_files():
    f = filelist() # an earlier script that just makes a list of files I care about
    for item in f:
        with open(item, "r+") as id_file:
            for line in id_file:
               does something
              return my_dict # just a dict with ids I want to rename

        with open(item, "r+") as infile:
            content = infile.readlines()
            new_content = []
            for line in content: # going to copy and rewrite some lines
                new_line = line
                for original_id, new_id in my_dict.items():
                    new_line = new_line.replace(original_id, new_id + "\n")
                new_content.append(new_line)

       with open(item+"_renamed.fa", "w") as outfile:
           for line in new_content:
               outfile.write(line)

edit_and_rename_files()                 


def move_files():
    renamed_dir = mydir + "\\renamed"
    if not os.path.exists(renamed_dir):
        os.mkdir(renamed_dir)
    else:
        print "This directory already exists. Will move the files into this directory anyways."

   for root, dirs, files in os.walk(mydir):
        for fname in files:
            if fname.endswith("_renamed.fa"):
                shutil.move(fname, renamed_dir)

move_files()

这个脚本执行，文件被创建，实际上移动很好（当我打开文件时没有错误），但是我仍然得到一个错误，它让我很恼火。在
