Question

根据我要创建文件夹的文件名的前3个字符，然后复制到相关文件中。

我有一个第一次运行的脚本，但是如果我多次运行它会出错我相信我需要先检查文件是否存在，但是我还没有能够让它工作。或者从os.list中过滤掉新创建的文件夹

非常感谢任何帮助：

srcpath = 'C:\\temp\\Test'
srcfiles = os.listdir(srcpath)
destpath = 'C:\\temp\\Test'

# extract the three letters from filenames
destdirs = list(set([filename[0:3] for filename in srcfiles]))


def create(destdirs, destpath):
    full_path = os.path.join(destpath, destdirs)
    if not os.path.exists(full_path):
        os.mkdir(full_path)
    return full_path


def copy(filename, dirpath):
    shutil.copy(os.path.join(srcpath, filename), dirpath)

# create destination directories and store their names along with full paths
targets = [
    (folder, create(folder, destpath)) for folder in destdirs
]

for destdirs, full_path in targets:
     for filename in srcfiles:
          if destdirs == filename[0:3]:
              copy(filename, full_path)

错误

Traceback (most recent call last):
  File "C:/Users/Desktop/copy_only.py", line 45, in <module>
    copy(filename, full_path)
  File "C:/Users/Desktop/copy_only.py", line 35, in copy
    shutil.copy(os.path.join(srcpath, filename), dirpath)
  File "C:\Python27\lib\shutil.py", line 119, in copy
    copyfile(src, dst)
  File "C:\Python27\lib\shutil.py", line 82, in copyfile
    with open(src, 'rb') as fsrc:
IOError: [Errno 13] Permission denied: 'C:\\temp\\Test\\F12'

您似乎正在尝试在C:\\temp\\Test\\F12中打开filename目录copy。否则，请检查您是否有权打开/阅读该文件。

根据文件名复制多重文件
