Python 在目录上移动文件时，shutil.move出错

我是Python新手，正在尝试编写一个脚本，根据文件类型将杂乱的文件夹分类到子文件夹中。由于某些原因，我在尝试运行脚本时，shutil.move出现错误

请原谅我的代码效率低下-我已经改变了很多尝试和调试！请查看附件中的我的代码和错误消息

import os
import shutil

filename =  os.getcwd()

print filename
print filename + '/Images'


#sort IMAGES
if os.path.exists(filename + '/Images'):
    print "Yes, Image folder exists"
else:
    print "No, it does not exists "
    print "Creating new directory for Images"
    os.makedirs(filename + '/Images')
filename1 = filename + '/Images'
#os.chdir(filename1)

for file in os.listdir(filename):
    if file.endswith(".JPG"):
        shutil.move(file,filename1)
    elif file.endswith(".png"):
        shutil.move(file,filename1)
    elif file.endswith(".gif"):
        shutil.move(file,filename1)

#sort Videos
if os.path.exists(filename + '/Videos'):
    print "Yes, Videos folder exists"
else:
    print "No, it does not exists "
    print "Creating new directory for Videos"
    os.makedirs(filename + '/Videos')
filename1 = filename + '/Videos'
#os.chdir(filename1)

for file in os.listdir(filename):
    if file.endswith(".mov"):
        shutil.move(file,filename1)
    elif file.endswith(".avi"):
        shutil.move(file,filename1)
    elif file.endswith(".mkv"):
        shutil.move(file,filename1)


#sort SONGS
if os.path.exists(filename + '/Music'):
    print "Yes, Music folder exists"
else:
    print "No, it doesnot exists "
    print "Creating new directory for Music"
    os.makedirs(filename + '/Music')
filename1 = filename + '/Music'
#os.chdir(filename1)

for file in os.listdir(filename):
    if file.endswith(".mp3"):
        shutil.move(file,filename1)
    elif file.endswith(".wav"):
        shutil.move(file,filename1)
    elif file.endswith(".wma"):
        shutil.move(file,filename1)


#sort DOCUMENTS
if os.path.exists(filename + '/Documents'):
    print "Yes, Documents folder exists"
else:
    print "No, it doesnot exists "
    print "Creating new directory for Documents"
    os.makedirs(filename + '/Documents')
filename1 = filename + '/Documents'
#os.chdir(filename1)

#check if it is neccessary to create new sub-directories for document types
contains_pdf = False
contains_doc = False
contains_ppt = False

for file in os.listdir(filename1):
    if file.endswith(".pdf"):
        contains_pdf = True
    if file.endswith(".docx"):
        contains_doc = True
    if file.endswith(".txt"):
        contains_doc = True
    if file.endswith(".ppt"):
        contains_ppt = True

#create subdirectories if does not exist
if os.path.exists(filename + '/Documents/PDF') == False and contains_pdf == True:
    os.makedirs(filename1 + '/PDF')
elif os.path.exists(filename + '/Documents/DOC') == False and contains_doc == True:
    os.makedirs(filename1 + '/DOC')
elif os.path.exists(filename + '/Documents/PPT') == False and contains_ppt == True:
    os.makedirs(filename1 + '/PPT')

filename2 = filename1
#move subtypes of documents in correct folders - THIS IS WHERE I GET MY ERROR!
for file in os.listdir(filename1):
    if file.endswith(".pdf"):
        filename2 = filename1 + '/PDF'
        shutil.move(file, filename2)
    if file.endswith(".docx"):
        shutil.move(file,filename1 + '/DOC')
    if file.endswith(".txt"):
        shutil.move(file,filename1 + '/DOC')
    if file.endswith(".ppt"):
        shutil.move(file,filename1 + '/PPT')
    filename2 = filename1

我想不出来。这就是我得到的错误

Traceback (most recent call last):
  File "organise.py", line 104, in <module>
    shutil.move(file,filename2)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 302, in move
    copy2(src, real_dst)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 130, in copy2
    copyfile(src, dst)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 82, in copyfile
    with open(src, 'rb') as fsrc:
IOError: [Errno 2] No such file or directory: '03_Anesthetic considerations in severe ankylosing.pdf'

回溯（最近一次呼叫最后一次）：
文件“Organize.py”，第104行，在
move（文件，文件名2）
文件“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py”，第302行，移动中
副本2（src、real_dst）
copy2中的文件“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py”，第130行
复制文件（src、dst）
copyfile中的第82行文件“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py”
开放式（src，'rb'）作为fsrc：
IOError:[Errno 2]没有这样的文件或目录：“03\u严重强直中的麻醉注意事项.pdf”

已修复

我正在传递一个需要传递路径的文件名。例如

for file in os.listdir(filename):
    if file.endswith(".pdf"):
        shutil.move(filename + file, filename1 + '/PDF/' + file)
    if file.endswith(".PDF"):
        shutil.move(filename + file, filename1 + '/PDF/' + file)
    if file.endswith(".docx"):
        shutil.move(filename + file, filename1 + '/DOC/' + file)
    if file.endswith(".txt"):
        shutil.move(filename + file, filename1 + '/DOC/' + file)
