我的脚本在特定目录中搜索所有pdf文件,然后从pdf中提取ID,并在文件内整理pdf。例如,我有:
C:\Users\user\Downloads\aa\1.pdf, with id = 3,
C:\Users\user\Downloads\aa\2.pdf, with id = 5,
C:\Users\user\Downloads\aa\3.pdf, with id = 10
我想这样组织他们:
C:\Users\user\Downloads\aa\3\1.pdf
C:\Users\user\Downloads\aa\5\2.pdf
C:\Users\user\Downloads\aa\10\3.pdf
以下脚本可以完成这项工作,但是我认为仅对于最后一个文件,它会输出以下错误:
回溯(最近通话最近): 文件“ C:\ Users \ user \ Downloads \ aa \ project.py”,第74行,在 os.rename(来源,目标) PermissionError:[WinError 32]该进程无法访问文件,因为该文件正在被另一个进程使用:'C:\ Users \ user \ Downloads \ aa \ 3.pdf'->'C:\ Users \ user \ Downloads \ aa \ 10 \ 3.pdf'

答案 0 :(得分:0)
首先,我认为由于复制和过去的某些缩进被打乱了,实际上其中一部分应该是:
for i in files:
pdfFileObj = open(files[c],'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
num_pages = pdfReader.numPages
count = 0
text = ""
while count < num_pages:
pageObj = pdfReader.getPage(count)
count +=1
text += pageObj.extractText()
keywords = []
keywords = re.findall(r'[0-9]\w+', text);
gesi_id.append(keywords[0])
key = str(gesi_id[c])
value = files[c]
dic[key] = value
c=c+1
要解决该问题,您只需要通过在当前位置添加pdfFileObj.close()
来关闭当前使用的文件即可。
for i in files:
pdfFileObj = open(files[c],'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
num_pages = pdfReader.numPages
count = 0
text = ""
while count < num_pages:
pageObj = pdfReader.getPage(count)
count +=1
text += pageObj.extractText()
keywords = []
keywords = re.findall(r'[0-9]\w+', text);
gesi_id.append(keywords[0])
key = str(gesi_id[c])
value = files[c]
dic[key] = value
c=c+1
pdfFileObj.close()
