如何重命名PDF文件，从PDF文件中提取文本？
如何重命名PDF文件，从PDF文件中提取文本？
提问于 2014-07-21 06:58:36
我试图使用Python来重命名PDF文件，使用文件内容的一部分。情况就是这样。
PDF文件是商业发票，包含“商业发票”和“部门”字样。我想将文件重命名为“商业发票”和“部门"，如"353624人力资源”。
以下是我到目前为止所拥有的：
from StringIO import StringIO
import pyPdf
import os
# a function here
def getPDFContent(path):
content = ""
num_pages = 10
p = file(path, "rb")
pdf = pyPdf.PdfFileReader(p)
for i in range(0, num_pages):
content += pdf.getPage(i).extractText() + "\n"
content = " ".join(content.replace(u"\xa0", " ").strip().split())
return content
# name of the source PDF file
PDF_name = '222'
# picking texts from the PDF file
pdfContent = StringIO(getPDFContent("C:\\" + PDF_name + ".pdf").encode("ascii", "ignore"))
for line in pdfContent:
aaa = line.find(' Commercial Invoice ')
CIN = line[aaa + 28: aaa + 38]
bbb = line.find('Department')
Dpt = line [bbb+20 : bbb+26]
final_name = str(CIN + " " + Dpt)
print final_name
f = open("C:\\" + PDF_name + ".pdf")
f.close()
os.rename("C:\\" + PDF_name + ".pdf", "C:\\" + final_name + ".pdf")它直到打印出提取的文本‘print _name’，但在最后一部分重命名文件时，它会出现一个错误“WindowsError: error 32进程无法访问该文件，因为它正在被另一个进程使用”。
这里出了什么问题？文件似乎曾经被关闭过吗？

在def getPDFContent(path)中，在p = file(path, "rb")之后，当内容被复制时，您需要关闭该文件。
p.close()将它放在for循环之后，但放在函数中。

将C:\\添加到最后一行的PDF_name中。

这可以通过mouse_event完成，光标在下面的位置是代码：
