How do I overwrite a file currently being read by Python
- by Brian
Hi guys,
I am not too sure the best way to word this, but what I want to do, is read a pdf file, make various modifications, and save the modified pdf over the original file. As of now, I am able to save the modified pdf to a separate file, but I am looking to replace the original, not create a new file.
Here is my current code:
from pyPdf import PdfFileWriter, PdfFileReader
output = PdfFileWriter()
input = PdfFileReader(file('input.pdf', 'rb'))
blank = PdfFileReader(file('C:\\BLANK.pdf', 'rb'))
# Copy the input pdf to the output.
for page in range(int(input.getNumPages())):
output.addPage(input.getPage(page))
# Add a blank page if needed.
if (input.getNumPages() % 2 != 0):
output.addPage(blank.getPage(0))
# Write the output to pdf.
outputStream = file('input.pdf', 'wb')
output.write(outputStream)
outputStream.close()
If i change the outputStream to a different file name, it works fine, I just cant save over the input file because it is still being used. I have tried to .close() the stream, but it was giving me errors as well.
I have a feeling this has a fairly simple solution, I just haven't had any luck finding it.
Thanks!
