pyPDF2 PDFMerger close pensding file - japo85 - Jul-27-2022
Hello to everyone!
I have a problem using pyPDF2: I merge some pdf in a directory and I want to delete it after the job is done, but when I try to do it, I can't because one of them (the single pdf) was open by the pdfmerger and I can't delete it. The error is:
Error:Error in line 395: [WinError 32] Impossibile accedere al file. Il file รจ utilizzato da un altro processo: 'S:\\QUAREP\\Controlli\\12000609\\00_Report\\Vecchio_Nuovo\\temp\\12000609_220726_IP_Figura_2_su_12000609_220616_IP_Figura_2.pdf' Traceback (most recent call last): File "Vecchio_Nuovo_Da_CAD_Pdf_Merge_Snellito.py", line 396, in <module> File "shutil.py", line 513, in rmtree return _rmtree_unsafe(path, onerror) File "shutil.py", line 397, in _rmtree_unsafe onerror(os.unlink, fullname, sys.exc_info()) File "shutil.py", line 395, in _rmtree_unsafe os.unlink(fullname)rootDir=temp_path for dirName,subDir, fileList in os.walk(rootDir, topdown=False): merger = PdfFileMerger() for fname in fileList: merger.append(PdfFileReader(open(os.path.join(dirName, fname),'rb'))) print (fname) merger.write(str(path2)+(nome_confronto)+".pdf") folder=temp_path for filename in os.listdir(folder): file_path = os.path.join(folder, filename) try: if os.path.isfile(file_path) or os.path.islink(file_path): os.unlink(file_path) elif os.path.isdir(file_path): shutil.rmtree(file_path) except Exception as e: print('Failed to delete %s.

pdfmerger is not leaving the file open, you are. Here you open a file and never close it.
merger.append(PdfFileReader(open(os.path.join(dirName, fname),'rb')))I would use a context manager to automatically close the file.
with open(os.path.join(dirName, fname),'rb') as file: merger.append(PdfFileReader(file))

Thank you very much!! It works perfectly!
