importPDFResourceManager,PDFPageInterpreter
frompdfminer.converterimportTextConverter
frompdfminer..pdfpage
importPDFPage
defconvert_pdf_2_text(path):

rsrcmgr=PDFResourceManager()
retstr=StringIO()

device=TextConverter(rsrcmgr,retstr,codec='utf-8',laparams=LAParams())
interpreter=PDFPageInterpreter(rsrcmgr,device)

withopen(path,'rb')asfp:
forpageinPDFPage.get_pages(fp,set()):
interpreter.process_page(page)
text=retstr.getvalue()

device.close()
retstr.close()

returntext
