我正在使用pdfminer使用python從pdf文件中提取數(shù)據(jù)。我想提取pdf中存在的所有數(shù)據(jù)，而不管它是圖像還是文本，無論它是什么。我們可以在一行中執(zhí)行此操作嗎（如果需要，可以執(zhí)行兩條操作，而無需進(jìn)行大量工作）。任何幫助表示贊賞。提前致謝

對于Python 3：
點(diǎn)安裝pdfminer.six
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
from io import StringIO
def convert_pdf_to_txt(path, codec='utf-8'):
rsrcmgr = PDFResourceManager()
retstr = StringIO()
laparams = LAParams()
device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
fp = open(path, 'rb')
interpreter = PDFPageInterpreter(rsrcmgr, device)
password = ""
maxpages = 0
caching = True
pagenos=set()
for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages, password=password,caching=caching, check_extractable=True):
interpreter.process_page(page)
text = retstr.getvalue()
fp.close()
device.close()
retstr.close()
return text

對于python3，還有另一個：pip install pdfminer3k
from pdfminer.pdfinterp import PDFResourceManager, process_pdf
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from io import StringIO
import time
from functools import wraps
def fn_timer(function)://this is for calculating the run time(function)
@wraps(function)
def function_timer(*args, **kwargs):
t0 = time.time()
result = function(*args, **kwargs)
t1 = time.time()
print ("Total time running %s: %s seconds" %
('test', str(t1-t0))
)
return result
return function_timer
@fn_timer
def convert_pdf(path, pages):
rsrcmgr = PDFResourceManager()
retstr = StringIO()
laparams = LAParams()
device = TextConverter(rsrcmgr, retstr, laparams=laparams)
fp = open(path, 'rb')
process_pdf(rsrcmgr, device, fp,pages)
fp.close()
device.close()
str = retstr.getvalue()
retstr.close()
return str
file = r'M:\a.pdf'
print(convert_pdf(file,[1,]))
