重命名pdf重命名pdf文件，其文本内容位于特定位置

问题描述

我找不到使用x,y函数重命名文件的方法。 示例：

enumerate

如何转换输出中的字符串以将其用作文件名？

解决方法

感谢您的回答。

我的想法是根据（相同pdf文件的）特定位置的内容动态重命名pdf文件。由于这些都是工资单，因此所有文件的员工注册号和姓名都位于同一位置。

import os,PyPDF2,re
def rename_pdfs(extraced_pdf_folder,rename_folder):
# traverse down through the root directory to sub-directories
for root,dirs,files in os.walk(extraced_pdf_folder):
for filename in files:
basename,extension = os.path.splitext(filename)
# if a file is a pdf

# if extension == ".pdf":
#   # create a reference to the full filename path
fullpath = root + "\\" + basename + extension
#   # open the individual pdf
pdf_file_obj = open(fullpath,"rb")
pdf_reader = PyPDF2.PdfFileReader(pdf_file_obj)
#   # access the individual page
page_obj = pdf_reader.getPage(0)
#   # extract the the text
pdf_text = page_obj.extractText()
# use enumerate to find information
for position,line in enumerate(pdf_text):
lines_to_read [1280,1281,1282,1283,1284,1285,1286,1287,1288,1289,1290,1291,1292,1293,1294,1295,1296,1297,1298,1299,1300,1301,1302,1303,1304,1305,1306,13 
07,1308]
doc_num = "nome "
pdf_file_obj.close()
          
if position in lines_to_read:
    #THIS PRINT IN THE CONSOLE FOR EACH PDF THE EMPLYE NAME AND SURNAME
    print (line,end="")
    #OS RENAME WITH %LINE GIVE ME ONLY A CARACTER

    os.rename(fullpath,root + "\\" + doc_num + "%s.pdf"%line)
    
    # parameter variables
    root_dir = r"C:\query\pdf\rename_pdf"
    extract_to = r"C:\query\pdf\extracted"
    rename_to = r"C:\query\pdf\renamed"

    

    rename_pdfs(extract_to,rename_to)

,

我使用链接的正则表达式解决了它。

谢谢大家

for index in re.finditer("SHERAZ0101",pdf_text):
  #oc_ext = pdf_text[index.start()+506:index.start()+531]
  doc_ext = pdf_text[index.end()+488:index.end()+521] +pdf_text[index.end()+471:index.end()+477]
  
  doc_num = "" + doc_ext.replace('\n\n',"").replace('/',"-").replace('SPECI',"").replace(":","").replace("  ","").replace(" .pdf",".pdf")
  pdf_file_obj.close()
  print(doc_ext)
  # rename the pdf based on the information in the pdf
  os.rename(fullpath,rename_folder + "\\" + doc_num + ".pdf")
