python uses pandas to convert excel files to txt files

There are many ways for python to swap data for txt, and you can do so using the xlrd library. I am lazy and do not want to use too many plug-ins, using the existing library pandas to convert excel files to txt files.

Direct code:

'''
function Will: excel File conversion to text

import pandas as pd
import re
import codecs
 
# will excel into txt file 
def exceltotxt(excel_dir, txt_dir): 
 with codecs.open(txt_dir, 'w', 'utf-8') as f:
 neg=pd.read_excel(excel_dir, header=None, index=None)
 f.write(neg.to_string())
 
# Removes the number and space at the beginning of the record line 
def del_linehead_number_speace(orig_txt_dir,saveas_txt_dir):
 with open(orig_txt_dir,'r+') as f, open(saveas_txt_dir,'r+') as fw:
 lines = f.readlines()
 print(len(lines)) # The number of rows 
 texts = [re.sub(r'(\d)+(\s)+','',lines[num]) for num in range(len(lines)) ]
 
 texts = list(set(texts)) # De-duplication this line if you want to keep duplicate notes 
 
 line_num = len(texts)
#  for num in range(line_num):   # View the converted text 
#  print(texts[num])
 fw.writelines(texts)
 
exceltotxt('./data/neg.xls', './data/neg_temp.txt') 
del_linehead_number_speace('./data/neg_temp.txt','./data/neg.txt')
