直接贴代码啦：


#coding=utf-8
import pandas as pd
def arff_to_csv(fpath):
  #读取arff数据
  if fpath.find('.arff') <0:
    print('the file is nott .arff file')
    return
  f = open(fpath)
  lines = f.readlines()
  content = []
  for l in lines:
    content.append(l)
  datas = []
  for c in content:
    cs = c.split(',')
    datas.append(cs)
  #将数据存入csv文件中
  df = pd.DataFrame(data=datas,index=None,columns=None)
  filename = fpath[:fpath.find('.arff')] + '.csv'
  df.to_csv(filename,index=None)
