python 利用pandas将arff文件转csv文件

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)
