python中csv與txt文件轉換

如何將文件夾內圖片名稱寫入csv中

import os
import pandas as pd
data=[]
names = os.listdir(r"C:\Users\Administrator.SKY-20180518VHY\Desktop\1")  #路徑
for name in names:
    data.append([name,0])
print(data)    
name=['id','target']
test=pd.DataFrame(columns=name,data=data)
print(test)
test.to_csv(r"C:\Users\Administrator.SKY-20180518VHY\Desktop\3.csv",index=None)

將csv文件轉爲txt格式

import numpy as np
import pandas as pd
submit1_path="/home/dell/Desktop/12345_13.csv"
submit1=pd.read_csv(submit1_path)
#submit1.drop('Target',axis=1,inplace=True)
#submit1.Predicted=submit1.Predicted.apply(lambda x: "00"+str(int(x)+1))
#submit1.Predicted=submit1.Predicted.apply(lambda x: str(int(x)))
submit1.id=submit1.id.apply(lambda x: str(x))
#submit1.Id=submit1.Id.apply(lambda x: str(x).zfill(6))
submit1=submit1.sort_values('id',ascending=True)
submit1.to_csv("/home/dell/Desktop/test.txt",sep='\t',index=None,header=None)

將txt轉爲csv文件

#coding=utf-8
lines = open('/home/dell/Desktop/MM_TTA2.txt').readlines()
fp2 = open('/home/dell/Desktop/a8.csv','w')  #打開你要寫得文件test3.csv
for s in lines:
    fp2.write(s)
