python保存列表

##保存
ipTable=['123.111.111.1','111.111.111.1']
fileObject = open('sampleList.txt', 'w')  
for ip in ipTable:  
    fileObject.write(str(ip))  
    fileObject.write('\n') 
fileObject.close()  

##读取
f = open("sampleList.txt","r")   #设置文件对象
table = f.read()     #将txt文件的所有内容读入到字符串str中
f.close()   #将文件关闭
