python读txt的各种操作（逗号，tab键，空格隔开，转成list）

1、txt里面的数据都是逗号隔开的，一个逗号隔开的就是一个数据，把这些数据读取出来存到list中；

def dh_list(file):
    with open(file,"w+",encoding="utf-8") as f: 
        f.writelines([
            '我是哪吒,\n',
            'hello world,\n',
            'nice to meet you\n',
        ])
        f.seek(0) #把指针移到文件开头位置
        result=[]
        for line in f.readlines():#readlines以列表输出文件内容
            line=line.replace(",","").replace("\n","")#改变元素，去掉，和换行符\n,tab键则把逗号换成"/t",空格换成" "
            result.append(line)
    return result

print(dh_list('1.txt'))
#结果：['我是哪吒','hello world','nice to meet you']

2、txt里面数据，一行一个数据（key:value)，把这些数据读取出来存到list中；

def dict_list(file):    
    with open(file,"w+",encoding="utf-8") as f:        
        f.writelines([            'url:http://baidu/login,mobile_phone:13760246701,pwd:123456\n',     
'ur1:http://baidu/login,mobile_phone:15678934551,pwd:234555\n',    
'ur1:http://baidu/login,mobile_phone:15678934551,pwd:234555\n',    
'ur1:http://baidu/login,mobile_phone:15678934551,pwd:234555\n',   
'ur1:http:baidu/login,mobile_phone:15678934551,pwd:234555'        
                     ])        
        f.seek(0)        
        result=[]        
        for line in f.readlines():            
            dict1={}            
            for data1 in line.strip('\n').split(','):
                dict1[data1.split(':',1)[0]]=data1.split(':',1)[1]            						
            	result.append(dict1)    
    return result

print(dict_list("1.txt"))
#结果：[{"url:baidu/login","mobile_phone":"13760246701","pwd":"123456"}]
