我是靠谱客的博主过时飞机，最近开发中收集的这篇文章主要介绍python read file(f,csv)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

import csv

def readfile0():
    print('test read file')
    in_file = open('C:pythondemoLiaoXueFengdatalianjian_zufang_version_4.csv','r',encoding='UTF-8')
    content=in_file.read()
    print(content)

def readfile2():
    with open('C:pythondemoLiaoXueFengdatalianjian_zufang_version_4.csv','r',encoding='UTF-8') as fin:
        for line in fin:
            l = [line.split(',') for line in fin]
            print(l)


def csvreadfile():
    f= open('C:pythondemoLiaoXueFengdatalianjian_zufang_version_4.csv','r',encoding='UTF-8')
    s=csv.reader(f)
    l=list(s)
    print(l)

def wirtefile():
    in_file = open('C:pythondemoLiaoXueFengdatalianjian_zufang_version_4.csv','r',encoding='UTF-8')
    content=in_file.read()
    print(content)

    f=open('C:pythondemoLiaoXueFengdatagoog2.csv','w',encoding='UTF-8')
    f.write(content)

    f.close()
    in_file.close()

def wirtecsfile():
    f = open('C:pythondemoLiaoXueFengdatagoog2.csv', 'w', encoding='UTF-8')
    ow= csv.writer(f)
    ow.writerow('aaaaaaa')
    f.close()
