python3使用csv模块读写csv文件 读取csv文件: import csv #打开文件,用with打开可以不用去特意关闭file了,python3不支持file()打开文件,只能用open() with open("XXX.csv","r",encoding="utf-8") as csvfile: #读取csv文件,返回的是迭代类型 read = csv.reader(csvfile) for i in read: print(i) 存
一.自动输出中文字符集 select * from db into outfile 'test.csv' CHARACTER SET gbk fields terminated by ',' optionally enclosed by '"' escaped by '"' lines terminated by '\r\n'; 二.导出后转换字符集 转换成CSV文件,如果乱码将CSV已记事本打开另存为UTF8 select * from db into outfile 'test.c
csv数据:逗号分隔值,其文件以纯文本的形式存储表格数据(数据和文本).csv模块是python的内置模块,需要引用后再使用 csv.reader(csv_file) #使用with结构 with open("data/data.csv","r”,encoding="utf8") as fp: data=csv.reader(fp) #使用for迭代reader对象 for line in reader csv.writer(csv_file) #写入cs
也没啥,记下来怕忘了.说明都在代码里面: 麻蛋,这个着色好难看 import csv import json #从txt变为csv student_txt=[]; with open("student.txt",mode='r',encoding='utf-8')as student_txt_file_name: for i in student_txt_file_name.readlines(): student_txt.append(i.strip('\n').split(&quo
