CvVideoWriter* writer = 0; //保存就加上这句int isColol=1; int frameW=640; int frameH=480; writer=cvCreateVideoWriter("out.avi",CV_FOURCC('F',...

表头其实就是"xx","xx","xx" 分割的txt一样数据。不信你用python直接读出来试试看就知道了,用记事本打开看一下。不过得注意转移哦~~掌握了这点,你可以自己写python csv读写模块~~

with open('ttt.csv','w') as fh: writer = csv.writer(fh,lineterminator='\n') #一次写入一行数据 for item in data: writer.writerow(item) #一次写入多行数据 writer.writerows(data)加一个linwterminator='\n'参数

Python文档中有提到: open('eggs.csv', newline='') 也就是说,打开文件的时候多指定一个参数。Python文档中也有这样的示例: import csvwith open('eggs.csv', 'w', newline='') as csvfile: spamwriter = csv.writer(csvfile, delimiter=' ',...

import csvTitle = ['Name','Age','Sex']Name = ['张三','李四','王二']Age = ['30','20','10']Sex = ['男','男','未知']for i in range(len(Title)): list=[] list.append(Name[i]) list.append(Age[i]) list.append(Sex[i]) print(list)#把这...

import csvcsvfile = file('csvtest.csv', 'wb')writer = csv.writer(csvfile)writer.writerow(['id', 'url', 'keywords'])data = [ ('1', 'http://www.xiaoheiseo.com/', '小黑'), ('2', 'http://www.baidu.com/', '百度'), ('3', 'http://www....

# -*- coding: utf8 -*-import csvl = [['1', 'Wonderful Spam'],['2', 'Lovely Spam']]#模拟数据写入一个csvwith open('eggs.csv', 'w', newline='') as csvfile: spamwriter = csv.writer(csvfile, delimiter=',', quotechar='"', quoting=csv...

#coding =utf-8 reader = open('test.txt').readlines() n=0 for len in reader: writer=open(str(reader.index(len)+1)+'.txt','w') if (len.find('\n')>0): for n in range(0,10): writer.write(len[:-1]+reader[n]) else: for n in range(0,1...

import csvwriter = csv.writer(file('test.csv', 'wb'))writer.writerow(['1', '2', '3']) 测试代码如上,writerow写入一行后,会自动换行到下一行,这是正常的。
