糗事百科图片文件夹在哪

你手机的的sd卡里面,文件管理有个“qsbk"命名的文件夹就是它,里面就只有图片,PS:图片你要先下载啊.......我也是糗友

oppo机上老是出现qsbk.app停止运行 怎么办

你好,停止运行的话你可以在设置--应用程序--全部--找到相应的程序--清理数据重启手机观察的。这里的清理数据不会丢失资料。游戏无反应或者反应慢,一般是以下几个因素导致的:1、一次运行多个应用程序,建议清理后台 2、下载了很多第三方软件,导致中毒或者不兼容。建议卸载非软件商店下载的软件 3、缓存文件过多长时间没有清理,建议清理缓存。清理缓存方法:在手机关机后,同时按电源键和音量减8秒左右,进入recovery模式,选择清除缓存,清理后重启手机,您再观察看看。清理缓存不会丢失资料,请您放心的,同时也请您不要选错。

若您还有其他的问题咨询,您可以进入OPPO企业平台向客服咨询提问喔!

-------------------------

vi items.py

from scrapy.item import Item,Field

class TutorialItem(Item):

# define the fields for your item here like:

# name = Field()

pass

class Qsbk(Item):

title = Field()

link = Field()

desc = Field()

-----------------------

vi qsbk/spiders/qsbk_spider.py

from scrapy.spider import Spider

class QsbkSpider(Spider):

name = "qsbk"

allowed_domains = ["qiushibaike.com"]

start_urls = [""]

def parse(self, response):

filename = response

open(filename, 'wb').write(response.body)

------------------------

然后我 scrapy shell 想先把网页取下来,再xpath里面的子节点(即一些内容)

这个想法应该没错吧,但是到scrapy shell 的时候网页内容就无法显示了,

错误反馈:

python 把list元素插入数据库

两种方法

1、python读取文件后,解析value中的id,存储到list中,再读另一个文件时,去list里判断是否已存在

2、python读取另一个文件后,解析values中的id,脚本直接去数据库判断是否存在

其实数据库可以设计id未主键,这样你直接insert即可,出错的话,数据库会容错

1.首先在下落过程中对小球b进行受力分析,下落过程中受到自身重力和绳子的拉力,绳子的拉力很好求,就是g*sin30,所以b小球的受到的合力为mg-mg*sin30=1/2*mg,b球的加速度为a=1/2g,所以b小球的落地速度v的平法=2*a*h=2*0.5*10*0.2=2,所以v=根号2。

2.由于a小球与b小球有绳子相连,所以速度大小和b小球相同,而经过受力分析,此时a球的受到的合力方向沿斜面向下,大小为mg*sin30,所以加速度a1为-1/2g,v的平方=2*a1*s,所以s=v的平方/2*0.5*g=2/(2*0.5*10)=1m
