先看書，別用學習java、PHP那套做項目方法

不建議使用 urllib 庫，推薦 requests 庫

import requests
response = requests.get('https://www.baidu.com/')
response.encoding = 'utf-8'
print(response.text)

好像實現(xiàn)不了，echarts的餅圖的線啊啥的沒有自定義的功能

您好，請問下這個問題您解決了嗎？我也遇到了這種需求，能否一起探討下？感謝。

Quite simple:

"Hello,

你代碼都寫在div內(nèi)部了當然會按你顯示的那樣。一般都是下面這樣寫。

    var vds = document.createElement('script')
    vds.type = 'text/javascript'
    vds.async = true
    vds.src = (document.location.protocol === 'https:' ? 'https://' : 'http://') +
      'assets.growingio.com/vds.js'
    var s = document.getElementsByTagName('script')[0]
    s.parentNode.insertBefore(vds, s)

不是Ajax就是服務端渲染

在定位語句前面time.sleep一下試試

對樹遍歷，重新生成數(shù)組，前端做這工作，挺耗性能的，尤其數(shù)據(jù)量龐大的時候，可能會卡死，一般我們都讓后端處理好再給我們

sunburst沒有提供tooltip顯示item的name屬性，name在data中，所以可以在sunburst.data.emphasis設置

var data = [{
    name: 'Grandpa',
    emphasis: {
        itemStyle: {
            color: 'red'
        }
    },
    highlight: {
        itemStyle: {
            color: 'orange'
    }
    },
    downplay: {
        itemStyle: {
            color: '#ccc'
        }
    },
    children: [{
        name: 'Uncle Leo',
        value: 15,
        children: [{
            name: 'Cousin Jack',
            value: 2
        }, {
            name: 'Cousin Mary',
            value: 5,
            children: [{
                name: 'Jackson',
                value: 2
            }]
        }, {
            name: 'Cousin Ben',
            value: 4
        }]
    }, {
        name: 'Father',
        value: 10,
        children: [{
            name: 'Me',
            value: 5
        }, {
            name: 'Brother Peter',
            value: 1
        }]
    }]
}, {
    name: 'Nancy',
    children: [{
        name: 'Uncle Nike',
        children: [{
            name: 'Cousin Betty',
            value: 1
        }, {
            name: 'Cousin Jenny',
            value: 2
        }]
    }]
}];

option = {
    series: {
        type: 'sunburst',
        // highlightPolicy: 'ancestor',
        data: data,
        radius: [0, '90%'],
        label: {
            rotate: 'radial'
        }
    }
};

這個問題是不是跟你的需求一致？
https://stackoverflow.com/que...

/a/@href 好像是這么寫的

sea.distplot(x,hist_kws=dict(edgecolor='k'))

是不是你的類名沖突了？

expect+ssh-copy-id,前提知道每個ip和密碼。

數(shù)據(jù)溢出，將matrix類型轉(zhuǎn)為 float然后計算梯度

你需要看下post的數(shù)據(jù)是什么類型的，直接post字典不成功的話，把字典json.dumps()一下。看看是否成功

一個爬蟲類就可以解決。

yield Request（URL，callback）返回第一次爬取的鏈接。

然后用callback函數(shù)對返回鏈接進行再次爬取，接著再對爬取數(shù)據(jù)處理給item或者繼續(xù)yield Request也行。

callback就是回調(diào)的函數(shù)名。

不用存文檔里，那樣速度太慢了。

例子：類似于這種，有點偽代碼。

class MySpider(scrapy.Spider):
    name = 'zhilian_spider'
    allowed_domains = ['example.com']
    start_urls = [
        'http://www.zhaopin.com/citymap.html']
    yield scrapy.Request(url, callback=self.parse)

    def parse(self, response):
        ...
        yield scrapy.Request(url, callback=self.parse_jobs, dont_filter=True)

    def parse_jobs(self, response):
        ...
            yield item

建議研究一下scrapy
官網(wǎng)內(nèi)容：http://scrapy-chs.readthedocs...

filter和map是類似的，返回的也是一個迭代器，對傳入的可迭代對象的每一項用指定的函數(shù)進行篩選，轉(zhuǎn)化為list或者使用for循環(huán)就會一次性對每一項進行篩選，你可以試一試這一段代碼

for x in filter(lambda x % 2 == 0, range(10)):
    print(x)
