1. Download Atom

1. Official website: Atom official website

2. Open this webpage, you can see that Atom is for the operating system Windows7 or above version

3. Download is complete, double-click the exe

4. Loading interface

                                                                                                                

#1. Check Python library support

(1) First check in Settings whether has Python support

, blogger here Because the Python library is installed, Disable

is displayed (2) Click on the package name and we can also go to the web page to view related information about the package

2. Install Python’s IDE,

UI

,# that are suitable for Atom ##Server and

running tools

(1) Open cmd and run the following instructions to install python-language-server

pip install python-language-server[all]
Successful installation displays this interface:

(2) Installation supports various language IDEs UI interface, search atom-ide-ui

in

Install as shown in the picture

(3) Similarly, install ide-python

:

ide-python

(4) Finally

The most important, install the running toolatom-python-run

Press F5 to run, F6 to pause~

                                 

(5) The final downloaded package can be seen in this file C:\Users\your computer username\.atom\packages                          

*3. Running code example

1. Here I use my Python to crawl and download Baidu pictures

For example: Python implements crawling and downloading Baidu pictures

2.打开这个项目,菜单栏里点击File->Add Project Folder

3.Atom里打开这个download_picture.py(以杉原杏璃为关键字)

    """
    如果page_number为20,则百度图片每页显示20张图片,因此对于flip形式每页会多缓存(60-20=40)张,index形式每页会多缓存(30-20=10)张,
    所以,请求4次的话:
        flip应该是 20 × 4 + (60 - 20) = 120张图片,而不是60×4 = 240
        index应该是 20 × 4 + (30 - 20) = 90张图片,而不是30×4 = 120

    说白了,就是获取了重复的图片
    可以通过调节page_number变量查看
    """
    all_pic_urls = []
    while 1:#死循环
        if times > total_times:
            break
        print("第{}次请求数据".format(times + 1))
        url=getPage(keyword, times, page_number, pic_type)#输入参数:关键词,开始的页数,总页数
        print(url)#打印链接
        onepage_urls= get_onepage_urls(url)#index是30个图片的链接,flip是60个
        times += 1#页数加1
        if onepage_urls != 0:
            all_pic_urls.extend(onepage_urls)#列表末尾一次性追加另一个序列中的多个值
            #print("将要下载的图片数量变为:{}".format(len(all_pic_urls)))
    print("下载的图片总量变为:{}".format(len(all_pic_urls)))
    
 
    download_pic(list(set(all_pic_urls)),keyword, save_path)#set去除重复的元素(链接)

效果如下(可以看到很多警告,也支持ctrl+鼠标访问函数和变量):

4.我们点击F5,可以看到程序运行成功!!

是不是用这个IDE也很不错呢~
