Question

我目前正在使用此代码从网站抓取一组值：

#import libraries
import requests
from bs4 import BeautifulSoup
import numpy as np

        for reviewtype in soup2.findAll('div', {'row_label'}):
            if 'Excellent' or 'Very Good' or 'Average' or 'Poor' or 'Terrible' in reviewtype.text:
                reviewtype.text.strip()
                reviewbar = reviewtype.findNext('span')
                reviewfill = reviewbar.findNext('span')
                reviewnum = reviewfill.findNext('span')
                reviewnumlist = reviewnum.text.encode('ascii', 'ignore').strip().split(r'</span>')
                print np.array(reviewnumlist)

它提取数据如下：

['254']
['30']
['5']
['5']
['2']

我希望它能像这样出现：

['254'], ['30'], ['5'], ['5'], ['2']

但我目前的方法并不奏效。任何见解都会有所帮助

创建一个空列表，在最后添加相关项目并print，而不是在forloop内单独打印对象。

#import libraries
import requests
from bs4 import BeautifulSoup
import numpy as np

result = []
for reviewtype in soup2.findAll('div', {'row_label'}):
    if 'Excellent' or 'Very Good' or 'Average' or 'Poor' or 'Terrible' in reviewtype.text:
        reviewtype.text.strip()
        reviewbar = reviewtype.findNext('span')
        reviewfill = reviewbar.findNext('span')
        reviewnum = reviewfill.findNext('span')
        reviewnumlist = reviewnum.text.encode('ascii', 'ignore').strip().split(r'</span>')
        result.append(revirenumlist)
print result

将值列表转换为数组
