我正在尝试美丽的汤,并使用下面的代码提取一些数据Python 如何从BeautifulSoup中的find_all结果中排除标记,python,beautifulsoup,Python,Beautifulsoup,我正在尝试美丽的汤,并使用下面的代码提取一些数据 response = requests.get(url_fii, headers=headers) response.encoding = 'utf-8' soup = BeautifulSoup(response.text,'html.parser') print (soup) 我得到以下输出: <table class="holiday_list" width="100%"> <tr> <th colspan
response = requests.get(url_fii, headers=headers)
response.encoding = 'utf-8'
soup = BeautifulSoup(response.text,'html.parser')
print (soup)
我得到以下输出:
<table class="holiday_list" width="100%">
<tr>
<th colspan="5" style="text-align:center">Heading line</th>
</tr>
<tr>
<th style="text-align:center">Category</th>
<th style="text-align:center">Date</th>
<th style="text-align:center">Value 1</th>
<th style="text-align:center">Value 2</th>
<th style="text-align:center">Value 3</th>
</tr>
<tr class="alt">
<td class="first"> Quantity</td>
<td class="date">09-Apr-2020</td>
<td class="number">7277.03</td>
<td class="number">5539.41</td>
<td class="number">1737.62</td>
</tr>
</table>
输出:
Heading line
Category

Value 1
Value 2
Value 3
Quantity
09-Apr-2020
7277.03

唯一不需要的部分是“航向线”。由于它也包含在
for p in soup('tr')[1:]:
print(p.text)
有关切片表示法的更多信息,请参见此页。可以使用如下切片表示法跳过数组的第一个元素:
for p in soup('tr')[1:]:
print(p.text)
有关切片表示法的更多信息,请参见此部分。基于上述答案,以下是我现在使用的代码:
response = requests.get(url_fii, headers=headers)
response.encoding = 'utf-8'
soup = BeautifulSoup(response.text,'lxml')
for p in soup('tr')[1:]:
binNames = p.find_all('th')
binValues = p.find_all('td')
nBins = 0
nValues = 0
#The below section is for calculating the size of binNames. I didn't know of a better way than this.
for i in binNames:
if len(i) > 0:
nBins += 1
#Now we print the binNames
if nBins > 0:
for i in range(nBins):
print(binNames[i].text)
#The below section is for calculating the size of binValues. I didn't know of a better way than this.
for i in binValues:
if len(i) > 0:
nValues += 1
#Now we print the binValues
if nValues > 0:
for i in range(nValues):
print(binValues[i].text)
根据以上答案,以下是我现在使用的代码:
response = requests.get(url_fii, headers=headers)
response.encoding = 'utf-8'
soup = BeautifulSoup(response.text,'lxml')
for p in soup('tr')[1:]:
binNames = p.find_all('th')
binValues = p.find_all('td')
nBins = 0
nValues = 0
#The below section is for calculating the size of binNames. I didn't know of a better way than this.
for i in binNames:
if len(i) > 0:
nBins += 1
#Now we print the binNames
if nBins > 0:
for i in range(nBins):
print(binNames[i].text)
#The below section is for calculating the size of binValues. I didn't know of a better way than this.
for i in binValues:
if len(i) > 0:
nValues += 1
#Now we print the binValues
if nValues > 0:
for i in range(nValues):
print(binValues[i].text)
将“tr”改为“td”不是更好吗
对于汤中的o('td'):
您可以简单地将用于汤中的p('tr')[1://code>@Junitar您的建议奏效了。谢谢。如果你能在答案中解释会更好。@r-初学者如果我同意你的建议,我想要的一些输出将被忽略。将“tr”改为“td”不是更好吗对于汤中的o('td'):
