pandas to_html no value representation - python

When I run the line below, the NaN number in the dataframe does not get modified. Utilizing the exact same argument with .to_csv(), I get the expected result. Does .to_html require something different?
df.to_html('file.html', float_format='{0:.2f}'.format, na_rep="NA_REP")

It looks like the float_format doesn't play nice with na_rep. However, you can work around it if you pass a function to float_format that conditionally handles your NaNs along with the float formatting you want:
>>> df
Group Data
0 A 1.2225
1 A NaN
Reproducing your problem:
>>> out = StringIO()
>>> df.to_html(out,na_rep="Ted",float_format='{0:.2f}'.format)
>>> out.getvalue()
<table border="1" class="dataframe">
<thead>
<tr style="text-align: right;">
<th></th>
<th>Group</th>
<th>Data</th>
</tr>
</thead>
<tbody>
<tr>
<th>0</th>
<td> A</td>
<td>1.22</td>
</tr>
<tr>
<th>1</th>
<td> A</td>
<td> nan</td>
</tr>
</tbody>
So you get the proper float precision but not the correct na_rep. But the following seems to work:
>>> out = StringIO()
>>> fmt = lambda x: '{0:.2f}'.format(x) if pd.notnull(x) else 'Ted'
>>> df.to_html(out,float_format=fmt)
>>> out.getvalue()
<table border="1" class="dataframe">
<thead>
<tr style="text-align: right;">
<th></th>
<th>Group</th>
<th>Data</th>
</tr>
</thead>
<tbody>
<tr>
<th>0</th>
<td> A</td>
<td>1.22</td>
</tr>
<tr>
<th>1</th>
<td> A</td>
<td> Ted</td>
</tr>
</tbody>

How to get text from nested html table with beautifulsoup?

Within each of the main tables respectively, there are two tables nested of which the first one contains the data A_A_A_A that i want to extract to a pandas.dataframe
<table>
<tr valign="top">
<td> </td>
<td>
<br/>
<center>
<h2>asd</h2>
</center>
<h4>asd</h4>
<table>
<tr>
</tr>

I figured that because of the limited availiability of attributes the only way to go forward would be an iteration over a td siblings with .next_siblings and if needed .next_elements
data1 = []
for item in soup.find_all('td', attrs={'width': '2%'}):
data = item.find_next_sibling().text
data1.append(data)
returns and empty list []. Now i dont know forward because i cannot identify any other helpful attributes/classes that would help me get to the middle td that contains the information.
.find_next(name=None, attrs={}, text=None, **kwargs)
Returns the first item that matches the given criteria and appears after this Tag in the document. So in your case:
item = soup.find('td', attrs={'width': '2%'})
data = item.find_next('td').text
Note that, I removed for loop since the desired data is coming after first td with width: '2%'. After running this, data will be:
' A_A_A_A A_A_A_A 111-222 '
I took #Wiktor Stribiżew answer from here regex for loop over list in python
and kind of merged it with yours #Rustam Garayev
item = soup.find_all('td', attrs={'width': '2%'})
data = [x.find_next('td').text for x in item]
since i needed not only the first AAAA but from all the following tables as well. The code above gives this output:
['A_A_A_A',
'\xa0',
'A_A_A_A',
'\xa0', ...]
which is good enough for my purpose. I think the '\xa0' comes from it trying to do the find_next on the third td sibling, which does not have a consecutive.

Regex html dynamic table

I have stuck with regex syntax. I am trying to create a regex for html code, that looks for a specific string, which is located in a table and gives you back the next column value next to our search string.
[u'<table> <tr> <td>Ingatlan \xe1llapota</td> <td>fel\xfaj\xedtott</td> </tr> <tr> <td>\xc9p\xedt\xe9s \xe9ve</td> <td>2018</td> </tr> <tr> <td>Komfort</td> <td>luxus</td> </tr> <tr> <td>Energiatan\xfas\xedtv\xe1ny</td> <td class="is-empty">nincs megadva</td> </tr> <tr> <td>Emelet</td> <td>1</td> </tr> <tr> <td>\xc9p\xfclet szintjei</td> <td class="is-empty">nincs megadva</td> </tr> <tr> <td>Lift</td> <td>van</td> </tr> <tr> <td>Belmagass\xe1g</td> <td>3 m vagy magasabb</td> </tr> <tr> <td>F\u0171t\xe9s</td> <td>g\xe1z (cirko)</td> </tr> <tr> <td>L\xe9gkondicion\xe1l\xf3</td> <td>van</td> </tr> </table>', u'<table> <tr> <td>Akad\xe1lymentes\xedtett</td> <td>nem</td> </tr> <tr> <td>F\xfcrd\u0151 \xe9s WC</td> <td>k\xfcl\xf6n \xe9s atlan \xe1llapota')
So I would like to create a regex to look for "Ingatlan \xe1llapota" and return "fel\xfaj\xedtott":
Ingatlan \xe1llapota fel\xfaj\xedtott
My current regex expression is the following: \bIngatlan állapota\s+(.*)
I would need to incorporate the td tags and to limit how long string would it return after the search string(Ingatlan állapota)
Any help is much appreciated. Thanks!
As pointed out before use xpath or css instead:
import scrapy
class txt_filter:
sterm='Ingatlan \xe1llapota'
txt= '''<table> <tr> <td>Ingatlan \xe1llapota</td> <td>fel\xfaj\xedtott</td> </tr> <tr> <td>\xc9p\xedt\xe9s \xe9ve</td> <td>2018</td> </tr> <tr> <td>Komfort</td> <td>luxus</td> </tr> <tr> <td>Energiatan\xfas\xedtv\xe1ny</td> <td class="is-empty">nincs megadva</td> </tr> <tr> <td>Emelet</td> <td>1</td> </tr> <tr> <td>\xc9p\xfclet szintjei</td> <td class="is-empty">nincs megadva</td> </tr> <tr> <td>Lift</td> <td>van</td> </tr> <tr> <td>Belmagass\xe1g</td> <td>3 m vagy magasabb</td> </tr> <tr> <td>F\u0171t\xe9s</td> <td>g\xe1z (cirko)</td> </tr> <tr> <td>L\xe9gkondicion\xe1l\xf3</td> <td>van</td> </tr> </table>', u'<table> <tr> <td>Akad\xe1lymentes\xedtett</td> <td>nem</td> </tr> <tr> <td>F\xfcrd\u0151 \xe9s WC</td> <td>k\xfcl\xf6n \xe9s atlan </td></tr></table>
'''
resp = scrapy.http.response.text.TextResponse(body=txt,url='abc',encoding='utf-8')
print(resp.xpath('.//td[.="'+sterm+'"]/following-sibling::td[1]/text()').extract())
Result:
$ python3 so_51590811.py

add icon to particular rows in django template table

I am working on python Django templates in which I have a table having column as id, factor A, factor B, factor C. Values for id, factor A, factor B and factor C respectively are 79, 0.56, 1.1, 1.3.
The code for the html template is like this:
<table class="table table-bordered">
<thead>
<tr>
<th class="text-center">id</th>
<th class="text-center">Factor A</th>
<th class="text-center">Factor B</th>
<th class="text-center">Factor C</th>
</tr>
</thead>
<tbody >
<tr ng-class="{'info':aggregateData.Mode, 'closed':!aggregateData.Open}">
<td class="text-center">{{aggregateData.id}}</td>
<td class="text-center">{{aggregateData.factor_a}}</td>
<td class="text-center">{{aggregateData.factor_b}}</td>
<td class="text-center">{{aggregateData.factor_c}}</td>
</tr>
</tbody>
</table
I want to add a clickable icon to this similar like this for rows having aggregateData.Open true.
Can someone suggest a way how I can achieve this.
Try this.
<table class="table table-bordered">
<thead>
<tr>
<th class="text-center">id</th>
<th class="text-center">Factor A</th>
<th class="text-center">Factor B</th>
<th class="text-center">Factor C</th>
</tr>
</thead>
<tbody >
<tr ng-class="{'info':aggregateData.Mode, 'closed':!aggregateData.Open}">
<td class="text-center">{{aggregateData.id}}</td>
<td class="text-center">{{aggregateData.factor_a}}</td>
<td class="text-center">{{aggregateData.factor_b}}</td>
<td class="text-center">{{aggregateData.factor_c}}</td>
{% if aggregateData.open == True %}
<td class="text-center">
<a href="https://www.google.co.in">
<img src="/path_toicon.png">
</a>
</td>
{% endif %}
</tr>

Python Selenium Copy Table Columns by Column Name

I have a table that has these headers, like this:
How would I select the whole column using xpath to store in an array.
I was hoping for different arrays, like:
courses = []
teacher = []
avg = []
Bare in mind these column don't have any ID's or classes, so I need a way to select just by using the name of the column.
Here is the code for the table:
<table border="0">
<tbody>
<tr>
<td nowrap="nowrap">Courses</td>
<td nowrap="nowrap">Teacher</td>
<td><select name="fldMarkingPeriod" onchange="switchMarkingPeriod(this.value);">
<option value="MP1">MP1</option>
<option selected="selected" value="MP2">MP2</option>
<option value="MP3">MP3</option>
</select>Avg</td>
</tr>
<tr>
<td nowrap="nowrap">[Course Name]</td>
<td nowrap="nowrap">[Teacher Name]</td>
<td>
<table width="100%" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td title="View Course Summary" width="70%">100%</td>
<td width="30%">A+</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr>
<td nowrap="nowrap">[Course Name]</td>
<td nowrap="nowrap">[Teacher Name]</td>
<td>
<table width="100%" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td title="View Course Summary" width="70%">100%</td>
<td width="30%">A+</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr>
<td nowrap="nowrap">[Course Name]</td>
<td nowrap="nowrap">[Teacher Name]</td>
<td>
<table width="100%" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td title="View Course Summary" width="70%">100%</td>
<td width="30%">A+</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>
Any ideas? Thanks.
Not sure why exactly you need the data by columns, but here is a sample implementation:
courses = []
teachers = []
avgs = []
for row in table.find_elements_by_css("table > tbody > tr")[1:]:
course, teacher, _, avg = [td.text for td in row.find_elements_by_xpath(".//td")]
courses.append(course)
teachers.append(teacher)
avgs.append(avg)

Xpath get data if conditions is satisfied in scrapy

I am using scrapy to extract data.
There are thousands of product which i am scraping
The problem is the data on these pages is not consistent
ie.
<table class="c999 fs12 mt10 f-bold">
<tbody><tr>
<td width="16%">Type</td>
<td class="c222">Kurta</td>
</tr>
<tr>
<td>Fabric</td>
<td class="c222">Cotton</td>
</tr>
<tr>
<td>Sleeves</td>
<td class="c222">3/4th Sleeves</td>
</tr>
<tr>
<td>Neck</td>
<td class="c222">Mandarin Collar</td>
</tr>
<tr>
<td>Wash Care</td>
<td class="c222">Gentle Wash</td>
</tr>
<tr>
<td>Fit</td>
<td class="c222">Regular</td>
</tr>
<tr>
<td>Length</td>
<td class="c222">Knee Length</td>
</tr>
<tr>
<td>Color</td>
<td class="c222">Brown</td>
</tr>
<tr>
<td>Fabric Details</td>
<td class="c222">Cotton</td>
</tr>
<tr>
<td>
Style </td>
<td class="c222"> Printed</td>
</tr>
<tr>
<td>
SKU </td>
<td id="qa-sku" class="c222"> SR227WA70ROJINDFAS</td>
</tr>
<tr>
<td></td>
</tr>
</tbody></table>
So these rows are not consistent .
Sometimes the "Type" is at first position and sometimes it is at second.
I wrote the code to loop through the values and compare the value of 1st td if it is "Type" the get the value of its corresponding td but it is not working
Here is the code.
table_data = response.xpath('//*[#id="productInfo"]/table/tr')
for data in table_data:
name = data.xpath('td/text()').extract()
What should i do??
You can try using the following xpath :
name = data.xpath("td[position()=(count(../../tr/td[.='Type']/preceding-sibling::td)+1)]/text()").extract()
Above xpath filters <td> by position, returning only <td> in position equal to position of <td>Type</td>. Getting position of <td>Type</td> done by counting number of it's preceding sibling <td> plus one.
If you want to get sibling node of td containing string 'Type' no matter what is position of this td you can try following xpath:
//td[contains(text(),'Type')]/following-sibling::td/text()
Try this,
In [29]: response.xpath('//table[#class="c999 fs12 mt10 f-bold"]/tr[contains(td/text(), "Type")]/td[contains(text(), "Type")]/following-sibling::td/text()|//table[#class="c999 fs12 mt10 f-bold"]/tr[contains(td/text(), "Type")]/td[contains(text(), "Type")]/preceding-sibling::td/text()').extract()
Out[29]: [u'Kurta']
no matter whether td is coming after Type or before Type, This will work.
//table/tbody/tr/td[.="Fabric"]/../td[2]/text()
Did it with the above code
