Find on beautiful soup in loop returns TypeError
Solution 1
The Basic Issue
The parser is behaving correctly. You are just using the same expressions to parse different types of elements.
Revised code
Here is a snippet, focusing only on returning scraped lists. Once you have the lists, you can format the text table easily:
import BeautifulSoup
def get_queue(data):
# Args:
# data: string, contains the html to be scraped
soup = BeautifulSoup.BeautifulSoup(data)
stable = soup.find('table')
header = stable.findAll('th')
headers = [ th.text for th in header ]
cells = [ ]
rows = stable.findAll('tr')
for tr in rows[1:-2]:
# Process the body of the table
row = []
td = tr.findAll('td')
row.append( td[0].find('a').text )
row.append( td[1].find('a').text )
row.extend( [ td.text for td in td[2:] ] )
cells.append( row )
footer = rows[-1].find('td').text
return headers, cells, footer
Output
headers, cells, and footer, cells can now be fed into a texttable formatting function:
import texttable
def show_table(headers, cells, footer):
retval = ''
table = texttable.Texttable()
table.header(headers)
for cell in cells:
table.add_row(cell)
retval = table.draw()
return retval + '\n' + footer
print show_table(headers, cells, footer)

There are x songs in the queue with a total length of x:y:z.
Solution 2
The reason you're getting the error TypeError: find() takes no keyword arguments is because you are actually calling find() on a string.
string find
find is a python string method that takes no keyword arguments. Example:
>>> 'hello'.find('l')
2
>>> 'hello'.find('l', foo='bar')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: find() takes no keyword arguments
beautifulsoup find
beautifulsoup's Tag also has a find method, which is what you were trying to use.
The bottom line
At some point in your code, you ended up calling the string find, when you wanted to be working with a Tag.
Python uses duck typing, which can cause confusion in cases like this.

I'm trying to scrape a table on an ajax page with Beautiful Soup and print it out in table form with the TextTable library.
import BeautifulSoup import urllib import urllib2 import getpass import cookielib import texttable cj = cookielib.CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj)) urllib2.install_opener(opener) ... def show_queue(): url = 'https://www.animenfo.com/radio/nowplaying.php' values = {'ajax' : 'true', 'mod' : 'queue'} data = urllib.urlencode(values) f = opener.open(url, data) soup = BeautifulSoup.BeautifulSoup(f) stable = soup.find('table') table = texttable.Texttable() header = stable.findAll('th') header_text = [] for th in header: header_append = th.find(text=True) header.append(header_append) table.header(header_text) rows = stable.find('tr') for tr in rows: cells = [] cols = tr.find('td') for td in cols: cells_append = td.find(text=True) cells.append(cells_append) table.add_row(cells) s = table.draw print s ...Although the URL for the HTML in question I'm trying to scrape is shown in the code, here is an example of it:

TypeError: find() takes no keyword argumentson the lineheader_append = th.find(text=True). I'm sort of stumped, as it seems that I'm doing what is shown in code examples and it seems it should work, yet it doesn't.In short, how do I fix the code so that there is no TypeError and what am I doing wrong?
Edit: Articles and documentation that I referred to when writing the script:
