How to set a BeautifulSoup.Tag as a label in Gtk3 using Python

Question

I'm working on a program to fetch pictures from APOD web site and show its information (the part called Explanation in the site, right below the picture). I'm going to show a simplified class that implements only the part that picks the information about the picture:

import urllib2
import datetime

from BeautifulSoup import BeautifulSoup
from gi.repository import Gtk

class InfoAPOD(Gtk.Window):
    """View info about selected APOD image"""

    def __init__(self):
        """Initialize the window"""
        Gtk.Window.__init__(self)
        self.set_default_size(600, 500)
        self.set_position(Gtk.WindowPosition.CENTER)
        self.set_border_width(3)

        self.grid = Gtk.Grid()
        self.add(self.grid)

        self.scrolledwindow = Gtk.ScrolledWindow()
        self.scrolledwindow.set_vexpand(True)
        self.scrolledwindow.set_hexpand(True)
        self.grid.add(self.scrolledwindow)

        self.label = Gtk.Label()
        self.scrolledwindow.add_with_viewport(self.label)

        date = datetime.date.today()
        page = "ap" + date.strftime('%y%m%d') + ".html"
        base_url = "http://apod.nasa.gov/apod/"
        apod_url = base_url + page

        apod_htm = urllib2.urlopen(apod_url).read()
        soup = BeautifulSoup(apod_htm)
        tag_b = soup.findAll('b')
        tag_p = soup.findAll('p')

        apod_dat = date.strftime('%Y %h %d')
        apod_tit = tag_b[0].string.strip()
        apod_inf = str(tag_p[2])

        name = "APOD from " + apod_dat + " - " + apod_tit
        self.set_title(name)

        text = apod_inf.replace('<p>', '').replace('</p>', '')
        self.label.set_markup(text)
        self.label.set_justify(Gtk.Justification.LEFT)
        self.label.set_line_wrap(True)

def main():
    """Show the window"""
    win = InfoAPOD()
    win.connect('delete-event', Gtk.main_quit)
    win.show_all()
    Gtk.main()
    return 0

if __name__ == '__main__':
    main()

The problem is that the text lines are broken, and do not form a continuous paragraph (if you take a look at the APOD site you will understand what I mean). Maybe a picture is worth than thousands words:

In short, I'm using urllib2 to fetch the web page and BeautifulSoup to parse the tags, as shown in the code above. Then, I isolate the part of the information that I want (of type BeautifulSoup.Tag) and convert it in a string in order to set it as a label using markup. I've read some documentation/examples here and there about BeautifulSoup but I couldn't improve the appearance of the text.

Any advice in how to improve the appearance of text in the window is appreciated.

Do you want to remove the linebreaks? What about?

text = apod_inf.replace('<p>', '').replace('</p>', '').replace('\n', '')

And if you don't want to be that cluttered you can try something like:

foo.replace('\n\n', 'SOMETOKEN').replace('\n', 'SOMETOKEN', 1).replace('\n', '', 1).replace('SOMETOKEN', '\n')
