unicode - Python BeautifulSoup string to float -

-

i have downloaded data set in xml format online webpage. have extracted values tag using beautifulsoup library of python. gives me unicode values.

graphs = soup.graphs c = 0 q in graphs:     name = q['title']     data = {}      r in graphs.contents[c]:         print float(str(unicode(r.string)))         data[r['xid']] = unicode(r.string)     c = c + 1      result[name] = [data[k] k in key]

the source http://charts.realclearpolitics.com/charts/1171.xml

and want make r.string float type

so did

print float(str(unicode(r.string))) print float(unicode(r.string))

but met err

file "<ipython-input-142-cf14a8845443>", line 73     print float(unicode(r.string)))                               ^ syntaxerror: invalid syntax

how do?

first error imbalanced round brackets.

print float(str(unicode(r.string))))                                    ^ 4th here

second error, check value whether none or not before making operation. otherwise you'll error valueerror: not convert string float: none

so fix be:

if(r.string != none):     print float(str(unicode(r.string)))
