"\nRated\xa0\n           I have been to this place for dinner tonight.
        \nWell I didn't found anything extraordinary there but indeed a meal worth 
        the price. The number of barbeque item and other both were good.\n\nFood: 3.5/5\"

所以为了弄清楚这个标签,我用了

  val.text.replace('\t', '').replace('\n', '').encode('ascii','ignore').
decode("utf-8").replace('Rated','').replace('  ','')

I have been to this place for dinner tonight. Well I didn't found anything extraordinary there but indeed a meal worth the price. The number of barbeque item and other both were good. Food: 3.5/5

replace('\t', '').replace('\n', '').replace('  ','')

你可以用 .translate \n\t

>>> val.translate(None,'\n\t').replace('  ','')
"Rated I have been to this place for dinner tonight.Well I didn't found anything extraordinary there but indeed a meal worth the price. The number of barbeque item and other both were good.Food: 3.5/5"

这个 replace(' ','')

>>> re.sub(r'(\b  *\b)',' ',val.translate(None,'\n\t'))
"Rated I have been to this place for dinner tonight.Well I didn't found anything extraordinary there but indeed a meal worth the price. The number of barbeque item and other both were good.Food: 3.5/5"

replace 但我仍然认为这是最好的方法:

import string
val = """\nRated\xa0\n           I have been to this place for dinner tonight.
        \nWell I didn't found anything extraordinary there but indeed a meal worth 
        the price. The number of barbeque item and other both were good.\n\nFood: 3.5/5\"""
        """
print(''.join([i for i in ' '.join(val.split()) if i in string.ascii_letters+' ']))

Rated I have been to this place for dinner tonight Well I didnt found anything extraordinary there but indeed a meal worth the price The number of barbeque item and other both were good Food
