How to use multiple replace together or at once, Python

I have some text which is not clear and have so many tags and ascii as follow,

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\"

So for making clear this tag I am using 

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

and using multiple times replace I got my o/p as -

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

I want to know that is there any way so I can use replace at once only for similar kind of replacement. like in this case - 

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

You can use .translate to delete \n\t and then use your replacement for the runs of spaces:

>>> 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"

The replace(' ','') will be problematic with runs of even spaces (they will just be deleted). You might consider a regex:

>>> 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"

Well even do i am not using replace, but i still think this is the best way:

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+' ']))

Output:

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
