I have tried with the replace in python. But it wouldn't work.

my_list=[['the',

 'production',

 'business',

 'environmentâxa0evaluating',

 'the'],

 ['impact',

 'of',

 'the',

 'environmental',

 'influences',

 'such'],

 ['as',

 'political',

 'economic',

 'technological',

 'sociodemographicâxa0']]

my_list.replace(u'xa0', ' ') and

my_list[0].replace(u'xa0', ' ')  

For this got the attribute error. AttributeError: 'list' object has no attribute 'replace' How to remove this unwanted string from the list my_list?

Use unicodedata library. That way you can save more information from each word.

import unicodedata

final_list = [[unicodedata.normalize("NFKD", word) for word in ls] for ls in my_list]

To also replace â with a

very_final_list = [[word.encode('ascii', 'ignore') for word in ls] for ls in final_list]

If you want to completely remove â then you can

very_final_list = [[word.replace('â', '') for word in ls] for ls in final_list]

and to remove b' in front of every string, decode it back to utf-8

So putting everything together,

import unicodedata

final_list = [[unicodedata.normalize("NFKD", word) for word in ls] for ls in my_list]

very_final_list = [[word.encode('ascii', 'ignore').decode('utf-8') for word in ls] for ls in final_list]

#very_final_list = [[word.replace('â', '') for word in ls] for ls in final_list]

And here is the final result:

[['the', 'production', 'business', 'environmenta evaluating', 'the'], ['impact', 'of', 'the', 'environmental', 'influences', 'such'], ['as', 'political', 'economic', 'technological', 'sociodemographica ']]

If you switch the very_final_list statements, then this is the output

[['the', 'production', 'business', 'environment evaluating', 'the'], ['impact', 'of', 'the', 'environmental', 'influences', 'such'], ['as', 'political', 'economic', 'technological', 'sociodemographic ']]

lst = 

for l in my_list:

    lst.append([s.replace(u'xa0','') for s in l])

Output:

[['the', 'production', 'business', 'environmentâevaluating', 'the'],

 ['impact', 'of', 'the', 'environmental', 'influences', 'such'],

 ['as', 'political', 'economic', 'technological', 'sociodemographicâ']]

Emmmm,The another answer,I think it break the structure of my_list.But it's easy too.Only one line.

Updated :
List of List Comprehension should make this work for you

[[w.replace("âxa0", " ") for w in words] for words in my_list]

Output

[['the', 'production', 'business', 'environment evaluating', 'the'],

['impact', 'of', 'the', 'environmental', 'influences', 'such'],

['as', 'political', 'economic', 'technological', 'sociodemographic ']]
