Python and string accents

问题

I am making a web scraper.
I access google search, I get the link of the web page and then I get the contents of the <title> tag.
The problem is that, for example, the string "P\xe1gina N\xe3o Encontrada!" should be "Página Não Encontrada!". I tried do decode to latin-1 and then encode to utf-8 and it did not work.

    r2 = requests.get(item_str)
    texto_pagina = r2.text
    soup_item = BeautifulSoup(texto_pagina,"html.parser")
    empresa = soup_item.find_all("title")
    print(empresa_str.decode('latin1').encode('utf8'))

Can you help me, please? Thanks !

回答1:

You can change the retrieved text variable to something like:

string = u'P\xe1gina N\xe3o Encontrada!'.encode('utf-8')

After printing string it seemed to work just fine for me.

Edit

Instead of adding .encode('utf8'), have you tried just using empresa_str.decode('latin1')?

As in:

string = empresa_str.decode('latin_1')

Not the most elegant solution, but worked for me :

def remove_all(substr, str):
 index = 0
 length = len(substr)
 while string.find(str, substr) != -1:
    index = string.find(str, substr)
    str = str[0:index] + str[index+length:]
 return str
