How to remove the special character '^' in a python string without removing whitespace wit-CodePudding

i've been wondering how to remove the special character '^' in a python string , it seems like it doesn't count like the other special characters.

I actually was trying to remove some special characters in a dataframe by using this code below :

def remove_special_characters(text, remove_digits=True):
    text=re.sub(r'[^a-zA-z0-9\s] ','',text)
    
    return text


df['review']=df['review'].apply(remove_special_characters)

but the symbol '^' is still appearing in my data , do you know some code to remove it please ?

CodePudding user response：

You can escape special characters:

r'[\^a-zA-z0-9\s] '

But the use case you're tackling is already addressed by translate(), without any need to resort to power tools like regexes.

https://docs.python.org/3/library/stdtypes.html#str.maketrans

You're incurring the cost of parsing / compiling the regex N times, when a single time would suffice. Consider defining this:

pattern = re.compile(r'[\^a-zA-z0-9\s] ')

It's actually still not working. What i'm searching for , is to get rid of the character '^' in a data , for example in the string 'bat^tle' i want it to be 'battle'.
