remove special character from string in python

Like i have string variable which has value is given below

string_value = 'hello ' how ' are - you ? and/ nice to % meet # you'

Expected result:

hello how are you and nice to meet you

Solution

  • You could try just removing all non word characters:

    string_value = "hello ' how ' are - you ? and/ nice to % meet # you"
output = re.sub(r'\s+', ' ', re.sub(r'[^\w\s]+', '', string_value))
print(string_value)
print(output)

    This prints:

    hello ' how ' are - you ? and/ nice to % meet # you
hello how are you and nice to meet you

    The solution I used first targets all non word characters (except whitespace) using the pattern [^\w\s]+. But, there is then the chance that clusters of two or more spaces might be left behind. So, we make a second call to re.sub to remove extra whitespace.
