Commas, hyphen, semicolon, hash tags , punctuations are to be removed
You can also try the following:
import string
def clear_punctuation(s):
clear_string = ""
for symbol in s:
if symbol not in string.punctuation:
clear_string += symbol
return clear_string
print(clear_punctuation(‘“!!!test: remove full-stops, hashtags, symbols, commas, hyphen, semicolon etc from dataset using python for sentiment analysis?Commas, hyphen, semicolon, hash tags , punctuations are to be removed') )
# The aforementioned code removes most punctuation symbols. Nevertheless, if you want to remove specific items you may try the following:
string_punctuation = ".#,_;"
def remove_punctuation(s):
no_punct = ""
for letter in s:
if letter not in string_punctuation:
no_punct += letter
return no_punct
print(clear_punctuation('"test!!!remove full-stops, hashtags, symbols, commas, hyphen, semicolon etc from dataset using python for sentiment analysis?Commas, hyphen, semicolon, hash tags , punctuations are to be removed') )
Hi, you can use str.replace("old", "new"); function to replace special characters
Regards

I would use Regular Expressions for this task. I have used it for a very similar task in Java and it works quite well. A starting point to learn about this can be here:
https://docs.python.org/2/library/re.html
I hope this link will provide a basic foundation in regular expressions

Technical Report Regular Expressions in Java
Using regular expression is your best bet, especially when you don't want too much complications with text processing.
