Answer 1

invalid_chars = ['@'] # Characters you don't want in your text

# Determine if a string has any character you don't want
def if_clean(word):
    for letter in word:
        if letter in invalid_chars:
            return False
    return True

def clean_text(text):
    text = text.split(' ') # Convert text to a list of words
    text_clean = ''
    for word in text:
        if if_clean(word):
            text_clean = text_clean+' '+word
    return text_clean[1:]

# This will print 'abs is good'
print(clean_text('$ascv abs is good'))
