Stop using the string when there is a special character

I have a text file file1.txt. I have already performed preprocessing (cleaning) on it. Operations like replace("-","") etc. Now I want to perform few more operations on the clean text string. How can I check if the string is cleaned or not i.e without any special characters like @!#$%^ etc.? If not cleaned it should print invalid entry? Can I do it without using re?

def process():
 with open("file1.txt",'r') as a:
            text = a.read #toconvert into string
            for ch in ['_','-']:
                 text = text.replace(ch,"")
            return text
process()

Without using regex, you can do this:

special_char = '@!#$%^' # maybe string.punctuation?
text ='I love pizza and chips@'

print("Invalid") if any(c in special_char for c in text) else print("Valid")

To answer your second question, you should write in your case:

ch = '@#$%^&*' 

with open(cleanfile, 'r') as s: 
    s = s.readlines()
    if any(c in ch for c in s):
        print('Invalid')
    else:
        li = s.split()
