You have a CSV file with email addresses. You want to return only the email address -- not lines that have an email address. What do you do?
Assuming the email addresses are in a file named email.txt, use this Python 3 program:
with open('email.txt', 'r') as a: for b in a: if '@' in b: #operate only on lines with "@" c = b.split() #split up words on line for d in c: #iterate through characters of words if '@' in d: #if email address, print(d+';') #print email address
