Python TypeError: Required argument 'source' (pos 1) not found
I get an error: TypeError: Required argument 'source' (pos 1) not found
but I haven't got a clue what it means :/. Can anyone put me on the right track?
My code is:
def openFile(self,fileName):
email_pattern = re.compile(r'\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b', re.IGNORECASE)
with open(fileName) as lijstEmails:
self.FinalMailsArray.append([email_pattern.findall() for line in lijstEmails])
self.writeToDB()
Basical开发者_StackOverflowly it opens a number files in a directory, reads them and then goes looking for email addresses and writes them to a database.
email_pattern.findall()
requires an argument to be passed. So your code should be this -
with open(fileName) as lijstEmails:
self.FinalMailsArray.append([email_pattern.findall(line) for line in lijstEmails])
Note that email_pattern.findall()
returns a list, so what you will be making will be list of list in the end. If you are sure that every line contains at the most 1 email_address then you can use -
with open(fileName) as lijstEmails:
self.FinalMailsArray.append([email_pattern.findall(line)[0] for line in lijstEmails])
