I defined a function and apply it to a column in Pandas. But it does not return correct values.
I am trying to test which url in a column full of url to see which one can be connected to or not def connect(url): try: urllib.request.urlopen(url) return True except: return False df['URL'] = df.apply(lambda x: connect(df['URL']), axis=1) I ran without any error, but did not return any true. I just could not find any error with it. Can anyone try and find out why Regards, David -- https://mail.python.org/mailman/listinfo/python-list
