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
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
