Attribute Error: 'str' object has no attribute 'str'

Question

I have a dataframe column which contains URLs. I want to extract a specific string out of this URL by using a regex pattern for each row. Here is an example of the URL string:

'www.abcdef.com/sports-bra-sports-bra-black-abcde1f02-c11.html',

As a column is a series and I need to iterate through, I've tried the following codes:

1.

for i in df['landing_screen_name']:
    regex = i.str.extract(r'.{0,13}.html')
    print(regex)
    break

2.

for idx, row in df.iterrows():
    a = row['landing_screen_name'].str.contains(r'.{0,13}.html')
    print(a)
    break

however for both I got the following error:

AttributeError: 'str' object has no attribute 'str'

I've tried everything but couldn't find the issue yet, could you please help me with this?

Answer 1

Try this:

df['landing_screen_name'] = df['landing_screen_name'].str.extract(r'(.{0,13}\.html)')

Answer 2

You should operate at the column level, eg use:

print(df['landing_screen_name'].str.extract(r'.{0,13}.html').to_string(index=False))
