[FIXED] How to replace part of string with python pandas?

Issue

I'm having a problem replacing a part of the string in Pandas.

I have a list of links of a website like this (for example):

https://stackoverflow.com/questions
https://stackoverflow.com/some_page
https://stackoverflow.com/about

and I would like to replace https://stackoverflow.com/ with link/.

And it should be like this:

link/questions
link/some_page
link/about

I tried something like this but it replaces the whole string:

df.loc[df['links'].str.contains('https://stackoverflow.com/'), 'links'] = 'link/'

links is the name of column

How do I do this?

Thanks in advance.

Solution

This should get you what you need as long as the URLs are consistent.

data = {
    'Column1' : ['https://stackoverflow.com/questions', 'https://stackoverflow.com/another', 'https://stackoverflow.com/last']
}

df = pd.DataFrame(data)
df['Column1'] = df['Column1'].apply(lambda x : 'Link/' + x.split('/')[-1])
df
