How to remowe a string up to a specific character (Python/pandas)?-CodePudding

I have the DataFrame:

link = [{'name': 'http://website.com/product76tre53932'}, {'name': 'http://website.it/productiee8340'}, {'name': 'http://website.de/productooi7309'}]
df = pd.DataFrame(link)

How I can cut values that get the next result, which you can see in the df['name_2] column: enter image description here

CodePudding user response：

You can use urllib.parse module to parse those URLs.

>>> from urllib.parse import urlsplit
>>>
>>> def create_url(url):
...     r = urlsplit(url)
...     return f"{r.scheme}://{r.netloc}"
...
>>> link = [{'name': 'http://website.com/product76tre53932'}, {'name': 'http://website.it/productiee8340'}, {'name': 'http://website.de/productooi7309'}]
>>>
>>> import pandas as pd
>>> df = pd.DataFrame(link)
>>> df['new_url'] = df.name.apply(create_url)
>>> df
                                   name             new_url
0  http://website.com/product76tre53932  http://website.com
