Im passing through some urls and I’d like to strip a part of it which dynamically changes so I don’t know it firsthand.
An example url is:
https://...?pid=2&gid=lostchapter&lang=en_GB&practice=1&channel=desktop&demo=2
And I’d like to strip the gid=lostchapter part without any of the rest.
How do I do that?
>Solution :
You can use urllib to convert the query string into a Python dict and access the desired item:
In [1]: from urllib import parse
In [2]: s = "https://...?pid=2&gid=lostchapter&lang=en_GB&practice=1&channel=desktop&demo=2"
In [3]: q = parse.parse_qs(parse.urlsplit(s).query)
In [4]: q
Out[4]:
{'pid': ['2'],
'gid': ['lostchapter'],
'lang': ['en_GB'],
'practice': ['1'],
'channel': ['desktop'],
'demo': ['2']}
In [5]: q["gid"]
Out[5]: ['lostchapter']
