My current code doesn't switch from one profile to other

from DrissionPage import ChromiumOptions, ChromiumPage,Chromium
co = ChromiumOptions()
co.set_user(user='event_name1')
page = ChromiumPage(co)
co = ChromiumOptions()
co.set_user(user='event_name2')
page = ChromiumPage(co)

My current code doesn't switch from one profile to other

page = ChromiumPage(co)

page = ChromiumPage(co)

• python
• chromium

• You would need to give the actual name of profile, what i mean is suppose you created a profile in chrome (Profile 2). Now if you try to switch to this profile using this co.set_user("Profile 2"), drission wont switch to this profile because under the hood it is looking for a unique identifier of this profile, if it cant find then drission will create a new profile. But if you want to switch back to default profile which is named as Profile 1. Then you would have to switch like this co.set_user("Default"). Then only drission will know ok i have to switch to Profile 1. – Aniket Commented Nov 19, 2024 at 7:23
• @Aniket Thanks for your answer, I tried this thing multiple times but it does not work. The issue is that Chromium targets a port for opening a browser and if we do not provide a port to it then it will open the browser at its default port so if we have to open multiple instances at a time then for each instance we have to provide different port name or call a auto port for various number of instances – Osama Bin Ghazanfar Commented Nov 20, 2024 at 8:13
• I understand but your question was how can you switch multiple chrome profiles by their names!! So i tried to help you based on that only but nevertheless it worked so its fine!! – Aniket Commented Nov 21, 2024 at 16:27
