Remove part of string within a loop in python

Keep in mind this in within a loop.

How can I remove everything from "?" and so on?

So that "something_else_1" gets deleted

Url_before = "https:www.something.com?something_else_1"


Url_wanted = "https:www.something.com?"

In practice it looks kinda like this:

find_href = driver.find_elements(By.CSS_SELECTOR, 'img.MosaicAsset-module__thumb___yvFP5')

with open("URLS/text_urls.txt", "a+") as textFile:
            for my_href in find_href:
                textFile.write(str(my_href.get_attribute("src"))+"#do_something_to_remove_part_after_?_in_find_href"+"\n")

>Solution :

Provided there’s only one instance of "?" in the string and you want to remove everything after it, you could find the index of this character with

i = Url_before.index("?")

and then remove everything after it:

Url_wanted = Url_before[:i+1]
