How to find element by part of its id name in selenium with python

Question

I'm using selenium with python,now I want to locate an element by part of its id name,what can I do?

For example,now I've already located a item by id name coption5 :

sixth_item = driver.find_element_by_id("coption5")

Is there anyway I can locate this element only by using coption?

Use XPATH's "contains" method: https://www.guru99.com/xpath-selenium.html#6 — pcalkins, Jan 07 '20 at 22:44
@Guy This question is all about locators _Xpath_ and _Css_, any reason why you want to hide the question from _Xpath_ and _Css_ contributors removing those tags? — DebanjanB, Jan 08 '20 at 06:45
@DebanjanB Using xpath and css_selector is the solution, not the question. — Guy, Jan 08 '20 at 07:20
@Guy So what do you feel the question was all about :) Does Selenium have any other way other then _Css_ and _Xpath_ — DebanjanB, Jan 08 '20 at 07:23
@DebanjanB yes, it has https://selenium-python.readthedocs.io/locating-elements.html — Guy, Jan 08 '20 at 07:26
@Guy I'm sorry, I'm not getting your logic here. Anyway, please try to assist the _New contributors_ rather then reducing the visibility of the questions asked. — DebanjanB, Jan 08 '20 at 07:32

To find the element which you have located with:

sixth_item = driver.find_element_by_id("coption5")

To locate this element only by using coption you can use can use either of the following Locator Strategies:

Using XPATH and starts-with():

sixth_item = driver.find_element_by_xpath("//*[starts-with(@id, 'coption')]")

Using XPATH and contains():

sixth_item = driver.find_element_by_xpath("//*[contains(@id, 'coption')]")

Using CSS_SELECTOR and ^ (wildcard of starts-with):

sixth_item = driver.find_element_by_css_selector("[id^='coption']")

Using CSS_SELECTOR and * (wildcard of contains):

sixth_item = driver.find_element_by_css_selector("[id*='coption']")
