Let's break down why your script is failing and fix it step by step:

1. The Root Cause of the 'list' object has no attribute 'click()' Error #

You used find_elements_by_xpath (note the plural "elements") which returns a list of web elements, not a single element. You can't call click() on a list—you need to target the specific like button element with find_element_by_xpath (singular "element").

2. Fixing the Logic Flow #

Your like button code was placed outside the like function's loop, so it never ran for each post you navigated to. We need to move that code inside the loop where you visit each post URL.

3. Updating Deprecated Selenium Methods #

The old find_element_by_xpath style methods are deprecated in newer Selenium versions. It's better to use the modern By class syntax for better compatibility.

4. Adjusting Element Locators (Instagram's UI Might Change) #

Your original XPATH for the like button might be brittle. A more reliable locator would target the button by its aria-label or class, since Instagram's DOM structure can update without warning.

# Execute the script
login("your_username_here", "your_password_here")
like('hacking')

# Don't forget to close the driver when done
driver.quit()

Additional Notes to Avoid Instagram Restrictions #

• Add reasonable delays: Instagram detects automation easily, so use moderate time.sleep() values (don't make them too short).
• Limit actions: Don't like hundreds of posts in a row—Instagram might flag or restrict your account.
• Use try-except blocks: This prevents your script from crashing if a UI element doesn't load or the page structure changes.
