The input element and button elements are different, so you can't click with Python Selenium

<div class="add_area">
				<input type="file" name="files[]" title=file add" class="file_add" multiple="">
				<button type="button" class="btn_add"><em class="sp_img icon_add "></em>file add</button>
			</div>

I’m trying to click a button with Python Selenium, but the button element and input element are located differently, so I can’t click. Please find a solution.
