Selenium Python - Handling No such element exception

I am writing automation test in Selenium using Python. One element may or may not be present. I am trying to handle it with below code, it works when element is present. But script fails when element is not present, I want to continue to next statement if element is not present.

try:
       elem = driver.find_element_by_xpath(".//*[@id='SORM_TB_ACTION0']")
       elem.click()
except nosuchelementexception:
       pass

Error -

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element:{"method":"xpath","selector":".//*[@id='SORM_TB_ACTION0']"}
