Taking action on a webpage(select checkbox or enter textbox or select from a list)
Multiple things should be fixed:


Stylistic/Code Style issues:


consistent indentation - per PEP8, use 4 spaces
follow the variable naming guidelines (PEP8 reference) - in particular, fix the "camel case" names and add underscores between the words in your variable names in upper case  
truthiness checks can be simplified, e.g. if checkboxUncheck instead of checkboxUncheck == True
do not use bare except clause - it really makes things less understandable - catch specific exception and let it fail in all other situations 

Selenium specific issues:


your XPath expressions are quite fragile - you are going up and down the tree relying on the depth level and HTML markup too much. Think about using meaningful data-oriented id, class or other attributes to get to the desired elements. And, XPaths are generally less readable and more error-prompt. There are many other location techniques.
clicking elements via JavaScript might lead to problems, see if you can use regular click() method (WebDriver click() vs JavaScript click())
you may benefit from a "Page Element" page object abstraction
I think you should not actually need the "action chains" here:

actions = webdriver.ActionChains(self.driver)
actions.move_to_element(elemtwo)
elemtwo.clear()
actions.send_keys(enterValue)
actions.perform()


and can replace it with just:

elemtwo.clear()
elemtwo.send_keys(enterValue)




Code review and refactoring is a continuous process - if you would apply all the suggested fixes, I bet we'll see more things to improve.
