Chick if object exists.

[scidam]

So, does anyone know how can I check if that object exists before try to use it?

You can wrap your code into try/except clause, e.g.

from selenium.common.exceptions import NoSuchElementException
# ... 
try:
    nav.find_element_by_xpath('/html/body/div[1]/div/div[3]/div[1]/div/div[2]/div/div/span[1]/p[1]')
except NoSuchElementException:
    pass # or do something
