   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "BBB"))).click()
   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "CCC"))).click()
if driver.find_element_by_xpath('AAA') == True:
   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "CCC"))).click()

How can i do this?

1. When I can't see AAA, I should click BBB button.
2. When I can see AAA, I must not to click BBB button.
3. When I can see AAA + click BBB button, I can't see AAA.

Answer 1

 elem = driver.find_elements_by_xpath('AAA')
 if not len(elem): 

     WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "BBB"))).click() 
     WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "CCC"))).click()

 else:

     WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "CCC"))).click()

find element doesn't return true or false , use find_elements intead and check the length . if length is not zero then element exists. so not len(elem) checks it doesn't exist meaning false
