CodePudding user response：

The Expand all button is in an Iframe. Need to Switch to iframe to perform click operation. And better to apply some waits:

# Imports Required:
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

driver.get("https://etherscan.io/token/0x2b591e99afe9f32eaa6214f7b7629768c40eeb39#readContract")

wait = WebDriverWait(driver,30)

frame = wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID,"readcontractiframe")))

expandall = wait.until(EC.element_to_be_clickable((By.XPATH,"//a[@onclick='expandCollapseAll()']")))
expandall.click()
