Accepted Answer

You can chain your action, so no need to do perform after each action.

```
actions = ActionChains(driver)
actions.move_to_element(nextpage)
actions.click(nextpage)
actions.perform()
```

OR

```
actions = ActionChains(driver)
actions.move_to_element(nextpage)
actions.click(nextpage).perform()
```
