Complete the code to open a browser using Selenium WebDriver.

Selenium Python

from selenium import webdriver

driver = webdriver.[1]()
driver.get('https://example.com')
driver.quit()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using lowercase browser names like 'chrome' instead of 'Chrome'.

Forgetting to call the browser constructor as a function.

The webdriver.Chrome() command opens a Chrome browser instance. Selenium supports multiple browsers, but Chrome is commonly used.

Complete the code to find an element by its ID.

Selenium Python

from selenium.webdriver.common.by import By

element = driver.find_element(By.[1], 'submit-button')

Drag options to blanks, or click blank then click option'

ATAG_NAME

BNAME

CCLASS_NAME

DID

💡 Hint

Common Mistakes

Using 'NAME' when the element's ID is needed.

Using string literals instead of By constants.

To find an element by its ID attribute, use By.ID. This is the most direct way to locate elements with unique IDs.

3fill in blank

hard

Fix the error in the code to click a button after waiting for it to be clickable.

Selenium Python

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

wait = WebDriverWait(driver, 10)
button = wait.until(EC.[1]((By.ID, 'submit-button')))
button.click()

Drag options to blanks, or click blank then click option'

Aelement_to_be_clickable

Bpresence_of_element_located

Cvisibility_of_element_located

Dalert_is_present

Attempts:

3 left

💡 Hint

Common Mistakes

Using presence_of_element_located which does not guarantee clickability.

Using alert_is_present which waits for alerts, not elements.

The element_to_be_clickable condition waits until the element is visible and enabled so it can be clicked safely.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps element texts to their IDs for all buttons.

Selenium Python

buttons = driver.find_elements(By.TAG_NAME, 'button')
text_id_map = {btn.text: btn.get_attribute([1]) for btn in buttons if btn.text [2] ''}

Drag options to blanks, or click blank then click option'

A'id'

B!=

C==

D'class'

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'class' instead of 'id' for the attribute.

Using '==' instead of '!=' which would select empty texts.

The code gets the 'id' attribute of each button and includes only buttons with non-empty text (using '!=' '').

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase button texts to their IDs if the ID starts with 'btn'.

Selenium Python

buttons = driver.find_elements(By.TAG_NAME, 'button')
result = {btn.text.[1](): btn.get_attribute([2]) for btn in buttons if btn.get_attribute([3]).startswith('btn')}

Drag options to blanks, or click blank then click option'

Aupper

B'id'

Dlower

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'lower' instead of 'upper' for text conversion.

Using different attributes for get_attribute calls.

The code converts button text to uppercase, gets the 'id' attribute, and filters buttons whose ID starts with 'btn'.
