Find element by tag name in Selenium Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ locator

intermediate

Locate the first

Which Selenium Python code snippet correctly finds the first

A element = driver.find_element(By.ID, 'button')

B element = driver.find_element_by_tag('button')

C element = driver.find_element(By.CLASS_NAME, 'button')

D element = driver.find_element(By.TAG_NAME, 'button')

💡 Hint

Use the correct Selenium method and locator strategy for tag name.

The correct method to find an element by tag name in Selenium Python is find_element with By.TAG_NAME and the tag name string.

❓ assertion

intermediate

Assert the text of the first

Given the code below, which assertion correctly checks that the first

element's text is exactly 'Welcome'?

Selenium Python

element = driver.find_element(By.TAG_NAME, 'h1')
text = element.text

A assert text.contains('Welcome')

B assert text == 'Welcome'

C assert text.equals('Welcome')

D assert text is 'Welcome'

💡 Hint

Use Python string equality to check exact match.

In Python, to check exact string equality, use '==' operator. Methods like contains or equals do not exist on strings.

❓ Predict Output

Output of finding multiple elements by tag name

What is the output of the following code snippet if the page contains exactly 3

elements?

Selenium Python

elements = driver.find_elements(By.TAG_NAME, 'li')
print(len(elements))

A 3

B 1

C 0

D TypeError

💡 Hint

find_elements returns a list of matching elements.

find_elements returns a list of all matching elements. len() returns the count. Since there are 3

elements, output is 3.

🔧 Debug

advanced

Identify the error in finding element by tag name

What error will the following code raise if no

element exists on the page?

Selenium Python

element = driver.find_element(By.TAG_NAME, 'footer')

A TypeError

B AttributeError

C selenium.common.exceptions.NoSuchElementException

D IndexError

💡 Hint

find_element raises an exception if no element is found.

If find_element does not find any matching element, it raises NoSuchElementException in Selenium.

Best practice for waiting for an element by tag name

Which Selenium Python code snippet correctly waits up to 10 seconds for the first

element to be present before continuing?

A element = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.TAG_NAME, 'nav')))

B

driver.implicitly_wait(10)
element = driver.find_element(By.TAG_NAME, 'nav')

C element = driver.find_element(By.TAG_NAME, 'nav')

D

time.sleep(10)
element = driver.find_element(By.TAG_NAME, 'nav')

💡 Hint

Use explicit waits with expected conditions for reliable waiting.

Explicit wait with WebDriverWait and expected_conditions waits up to the timeout for the element to appear, avoiding unnecessary delays or errors.

Practice

1. What does find_element(By.TAG_NAME, 'button') do in Selenium Python?

easy

A. Finds all <button> elements on the page

B. Finds elements by their ID 'button'

C. Finds elements by their class name 'button'

D. Finds the first <button> element on the page

Solution

1. Step 1: Understand the method used

   The method find_element returns the first matching element found.

2. Step 2: Understand the locator type

   Using By.TAG_NAME with 'button' searches for the first <button> tag element.

3. Final Answer:

   Finds the first <button> element on the page -> Option D

4. Quick Check:

   find_element + TAG_NAME = first matching tag element [OK]

Hint: find_element + TAG_NAME finds only the first matching tag [OK]

Common Mistakes:

• Confusing find_element with find_elements
• Using class name or ID instead of tag name
• Expecting all elements instead of first only

2. Which of the following is the correct syntax to find all p elements using Selenium Python?

easy

A. driver.find_element_by_tag_name('p')

B. driver.find_element(By.TAG_NAME, 'p')

C. driver.find_elements(By.TAG_NAME, 'p')

D. driver.find_elements_by_class_name('p')

Solution

1. Step 1: Identify method for multiple elements

   To get all matching elements, use find_elements (plural).

2. Step 2: Use correct locator for tag name

   Use By.TAG_NAME with the tag string 'p'.

3. Final Answer:

   driver.find_elements(By.TAG_NAME, 'p') -> Option C

4. Quick Check:

   find_elements + TAG_NAME = all matching tags [OK]

Hint: Use find_elements (plural) to get all elements by tag [OK]

Common Mistakes:

• Using find_element instead of find_elements
• Using deprecated find_element_by_tag_name syntax
• Confusing class name locator with tag name

3. Given the HTML:

<div>
  <button>Click</button>
  <button>Submit</button>
</div>

What will driver.find_element(By.TAG_NAME, 'button').text return?

medium

A. "ClickSubmit"

B. "Click"

C. "Submit"

D. Throws NoSuchElementException

Solution

1. Step 1: Understand find_element behavior

   It returns the first matching element by tag name, which is the first <button> with text "Click".

2. Step 2: Access the text property

   The .text attribute returns the visible text inside that element, which is "Click".

3. Final Answer:

   "Click" -> Option B

4. Quick Check:

   First button text = "Click" [OK]

Hint: find_element returns first tag; .text shows its text content [OK]

Common Mistakes:

• Assuming it returns all buttons' text combined
• Confusing find_element with find_elements
• Expecting an exception when element exists

4. You wrote this code:

element = driver.find_elements(By.TAG_NAME, 'img')

But you get an error when trying element.click(). What is the problem?

medium

A. find_elements returns a list, not a single element

B. The tag name 'img' is invalid

C. click() cannot be used on images

D. You must use find_element instead of find_elements

Solution

1. Step 1: Understand return type of find_elements

   find_elements returns a list of WebElements, not a single element.

2. Step 2: Identify why click() fails

   Calling click() on a list causes an error because lists don't have click method.

3. Final Answer:

   find_elements returns a list, not a single element -> Option A

4. Quick Check:

   find_elements = list, cannot call click() directly [OK]

Hint: find_elements returns list; call click() on list item, not list [OK]

Common Mistakes:

• Calling click() on list instead of element
• Confusing find_element and find_elements return types
• Assuming all tags support click() without checking

5. You want to click the second button on a page. Which code correctly finds and clicks it using tag name?

hard

A. buttons = driver.find_elements(By.TAG_NAME, 'button')
buttons[1].click()

B. button = driver.find_element(By.TAG_NAME, 'button')
button[1].click()

C. button = driver.find_elements(By.TAG_NAME, 'button')
button.click()

D. buttons = driver.find_element(By.TAG_NAME, 'button')
buttons.click()

Solution

1. Step 1: Use find_elements to get all buttons

   Use find_elements(By.TAG_NAME, 'button') to get a list of all button elements.

2. Step 2: Access second button and click

   Index 1 accesses the second button (0-based index), then call click() on it.

3. Final Answer:

   buttons = driver.find_elements(By.TAG_NAME, 'button') buttons[1].click() -> Option A

4. Quick Check:

   find_elements + index + click = correct usage [OK]

Hint: Use find_elements, index second item, then click [OK]

Common Mistakes:

• Using find_element and indexing it like a list
• Calling click() on list instead of element
• Using wrong index (like 2 instead of 1 for second element)
