The form may not be visible on the website because it is being loaded dynamically through JavaScript or AJAX after the initial page load. In such cases, when you send a request using the `requests` library, it only fetches the initial server response, which may not include the dynamically loaded content.
To overcome this issue, you can try using a library like Selenium which allows you to automate browser actions, including interacting with dynamically loaded content. This way, you can emulate a browser session and ensure that the form is visible before submitting your request.
Here's an example of how you can use Selenium to interact with the dynamically loaded form:
```python
from selenium import webdriver
# Create a new instance of the Chrome driver
driver = webdriver.Chrome()
# Load the page
driver.get('https://snaptik.mom/')
# Find the form input field and set its value
url_input = driver.find_element_by_name('url')
url_input.send_keys('https://www.tiktok.com/@lisaandlena/video/6926975884846992645')
# Submit the form
form = driver.find_element_by_tag_name('form')
form.submit()
# Wait for the response page to load
driver.implicitly_wait(10)
# Get the response content
response_content = driver.page_source
# Print the response content
print(response_content)
# Close the browser
driver.quit()
```
By using Selenium, you can ensure that the form is visible and submit it effectively to receive the desired response.
