Selenium syntax difference on different resources - Why is this

I have been working with selenium and consulting different helping resources for error solving. I have seen that sometimes, there is a slight difference in the syntax of the locators used.

This is what I am currently using.

driver.find_element(By.ID, "id")

But I have also seen this being used sometimes:

driver.find_element_by_id("id")

Can you please explain the difference.

I am using the following syntax but curios why is there a different syntax as well.

driver.find_element(By.ID, "id")
