In the past, I used to work with strong-typed languages such as Java so I get a lot of suggestions when working with object / classes.
But when I moved to Python (our team use Python for automation testing), I completely feel lost when I need to know which method does the type/class support.
Recently, I’ve got more time to dig in Python, I got to know Python optional type hints.
So what is optional type hint?
1.Keep in mind that it is optional:
If the variable is not declared with type, that’s totally fine.
2.How to do the type hint:
For example, you create a method that tell Selenium to click on a button.
If you do it without type hint, it will go like this:
def do_not_seed_action(self, driver): do_not_seed_btn = self.downloads_elem.find_do_not_seed_button(driver) do_not_seed_btn.click()
When you write the code, you might not know what can this instance of class/object can do
Should it click() or click_on() or click_in()?
Instead, you can write code with type hint for getting more support from IDE:
from selenium.webdriver.remote.webelement import WebElement do_not_seed_btn: WebElement = self.downloads_elem.find_do_not_seed_button(driver) do_not_seed_btn.click()
And you won’t need to guess what is the right word anymore:
Happy coding ~~~
