How to clear a text edit field? android python appium

how to clear text edit field? android python appium? I tried that way:

el = driver.find_element_by_id(‘text edit field id’).clear()
el.click()
el.clear()
however, it actually deletes only one symbol.

I think may by call an el.click() twice and send keycode to delete highlighted text area but how to highlight the text?
