Situation: You’re doing automated data-collection using
Selenium’s Python Client Driver
but can’t find any documentation online on the Select
class. What now?
If the developers included docstrings in the class, we’re in luck!
Python’s help
function shows any source documentation of the object or class
passed to it.
>>> select_element = Select(driver.find_element_by_tag_name('select'))
>>> help(select_element)
Help on instance of Select in module selenium.webdriver.support.select:
class Select
| Methods defined here:
|
| __init__(self, webelement)
| Constructor. A check is made that the given element is, indeed, a SELECT tag.
| If it is not, then an UnexpectedTagNameException is thrown.
|
| :Args:
| - webelement - element SELECT element to wrap
|
| Example:
| from selenium.webdriver.support.ui import Select
|
| Select(driver.find_element_by_tag_name("select")).select_by_index(2)
|
| deselect_all(self)
| Clear all selected entries.
| This is only valid when the SELECT supports multiple selections.
| throws NotImplementedError If the SELECT does not support multiple selections
|
:
Lucky me, the Select
class contains detailed docstrings.
And if you want to see all the method names, you can use dir(object)
.
>>> dir(select_element)
['__doc__', '__init__', ..., 'select_by_value', 'select_by_visible_text']
