How to input letters in capital letters in an edit box in Selenium with python?

We can input letters in capital letters in an edit box in Selenium with the
help of Action Chains class. These classes are generally used for automating
interactions like context menu click, mouse button actions, key press and mouse
movements.
These types of actions are mainly common in complex scenarios like drag and drop
and hovering over an element on the page. The methods of the Action Chains class
are utilized by advanced scripts. We can manipulate DOM with the help of Action
Chains in Selenium.
The action chain object implements the ActionChains in the form of a queue and
then executes the perform() method. On calling the method perform(), all the
actions on action chains will be performed.
The method of creating an Action Chain object is listed below −
First we need to import the Action Chain class and then the driver will be
passed as an argument to it.

Now all the operations of action chains can be done with the help of this

Syntax for creating an object of Action Chains −
from selenium import webdriver
# import Action chains
from selenium.webdriver import ActionChains
# create webdriver object
driver = webdriver.Firefox()
# create action chain object
action = ActionChains(driver)
After creating an object of Action Chains, we can perform numerous operations
one by one like a chain which is queued.
In order to enter letters in upper case in the edit box, we need to first move to the
edit box, then perform click() action. Then press SHIFT and enter the letters using
send_keys() method. Finally use perform() to execute all these queued operations.
#element
source = driver.find_element_by_id("name")
#action chain object
action = ActionChains(driver)
# move the mouse to the element
action.move_to_element(source)
# perform click operation on the edit box
action.click()
# perform clicking on SHIFT button
action.key_down(Keys.SHIFT)
# input letters in the edit box
action.send_keys('tutorialspoint')
# perform the queued operation
action.perform()
Code Implementation for inputting letters in upper case.
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys
#browser exposes an executable file
#Through Selenium test we will invoke the executable file which will then
#invoke actual browser
driver = webdriver.Chrome(executable_path="C:\\chromedriver.exe")
# to maximize the browser window
driver.maximize_window()
#get method to launch the URL
driver.get("https://www.tutorialspoint.com/index.htm")
#to refresh the browser
driver.refresh()
# identifying the source element
source= driver.find_element_by_xpath("//input[@name='search']");
# action chain object creation
action = ActionChains(driver)
# move the mouse to the element
action.move_to_element(source)
# perform click operation on the edit box
action.click()
# perform clicking on SHIFT button
action.key_down(Keys.SHIFT)
# input letters in the edit box
action.send_keys('tutorialspoint')
# perform the queued operation
action.perform()
#to close the browser
driver.close()
