Form Input Value automatically resets when executing query with Python Selenium-CodePudding

I am trying to set input field of a Modal Form using Python's Selenium

Here's how the form's input looks like :

<input step="any" class="input" placeholder="0" value="">

I set the input value with this script:

script = "document.querySelector("input.input").value='1'"
driver.execute_script(script)
time.sleep(3)

My script does enter input value in the field but it remains there only for 3 Seconds and that too due time.sleep(3) , otherwise it resets instantly to 0.

How can I set it to remain there and not to reset?

When I try normally on a HTML page, it does not resets. It does so only on that web page.

Kindly help

The following code works fine.

# changed it from 'input.input' -> '.input'
script = "document.querySelector('.input').value='1'"

driver.execute_script(script)
time.sleep(3)

Also, use single inverted commas ' to catch the element class because you are using double inverted commas " to declare the script for your script variable.

When trying to catch elements by their class name to execute queries:

script = "document.querySelector('.class_name').value='1'"

When trying to catch elements by their ID to execute queries:

script = "document.querySelector('#ID').value='1'"

Alternatively, you can use the send_keys method too:

# entering the xpath of the text box you want to send your keys to
driver.find_element_by_xpath("//*[@id='body']/div[8]/div/div/div/div[2]/div[1]/div[2]/div[2]/div[3]/input").send_keys("1")

elem=wait.until(EC.element_to_be_clickable((By.CLASS_NAME,"input")))                   
elem.send_keys('1')

Send keys didn't change back after a few seconds.
