How to find and write inside an input tag with selenium python

Question

I would like to change a value of a input tag that haves the value 20 to 110 in the website https://www.tradingview.com/chart/. How can I actually do that?(all of that using selenium python) The value i would like to change it's MA Length inside Vol, you can acess that by clicking at Vol(20) right below Apple Inc - D - Cboe BZX at the top left part of the website.

Clicking Vol(20) doesn't brings up the popup. Any further steps involved? Possibly you need a set of valid credentials. Do you have a demo set? — undetected Selenium

Locate the element you would like to interact with using your favourite browser developer tools
Choose an appropriate Locator Strategy which will allow to uniquely match the element at the page
Locate the element
Wrap the locating code into an Explicit Wait this way your test will be more robust and reliable
Use WebElement APIs to interact with elements

Example code:

driver.get("https://www.tradingview.com/chart/")

WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//a[contains(@class,'format')]"))).click()
input = WebDriverWait(driver, 10).until(
    EC.element_to_be_clickable((By.XPATH, "//input[contains(@class,'innerInput')]")))
driver.execute_script("arguments[0].value=30", input)
