selenium cannot send keys to input box

I'm trying to login with seleinum automatically. I've used
driver.execute_script
driver.find_element_by_css_selector
driver.find_element_by_xpath
.
from selenium import webdriver
from webdriver_manager import chrome
driver = webdriver.Chrome(chrome.ChromeDriverManager().install())
driver.get("https://naco999.com/")
driver.find_element_by_css_selector('#login_id').send_keys("id")
driver.find_element_by_css_selector("#login_pw").send_keys("pw")
But none of these seems to work. How can I?

There are 3 elements matching #login_id css_selector.
Try using this:
driver.find_element_by_css_selector(".header-one #login_id").send_keys("id")
driver.find_element_by_css_selector(".header-one #login_pw").send_keys("pw")
Also, you should add a wait to send the text when the elements are loaded.
Like this:
from selenium import webdriver
from webdriver_manager import chrome
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome(chrome.ChromeDriverManager().install())
wait = WebDriverWait(driver, 20)
driver.get("https://naco999.com/")
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".header-one #login_id"))).send_keys("id")
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".header-one #login_pw"))).send_keys("pw")

Selenium not printing inner text of div

I am using selenium to try to scrape data from a website (https://www.mergentarchives.com/), and I am attempting to get the innerText from this element:
<div class="x-paging-info" id="ext-gen200">Displaying reports 1 - 15 of 15</div>
This is my code so far:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait
driver = webdriver.Firefox()
driver.maximize_window()
search_url = 'https://www.mergentarchives.com/search.php'
driver.get(search_url)
assert 'Mergent' in driver.title
company_name_input = '//*[#id="ext-comp-1009"]'
search_button = '//*[#id="ext-gen287"]'
driver.implicitly_wait(10)
driver.find_element_by_xpath(company_name_input).send_keys('3com corp')
driver.find_element_by_xpath(search_button).click()
driver.implicitly_wait(20)
print(driver.find_element_by_css_selector('#ext-gen200').text)
basically I am just filling out a search form, which works, and its taking me to a search results page, where the number of results is listed in a div element. When I attempt to print the text of this element, I simply get a blank space, there is nothing written and no error.

What am I doing wrong?

I think you may need explicit Wait :
wait = WebDriverWait(driver, 10)
info = wait.until(EC.visibility_of_element_located((By.XPATH, "//div[#class = 'x-paging-info' and #id='ext-gen200']"))).get_attribute('innerHTML')
print(info)
Imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

You may need to put a condition by verifying if search results loaded or not and once its loaded you can use below code
print(driver.find_element_by_id('ext-gen200').text)

Trouble parsing some text from a webpage

I've written a script in python using selenium to scrape some text out of a webpage. The text I wanna scrape generates upon filling in an inputbox. My script can fill in in the right way and can populate the value. However, it can't parse the text. How can I do it?
This is what I've tried so far:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome()
wait = WebDriverWait(driver, 10)
driver.get("http://dev.delshlearning.com.au/test.php")
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR,"#AM"))).send_keys("`(2(3^5-sqrt(3)))/2`",Keys.RETURN)
item = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR,"#MQ"))).text
print(item)
driver.quit()
The send_keys() parameter is already filled in within the script for your consideration.

It is storing the text values in the attribute value. This should work:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome()
wait = WebDriverWait(driver, 10)
driver.get("http://dev.delshlearning.com.au/test.php")
# I changed your locater to ID since it's a little more clear
wait.until(EC.visibility_of_element_located((By.ID,"AM"))).send_keys("`(2(3^5-sqrt(3)))/2`",Keys.RETURN)
item = wait.until(EC.visibility_of_element_located((By.ID,"MQ"))).get_attribute('value')
print(item)
driver.quit()
I found it by going to the element's properties as shown highlighted here:

NoSuchElementException: Message: Unable to locate element: p

I am new to selenium, I tried using implicit wait condition and wait until but it is of no use.But it is working fine when it is executed individually.
from selenium import webdriver
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
browser=webdriver.Firefox()
browser.get('https://runningstatus.in')
i=0
element = WebDriverWait(browser, 10)
select=Select(browser.find_element_by_id('godate'))
select.select_by_index(i)
browser.find_element_by_tag_name('input').send_keys('12801',Keys.RETURN)
x=browser.find_element_by_css_selector('div.runningstatus-widget-content')
name=x.find_element_by_tag_name('p')
print name.text

Any time a page transition occurs, or a new element is expected to appear, you should wait for it to exist in the DOM. If you don't, you'll get frequent timeouts. In your case, try the following...
from selenium import webdriver
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
browser=webdriver.Firefox()
browser.get('https://runningstatus.in')
i=0
element = WebDriverWait(browser, 10)
select=Select(browser.find_element_by_id('godate'))
select.select_by_index(i)
browser.find_element_by_tag_name('input').send_keys('12801',Keys.RETURN)
css = 'div.runningstatus-widget-content'
x = WebDriverWait(browser, 30).until(
EC.element_to_be_clickable(('css selector', css)))
print x.text

Selenium Python Script throws no element error exception even though the x path is right?

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.keys import Keys
driver=webdriver.Chrome()
driver.get("https://paytm.com/")
driver.maximize_window()
driver.find_element_by_class_name("login").click()
driver.implicitly_wait(10)
driver.find_element_by_xpath("//md-input-container[#class='md-default-theme md-input-invalid']/input[#id='input_0']").send_keys("99991221212")
In the above code, I have verified the xpath using fire bug its highlighting the correct element. But when the script run its failing? Can you help me folks?

In selenium each frame is treated individually. Since the login is in a separate iframe element, you need to switch to it first using:
iframe = driver.find_elements_by_tag_name('iframe')[0]
driver.switch_to_frame(iframe)
Before trying to interact with it's elements.
Or in this case, you would wait for the frame to exist, and it would be:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome()
driver.get("https://paytm.com/")
driver.maximize_window()
wait = WebDriverWait(driver, 10)
wait.until(EC.visibility_of_element_located((By.CLASS_NAME, "login"))).click()
wait.until(EC.frame_to_be_available_and_switch_to_it((By.TAG_NAME, "iframe")))
_input = wait.until(EC.visibility_of_element_located((By.ID,"input_0")))
_input.send_keys("99991221212")

You should try using WebDriverWait to wait until input element visible on the page as below :-
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome()
driver.get("https://paytm.com/")
driver.maximize_window()
wait = WebDriverWait(driver, 10)
wait.until(EC.visibility_of_element_located((By.CLASS_NAME, "login"))).click()
#now switch to iframe first
wait.until(EC.frame_to_be_available_and_switch_to_it((By.TAG_NAME, "iframe")))
input = wait.until(EC.visibility_of_element_located((By.ID, "input_0")))
input.send_keys("99991221212")
Hope it helps...:)
