Unable to send WhatsApp message using chrome driver Python Error: NoSuchElementException

This is my first post here!
I am using Selenium's Chrome Driver to send WhatsApp attachment to some people.
Here is my code:
from selenium import webdriver
import os
from time import sleep
link="https://wa.me/91xxxxxxxxxx"
phnno="91xxxxxxxxxx"
driver=webdriver.Chrome(executable_path=f"{os.getcwd()}\\chromedriver.exe")
#driver.get(link)
#button=driver.find_element_by_xpath('//a[#title="Share on WhatsApp"]')
#button.click()
driver.get(f"https://web.whatsapp.com/send?phone={phnno}&text&app_absent=0")
#This above line opens up the sender window in whatsapp
attachbutt=driver.find_element_by_xpath('//span[#data-icon="clip"]') #This is line 15
#The above line is the one that is giving me the error
attachbutt.click()
sleep(10)
forpdf=driver.find_element_by_xpath('//input[#accept="*"]')
path="C:\\Users\\Deven\\Desktop\\test_file.pdf"
forpdf.send_keys(path) #Attaches the file
sleep(5)
sendbutt=driver.find_element_by_xpath('//span[#data-icon="send"]')
sendbutt.click()

It says it is unable to locate the element but I have bene very careful in inspecting the website and then writing the code. Still I wonder why it does not work. Can anyone please help me with what is it that I am doing wrnong? Thank You!

Looks like you are missing a wait / delay before clicking that element.
The simplest solution is to put
sleep(5)
before
attachbutt=driver.find_element_by_xpath('//span[#data-icon="clip"]')
However, it's much better to use expected conditions there. Like this:
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
attachbutt = WebDriverWait(driver, 20).until(
EC.element_to_be_clickable((By.XPATH, '//span[#data-icon="clip"]')))

I want to click on the 480 link, but I can't with the above code
I've attempted other variations where I try and inspect the html block, but I've been unsuccessful.

To click() on the link with text as Magnet for the item One Punch Man S2 you need to click the <a> node within the <span> node and you have to induce WebDriverWait for the element to be clickable and you can use either of the following Locator Strategies:
Using XPATH:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[contains(., 'One Punch Man S2')]//following::span[#class='dl-type hs-magnet-link']/a"))).click()
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

Login script in popup window. No such element

I'm trying to get a login script to select a user name input to enter in my user name. After this popup is done there will be another one asking for the password. I'm new to python and web interfaces so I'm having trouble identifying what element of the website I need to select to get this to work. Here is the code I have so far.
import selenium
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait as wait
DynamoForum = webdriver.Chrome()
DynamoForum.get("https://forum.dynamobim.com/")
login = DynamoForum.find_element_by_class_name("header-buttons").click()
#DynamoForum.switch_to_frame(DynamoForum.find_element_by_
#wait(DynamoForum,10).until(EC.frame_to_be_available_and_switch_to_it(
DynamoForum.find_element_by_xpath("//title[1]")))
wait(DynamoForum,10).until(EC.frame_to_be_available_and_switch_to_it(
DynamoForum.find_element_by_xpath(
"//iframe[#id='destination_publishing_iframe_autodesk_0']")))
DynamoForum.find_element_by_id("userName").send_heys("xxx")
The website is opening and the popup is starting but no text is being entered. Here is what my getting as a result:
Traceback (most recent call last):
File "C:/Users/cjr/PycharmProjects/DynamoForum/DynamoForum.py", line 17, in <module>

Basically when you are clicking on login button, you are moving to another window and to access the element in new window you need to switch it from parent window to access this.Try the below code it should work.
from selenium import webdriver
DynamoForum = webdriver.Chrome()
DynamoForum.get("https://forum.dynamobim.com/")
Parent_window = DynamoForum.window_handles[0]
login = DynamoForum.find_element_by_class_name("header-buttons").click()
window_child= DynamoForum.window_handles[1]
DynamoForum.switch_to.window(window_child)
DynamoForum.find_element_by_id("userName").send_keys("xyz#gmail.com")
DynamoForum.find_element_by_id("verify_user_btn").click()
wait=WebDriverWait(DynamoForum,20)
wait.until(EC.visibility_of_element_located((By.ID,"password"))).send_keys("xxx")
DynamoForum.find_element_by_id("btnSubmit").click()

You need to switch to the iframe.
e.g.
iframe = driver.find_element_by_id('destination_publishing_iframe_autodesk_0')
driver.switch_to.frame(iframe)
driver.find_element_by_name('userName').send_keys('xxx')
See the switch_to function here : https://selenium-python.readthedocs.io/api.html?highlight=iframe
For reference:
python selenium cant find iframe xpath

Exception on execution PhantomJS + Selenium Webdriver + Python program

With all installation prerequisite of PhantomJS and Selenium on my Ubuntu machine I am running below code snippet:
from selenium import webdriver
driver = webdriver.PhantomJS()
driver.set_window_size(1120, 550)
driver.get("https://duckduckgo.com/")
driver.find_element_by_id('search_form_input_homepage').send_keys("realpython")
driver.find_element_by_id("search_button_homepage").click()
print driver.current_url
driver.quit()
On execution I am getting below error:

Setting --ssl-protocol=any service argument and using Explicit Waits made it work for me:
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.PhantomJS(service_args=['--ssl-protocol=any'])
driver.maximize_window()
driver.get("https://duckduckgo.com/")
wait = WebDriverWait(driver, 10)
search = wait.until(EC.presence_of_element_located((By.ID, "search_form_input_homepage")))
search.send_keys("realpython")
driver.find_element_by_id("search_button_homepage").click()
print driver.current_url
driver.quit()
Prints https://duckduckgo.com/?q=realpython.
Note that without --ssl-protocol=any PhantomJS hasn't even loaded the page and the current url stayed as about:blank.

I think whats happening to you is that you try to find an element which is not loaded yet on the page. So what I can recommend is the insert a WaitForElementDisplayed(by.ID("search_form_input_homepage")); right before you try to type in the search field. So you will be sure that the element is there before trying to interact with it.
I can't really give you a code example because I'm not really familiar with the Python bindings.

Getting "Message: h is null"

I've recently encountered something I've never seen before while using selenium.
The code (quite simple and straightforward):
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://www.drugs.com/drug-class/laxatives.html?condition_id=&generic=0&sort=rating&order=desc")
print driver.find_element_by_tag_name("title").text
Here is a stack trace of the error I'm getting:
Traceback (most recent call last):
File "/Users/a/p/SO/selenium_scripts/test.py", line 6, in <module>

selenium.common.exceptions.WebDriverException: Message: h is null
Using Firefox 37.0 and selenium 2.45.0.
Observations:
if I switch to webdriver.Chrome() - I don't see any errors
if I use a different URL, e.g. https://google.com - I don't see any errors
I've tried to explicitly wait for search results to be visible before making any further actions, but I still get the same error, code I've used:
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.Firefox()
driver.get("http://www.drugs.com/drug-class/laxatives.html?condition_id=&generic=0&sort=rating&order=desc")
# wait for the table list to load
WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "table.data-list")))
it is not easily googleable which probably means it is web-site specific, but, as noted before, no errors in Chrome
Where is the error coming from and what can I do to prevent/fix it? Does this mean I cannot browser/locate elements on this particular web page using selenium+firefox?

Looks like selenium 2.45.0 does not support ff 37.
The change log shows selenium 2.44 supported FF33. Selenium 2.45 was released around Feb 26th 2015, while FF37 was released on March 31st 2015.

Looks like by the time the page loads it is executing this line of code and throwing an error message.
try to wait till the page loads by using
time.sleep(200)
and keep this line of code under try block as:
try:
WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "table.data-list")))
except:
print("not found")
