Cannot locate form-control object to send_keys using python Selenium

I am trying to navigate a scheduling website to eventually auto populate a schedule using the following script:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
# Create a Chrome webdriver
driver = webdriver.Chrome(r'C:\Users\chromedriver_win32\chromedriver.exe')
# Navigate to https://www.qgenda.com/
driver.get('https://www.qgenda.com/')
# Wait for the page to load
driver.implicitly_wait(5) # 5 seconds
# You can now interact with the page using the webdriver
# Locate the sign in button
sign_in_button = driver.find_element(By.XPATH,'/html/body/div[1]/div/header[3]/div/div[3]/div/div/div/div/a')
# Click the sign in button
sign_in_button.click()
# Find the input element
input_email = driver.find_element(By.XPATH,'//*[#id="Input_Email"]')
# Send text
input_email.send_keys('Josh')
However, I cannot seem to find the Input_Email object. I've tried all the Xpaths and Id's that make sense and also tried waiting until the object is clickable with no luck. Would really appreciate some guidance on this.
I was expecting Selenium to find the html object form box and pass in text but instead I get an error:
NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//*[#id="Input_Email"]"}
even though the Xpath definitely exists.

The XPath seems fine. I am guessing you need to do some explicit wait or implicit wait to ensure the page is fully loaded before allocating the element.
Another thing I would like to point out is that given the login URL is available. Locating the sign in button seems to be redundant. You can access it directly via driver.get('https://login.qgenda.com/')
For instance,
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver.get('https://login.qgenda.com/')
input_email = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.XPATH, '//*[#id="Input_Email"]'))
)
input_email.send_keys('Josh')

Unable to locate element within an iframe through Selenium

I'm new to Selenium. I'm trying to write a Python script that will log in to a particular form. The form is located at http://www.tvta.ca/securedContent
The code I'm running is:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://tvta.ca/securedContent/")
elem = driver.find_element_by_name("txtUserName")
elem.clear()
elem.send_keys("<<my email>>")
I get an error that says:
selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: [name="txtUserName"]
I'm not sure what I'm missing here? I've checked the source of the webpage the login field is definitely named txtUserName.

You need to switch to the frame to write text in the textbox, try to check syntax once as I have less in good in Python
framLogin= driver.find_element_by_id("membeeLoginIF")
driver.switch_to.frame(framLogin)
EmailTxt = driver.find_element_by_name("txtUserName");
EmailTxt.send_Keys("Test#gmail.com");
Same in Java
WebElement framLogin= driver.findElement(By.id("membeeLoginIF"));
driver.switchTo().frame(framLogin);
WebElement EmailTxt = driver.findElement(By.name("txtUserName"));
EmailTxt.sendKeys("Test#gmail.com");

That site requires third-party cookies to be enabled; without them, the login form does not load. It's likely you have your browser configured that way but the defaults for webdriver.Firefox do not.
To see what Selenium is actually seeing, dump driver.page_source and/or take a screenshot with driver.save_screenshot(...).

The desired element is within an <iframe>. So as per best practices you have to:
Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable and you can use the following Locator Strategies:
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"membeeLoginIF")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.textboxWaterMark#txtUserName"))).send_keys("Jeff")
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

Access nested elements in HTML using Python Selenium

I am trying to automate logging into a website (http://www.phptravels.net/) using Selenium - Python on Chrome. This is an open website used for automation tutorials.
I am trying to click an element to open a drop-down (My Account button at the top navbar) which will then give me the option to login and redirect me to the login page.
The HTML is nested with many div and ul/li tags.
I have tried various lines of code but haven't been able to make much progress.
driver.find_element_by_id('li_myaccount').click()
driver.find_element_by_link_text(' Login').click()
driver.find_element_by_xpath("//*[#id='li_myaccount']/ul/li[1]/a").click()
These are some of the examples that I tried out. All of them failed with the error "element not visible".
How do I find those elements? Even the xpath function is throwing this error.
I have not added any time wait in my code.
Any ideas how to proceed further?

Hope this code will help:
from selenium import webdriver
from selenium.webdriver.common.by import By
url="http://www.phptravels.net/"
d=webdriver.Chrome()
d.maximize_window()
d.get(url)
d.find_element(By.LINK_TEXT,'MY ACCOUNT').click()
d.find_element(By.LINK_TEXT,'Login').click()
d.find_element(By.NAME,"username").send_keys("Test")
d.find_element(By.NAME,"password").send_keys("Test")
d.find_element(By.XPATH,"//button[text()='Login']").click()
Use the best available locator on your html page, so that you need not to create xpath of css for simple operations

You may be having issues with the page not being loaded when you try and find the element of interest. You should use the WebDriverWait class to wait until a given element is present in the page.
Adapted from the docs:
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
# Set up your driver here....
try:
element = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.ID, 'li_myaccount'))
)
element.click()
except:
#Handle any exceptions here
finally:
driver.quit()

Python with selenium webscraping unable to find elements

I am trying to write a webscraping in python that will activate the "onclick" functionality of certain buttons on a webpage because the tables with the data I want are converted to csv, which makes it much easier to access. But the problem is that I am unable to locate elements by xpath at all when using PhantomJs. How can I click the element and access the csv content that I want?
This is my code:
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.common.by import By
from selenium.webdriver.common.proxy import *
url = "http://www.pro-football-reference.com/boxscores/201609180nwe.htm"
xpath = "//*[#id='all_player_offense']/div[1]/div/ul/li[1]/div/ul/li[3]/button"
path_to_phantomjs = 'browser/phantomjs'
browser = webdriver.PhantomJS(executable_path = path_to_phantomjs)
browser.get(url)
delay=3
element_present = EC.presence_of_element_located((By.ID, 'all_player_offense'))
WebDriverWait(browser, delay).until(element_present)
browser.find_element_by_xpath(xpath).click()
And I get this error:
selenium.common.exceptions.NoSuchElementException: Message: {"errorMessage":"Unable to find element with xpath '//*[#id='all_player_offense']/div[1]/div/ul/li[1]/div/ul/li[3]/button'","request":{"headers":{"Accept":"application/json","Accept-Encoding":"identity","Connection":"close","Content-Length":"153","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:50989","User-Agent":"Python-urllib/2.7"},"httpVersion":"1.1","method":"POST","post":"{\"using\": \"xpath\", \"sessionId\": \"93ff24f0-9cbe-11e6-8711-bdfa3ff9cfb1\", \"value\": \"//*[#id='all_player_offense']/div[1]/div/ul/li[1]/div/ul/li[3]/button\"}","url":"/element","urlParsed":{"anchor":"","query":"","file":"element","directory":"/","path":"/element","relative":"/element","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/element","queryKey":{},"chunks":["element"]},"urlOriginal":"/session/93ff24f0-9cbe-11e6-8711-bdfa3ff9cfb1/element"}}
Screenshot: available via screen

IMPORTANT THING I FORGOT TO MENTION: As described in this this issue on GitHub, try putting set_window_size(width, height) or maximize_window()after setting the webdriver. You should also consider telling the webdriver to implicitly_wait(10) for the element to appear.
So there's a special maneuver you have to perform in order for the Selenium Webdriver to properly emulate what you're doing. In essence, to get the desired data, you'd have to:
A: Hover over the "Share & More" dropdown menu. Then
B: Click "Get table as CSV (Excel)".
For A, this involves having to place the emulated cursor on the element without clicking it. This idea of "mouse over" can be done with the move_to_element() function provided in the ActionChains class. So at the top you'd insert this:
from selenium.webdriver.common.action_chains import ActionChains
You want Selenium to find the specific element and move to it. You can achieve this with 2 lines of code:
dropdown = browser.find_element_by_xpath('//*[#id="all_player_offense"]/div[1]/div/ul/li[1]')
ActionChains(browser).move_to_element(dropdown).perform()
If you omit the above, you'll get an ElementNotVisibleException.
Now for B, you should be able to do browser.find_element_by_xpath(xpath).click().

cannot locate element within a web page using selenium python

I just want to write a simple log in code for one website. However, I think the log in page was written in JS. It's really hard to locate the elements with selenium.
The web page I am going to play with is:
"https://www.nike.com/snkrs/login?returnUrl=%2F"
This is how the page looks like and how the inspect element page look like:
I was trying to locate the element by following code:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
driver = webdriver.Firefox()
driver.get("https://www.nike.com/snkrs/login?returnUrl=%2Fthread%2Fe9680e08e7e3cd76b8832684037a58a369cad5ed")
time.sleep(5)
driver.switch_to.frame(driver.find_element_by_tag_name("iframe"))
elem =driver.find_element_by_xpath("//*[#id='ce3feab5-6156-441a-970e-23544473a623']")
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
driver.close()
This code return the error that the element could not find by [#id='ce3feab5-6156-441a-970e-23544473a623'.
I tried playing with frames, it seems does not work. If I went to "view web source" page, it is full of JS code.
Is there a good way to play with such a web page with selenium?

Try changing the code :
elem =driver.find_element_by_xpath("//*[#id='ce3feab5-6156-441a-970e-23544473a623']")
to
elem =driver.find_element_by_xpath("//*[#type='email']")

My guess (and observation) is that the id changes each time you visit the page. The id looks auto-generated, and when I go to the page multiple times, the id is different each time.
You'll need to search for something that doesn't change. For example, you can search for the name attribute, which has the seemingly static value "emailAddress"
element = driver.find_element_by_name("emailAddress")
You could also use an xpath expression to search for other attributes, such as data-componentname:
element = driver.find_element_by_xpath("//input[#data-componentname='emailAddress']")
Also, instead of a hard-coded sleep, you can simply wait for the element to be visible:
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("https://www.nike.com/snkrs/login")
element = WebDriverWait(driver, 10).until(
EC.visibility_of_element_located((By.NAME, "emailAddress"))
)
