Playmaker Hashtable Proxy

To check the quality of a proxy server, you can use one of the proxy checkers. There are a lot of them on the Internet. For example, hidemy.name. On the page of the checker you need to specify the IP-address and port of the required proxy server.

Explicit and implicit waiting are two types of waiting strategies used in Selenium WebDriver to handle synchronization issues in web applications. They help in dealing with elements that are not immediately available on the page when the test starts.

Explicit Wait:

Explicit wait is used when you know exactly which element you are waiting for and how long you want to wait for that element to be available. It uses the WebDriverWait class to wait for a specified condition to be true for a specified amount of time. Explicit wait is more reliable and is generally recommended when you know the expected conditions.

The main components of explicit wait are:

- WebDriverWait: It is a class that provides a way to wait for a condition to be true for a specified amount of time.

- ExpectedConditions: It is a class that provides a way to specify the condition to be true.

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("http://example.com")

# Explicit wait for an element to be present
wait = WebDriverWait(driver, 10)
element = wait.until(EC.presence_of_element_located((By.ID, "myElement")))

Implicit Wait:

Implicit wait is a global setting that applies to all find_element and find_elements calls in a test. It tells the WebDriver to wait for a specified amount of time for an element to be available before throwing a NoSuchElementException. Implicit wait is less reliable than explicit wait because it applies to all elements in the test, not just the specific one you are waiting for.

The main components of implicit wait are:

ImplicitlyWait: It is a method used to set the amount of time the WebDriver should wait for an element to be available before throwing a NoSuchElementException.

from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException

driver = webdriver.Chrome()
driver.implicitly_wait(10) # Set implicit wait to 10 seconds
driver.get("http://example.com")

try:
    element = driver.find_element(By.ID, "myElement")
except NoSuchElementException:
    print("Element not found")

In summary, the main difference between explicit and implicit waiting in Selenium is that explicit wait is used for waiting for a specific condition to be true for a specified amount of time, while implicit wait is a global setting that applies to all find_element and find_elements calls in a test. Explicit wait is more reliable and is generally recommended for specific scenarios, while implicit wait is less reliable but simpler to use for general cases.

There are lots of ways to use them. For example, you can swap your real IP address location for an American one, thus getting the opportunity to watch Netflix at a bargain price. Or you can set up parsing traffic through a proxy to test the security of your web applications. Or you can create a proxy server on your local network that allows traffic through and blocks requests to certain sites.

You can check the validity of proxies by using special software and a proxy checker. These tools not only check if the proxy is working, but also inform you about possible blocking by various platforms and social networks. Online services (checkers) also provide information related to ping, speed, proxy anonymity level, and geo. The combination of all these data allows for the most objective assessment of a proxy server's performance.

If you plan to use a proxy every day, it is recommended to pay attention to paid services. There, the connection is as reliable as possible, with no bandwidth limitations. However, the performance of numerous free proxies is not guaranteed.
