If PyCharm is not recognizing the Selenium library, there are a few steps you can take to resolve the issue

1. Check Project Interpreter

Ensure that you have the correct Python interpreter selected for your project. Open PyCharm, go to File > Settings > Project > Project Interpreter. Make sure that the interpreter you are using has Selenium installed.

2. Install Selenium

Install the Selenium library if you haven't done so. You can install it using the following pip command in your terminal or command prompt:

pip install selenium

3. PyCharm Reindexing:

   • Sometimes, PyCharm may not automatically recognize installed packages. Try restarting PyCharm, and it will perform a reindexing of your project. This may resolve the issue.

4. Virtual Environment:

   • If you are using a virtual environment, make sure it is activated. PyCharm should recognize the packages installed within the virtual environment.

5. PyCharm Cache:

   • Clear PyCharm's cache. Go to File > Invalidate Caches / Restart... and select "Invalidate and Restart." This will clear the caches and restart PyCharm.

6. Check Project Structure:

   • Verify that your project structure is set up correctly. The directory containing your Selenium scripts should be marked as the source root. Right-click on the directory and select Mark Directory as > Sources Root.

7. Check Python Path:

   • Verify that the Python path in PyCharm matches the path where Selenium is installed. You can check this in the Project Interpreter settings.

8. Check for Typos:

   • Ensure there are no typos or mistakes in your code. PyCharm might not recognize the library if there are syntax errors or import issues.

9. PyCharm Plugin:

   • Check if you have a PyCharm plugin related to Selenium. Some plugins provide additional support for Selenium. Make sure it is installed and enabled.

10. Update PyCharm:

    • Ensure that you are using the latest version of PyCharm. Updating to the latest version may resolve compatibility issues.

11. Recreate Virtual Environment (if applicable):

    • If you are using a virtual environment, try recreating it. Activate the new virtual environment and install Selenium again.

After going through these steps, PyCharm should recognize the Selenium library. If the issue persists, double-check your project configuration and make sure there are no conflicting settings or issues with your Python environment.

Building a chain of proxies in Selenium involves configuring a WebDriver with a Proxy object that represents a chain of proxies. Here's an example using Python with Selenium and the Chrome WebDriver:

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

# Create a Proxy object for the first proxy in the chain
proxy1 = Proxy()
proxy1.http_proxy = "http://proxy1.example.com:8080"
proxy1.ssl_proxy = "http://proxy1.example.com:8080"
proxy1.proxy_type = ProxyType.MANUAL

# Create a Proxy object for the second proxy in the chain
proxy2 = Proxy()
proxy2.http_proxy = "http://proxy2.example.com:8080"
proxy2.ssl_proxy = "http://proxy2.example.com:8080"
proxy2.proxy_type = ProxyType.MANUAL

# Create a Proxy object for the final proxy in the chain
proxy3 = Proxy()
proxy3.http_proxy = "http://proxy3.example.com:8080"
proxy3.ssl_proxy = "http://proxy3.example.com:8080"
proxy3.proxy_type = ProxyType.MANUAL

# Create a chain of proxies
proxies_chain = f"{proxy1.proxy, proxy2.proxy, proxy3.proxy}"

# Set up ChromeOptions with the proxy chain
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f"--proxy-server={proxies_chain}")

# Create the WebDriver with ChromeOptions
driver = webdriver.Chrome(options=chrome_options)

# Now you can use the driver with the proxy chain for your automation tasks
driver.get("https://example.com")

# Close the browser window when done
driver.quit()

In this example:

Three Proxy objects (proxy1, proxy2, and proxy3) are created, each representing a different proxy in the chain. You need to replace the placeholder URLs (http://proxy1.example.com:8080, etc.) with the actual proxy server URLs.

The ProxyType.MANUAL option is used to indicate that the proxy settings are configured manually.

The proxies_chain variable is a comma-separated string representing the chain of proxies.

The --proxy-server option is added to ChromeOptions to specify the proxy chain.

A Chrome WebDriver instance is created with the configured ChromeOptions.

Although free proxies are popular, they are far from being flawless in their work. Many of their IP addresses are blacklisted by popular resources, and the data transfer speed and stability are very unreliable. When choosing a proxy, keep in mind that the new version of IPv6 is not supported by most websites. Note also that proxies are divided into private and public, statistical and dynamic, and support different network protocols.

And it depends on what purpose the proxy is used for. But you should definitely give preference to paid proxies. They are more reliable, always available, and with that comes a guarantee of privacy. Unfortunately, personal data is often stolen from free proxies.

Using the Internet in normal mode leads to loss of anonymity. In this case, the computer connects directly to the servers of sites and applications, recognizing the personal IP address and other confidential information. The use of redirecting proxy servers protects against all these unwanted consequences and allows you to bypass potential blocking. In order to take advantage of proxy servers of several types and varieties, it is necessary to install them properly.
