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.

Sending large files over UDP can be a bit tricky because UDP does not guarantee delivery, order, or even that packets won't be duplicated. However, it is possible to send large files using UDP by breaking the file into smaller chunks and sending each chunk separately. Here's a step-by-step guide on how to do it in Python:

1. Import necessary libraries:

import os
import socket
import pickle

2. Define a function to serialize the file data:

def serialize_file_data(file_data):
    return pickle.dumps(file_data)

3. Create a UDP socket:

def create_udp_socket(host, port):
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    sock.bind((host, port))
    return sock

4. Send the file data over UDP:

def send_file(sock, file_data, host, port):
    serialized_file_data = serialize_file_data(file_data)
    sock.sendto(serialized_file_data, (host, port))

5. Define a function to deserialize the file data:

def deserialize_file_data(file_data):
    return pickle.loads(file_data)

6. Create a function to receive the file data:

def receive_file(sock, host, port):
    while True:
        data, addr = sock.recvfrom(4096)
        file_data = deserialize_file_data(data)
        yield file_data

7. Putting it all together:

if __name__ == "__main__":
    file_path = "large_file.txt"
    host, port = "127.0.0.1", 12345
    sock = create_udp_socket(host, port)
    send_file(sock, file_path, host, port)

On the receiving side, you will need to collect all the received file data and save it to a file.

There is often no need to use a proxy server on PS4. However, using a proxy can achieve the following results:

opening access to inaccessible social networks and streaming sites; removal of the block on a personal IP; anonymous use of services; increasing account protection from hacking and network attacks. Without the need to use a proxy server on PS4 makes no sense.

A firewall is responsible for filtering packets of traffic. For example, it blocks access to the Internet for certain applications. There are many more options for using a proxy. But if you install special software, it can also be used for such purposes.

The most convenient way is to use online proxy checkers, i.e. services that test all connection capabilities, including supported protocols. For example, Hidemy.name or Securitylab. As for applications, you can recommend SocksChain or Open Proxy Checker.
