Parsing math expressions correctly involves converting mathematical expressions from their human-readable form into a format that a computer can understand and evaluate. A common approach is to use a parser or library designed for mathematical expressions.

In Python, you can use the sympy library, which provides powerful symbolic mathematics capabilities, including expression parsing and evaluation. Here's an example:

from sympy import sympify, symbols

# Define symbols
x, y = symbols('x y')

# Parse math expressions
expression1 = sympify("2*x + 3*y")
expression2 = sympify("sin(x) + cos(x)")

# Evaluate expressions
result1 = expression1.subs({x: 1, y: 2})
result2 = expression2.subs(x, 0)

print("Result 1:", result1)
print("Result 2:", result2)

In this example, sympify is used to parse the mathematical expressions. You can then substitute values for variables using the subs method.

If you need a more general-purpose parser, you can use the pyparsing library. Here's a basic example:

from pyparsing import Word, nums, operatorPrecedence, opAssoc

# Define grammar for basic math expressions
integer = Word(nums).setParseAction(lambda t: int(t[0]))
variable = Word("xy")
operand = integer | variable
expr = operatorPrecedence(
    operand,
    [
        ("+", 2, opAssoc.LEFT),
        ("-", 2, opAssoc.LEFT),
        ("*", 3, opAssoc.LEFT),
        ("/", 3, opAssoc.LEFT),
    ],
)

# Parse math expressions
expression1 = expr.parseString("2*x + 3*y")
expression2 = expr.parseString("sin(x) + cos(x)")

print("Parsed Expression 1:", expression1)
print("Parsed Expression 2:", expression2)

This example uses pyparsing to define a grammar for basic math expressions with addition, subtraction, multiplication, and division. You can customize the grammar based on your specific needs.

Choose the library that best fits your requirements, whether it's for symbolic mathematics (like sympy) or general-purpose expression parsing (like pyparsing). Always consider error handling and validation when working with user-inputted expressions.

Check the proxy settings: If you are using a proxy on your device or within an application, examine the proxy settings to see if the IP address (or hostname) of the proxy server is mentioned.

Observe the proxy URL: The proxy URL can sometimes indicate the IP address of the proxy server. For example, an HTTP proxy URL usually starts with "http://" or "https://" followed by the proxy server's IP address or hostname, while a SOCKS proxy URL typically starts with "socks://" followed by the proxy server's IP address or hostname.

Consult the proxy provider: If you are unsure about the IP address of the proxy server you are using, you can always consult the proxy provider or the documentation that came with the proxy server. They should be able to provide you with the necessary information about the proxy server's IP address.

Use online tools or software: There are various online tools and software applications that can help you identify the IP address of a proxy. By connecting to the proxy server and analyzing the traffic, these tools can often determine the IP address of the proxy server.

In the messenger settings, go to "Data and Drive". Click on "Proxy settings", and then, enabling the "Use proxy settings" tab, enter the server, port, username and password in the specially highlighted fields. If you are going to make settings in the Desktop version, you will need to go to the menu. There, in the "Connection method" item, click on "TSP via Socks5" and enter the required data.

The current version of Skype does not have built-in functionality to work with proxies. That is, it must be configured at the operating system level. The messenger is available for Linux, Windows, MacOS and mobile platforms.

You can find out your proxy using the Socproxy.ru/ip service from your computer or cell phone. Your IP or proxy address will appear on the main page of the site. Another option is to download the SocialKit Proxy Checker utility, which you can use to check your proxy for validity. If a proxy is used in the browser settings, you can find out its parameters there as well.
