Rotary proxies are proxies that cyclically change their real IP address. This is used to make it harder to track their location. The port usually changes as well. How this happens depends on the software used on the proxy server.
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.
Technically, the ISP cannot block all VPN servers. But it is possible to block some of them. In this case, you can use any other VPN service. But you have to be careful with "free" ones, as they often make money from collecting and selling users' confidential data.
