sk-variable-handler 1.0.102

A simple Variable Handling program

Variable Handler

This is a Python package that provides a VariableHandler class for extracting variable values from a string of variable declarations.

Installation

To use the VariableHandler package, you need to install it first. You can install it using pip:

pip install sk_variable_handler

Usage

To extract variable values from a string of variable declarations, follow these steps:

1. Import the VariableHandler class from the variable_handler module:

   from sk_variable_handler import VariableHandler
   

2. Create an instance of the VariableHandler class:

   variable_handler = VariableHandler()
   

3. Call the get_values method of the VariableHandler instance, passing the string of variable declarations as an argument. It returns a dictionary containing the variable names as keys and their corresponding values as values.

   declarations = "Your variable declarations"
   values = variable_handler.get_values(declarations)
   

Example

Here is an example that demonstrates the usage of the VariableHandler:

from variable_handler import VariableHandler

variable_handler = VariableHandler()

declarations = "$x=1+2;$y=2+1;$var=12+223+(222+2)+sin(90);$var2=$x+$y;$xy=($var2+$x+$y);$yx=$xy+$var2"
expected_result = {'$x': '3.0', '$y': '3.0', '$var': '460.0', '$var2': '6.0', '$xy': '12.0', '$yx': '18.0'}

result = variable_handler.get_values(declarations)
assert result == expected_result

Test Cases

The package includes a set of unit tests to verify the functionality of the VariableHandler class. The tests cover various scenarios and edge cases to ensure the correct extraction of variable values.

To run the tests, execute the script as a standalone Python program:

python <filename>.py

The output will indicate whether all the tests have passed or if there are any failures.

Please note that the tests are implemented using the unittest framework. Each test case is independent and tests a specific aspect of the VariableHandler functionality.
