Get a value from solution set returned as finiteset by Sympy

Get a value from solution set returned as finiteset by Sympy

In SymPy, when you solve an equation or expression, you might get a solution set represented as a FiniteSet object. To extract a specific value from the FiniteSet, you can use indexing or conversion to a Python list.

Here's how you can do it:

from sympy import symbols, solve, FiniteSet # Define the symbol x = symbols('x') # Solve the equation equation = x**2 - 4 solutions = solve(equation, x) # Get a specific value from the solution set using indexing value_at_index_0 = solutions[0] value_at_index_1 = solutions[1] print("Value at index 0:", value_at_index_0) print("Value at index 1:", value_at_index_1)

Alternatively, if you want to convert the FiniteSet into a Python list, you can use the list() function:

solutions_list = list(solutions) print("Solutions as a list:", solutions_list)

Remember that the order of solutions in a FiniteSet might not be guaranteed to match the order of the solutions you see in mathematical notation. If you need to perform operations on the solutions or manipulate them, it's often a good idea to convert them to a list or another appropriate data structure first.
