With the help of sympy.factor_list() method, we can get a list of factors of a mathematical expression in SymPy in the form of (factor, power) tuple.
Syntax: factor_list(expression)
Parameters:
expression – It is a mathematical expression.Returns: Returns a list of factors of the given mathematical expression in the form of (factor, power) tuple.
Example #1:
In this example we can see that by using sympy.factor_list() method, we can get a list of factors of a given mathematical expression.
# import sympy from sympy import * x = symbols('x') expr = x**2 * z + 4 * x*y * z + 4 * y**2 * z print("Mathematical expression : {}".format(expr)) # Use sympy.factor_list() method f = factor_list(expr) print("List of factors : {}".format(f)) |
Output:
Mathematical expression : x**2*z + 4*x*y*z + 4*y**2*z List of factors : (1, [(z, 1), (x + 2*y, 2)])
Example #2:
# import sympy from sympy import * x = symbols('x') expr = (x**2 - 2 * x + 1) print("Mathematical expression : {}".format(expr)) # Use sympy.factor_list() method f = factor_list(expr) print("List of factors : {}".format(f)) |
Output:
Mathematical expression : x**2 - 2*x + 1 List of factors : (1, [(x - 1, 2)])
