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)])
