With the help of sympy.as_coefficients_dict() method, we are able to find the coefficients of all the elements in the dictionary that exist in the mathematical expression by using sympy.as_coefficients_dict() method.
Syntax :
sympy.as_coefficients_dict()
Return : Return the coefficients of mathematical expression in the dictionary.
Example #1 :
In this example we can see that by using sympy.as_coefficients_dict() method, we can find all the coefficients in a mathematical expression and return a dictionary of it.
# import sympy from sympy import * x = symbols('x') # Use sympy.as_coefficients_dict() method gfg = x**3 + 21 * x + 12 print(gfg.as_coefficients_dict()) |
Output :
defaultdict(, {1: 12, x**3: 1, x: 21})
Example #2 :
# import sympy from sympy import * x = symbols('x') # Use sympy.as_coefficients_dict() method gfg = x**3 + 21 * x**2 + 121 * x + 4 print(gfg.as_coefficients_dict()) |
Output :
defaultdict(, {1: 4, x**3: 1, x**2: 21, x: 121})
