Python | sympy.as_coefficient() method

With the help of sympy.as_coefficient() method, we can find the coefficient of any element in the mathematical expression by using sympy.as_coefficient() method.

Syntax : sympy.as_coefficient()
Return : Return the coefficient of any element.

Example #1 :
In this we can see that by using sympy.as_coefficient() method, we are able to get the values of coefficient of any element that is passed as parameter.

# import sympy
from sympy import *

x = symbols('x')

# Use sympy.as_coefficient() method
gfg = x**3 + 21 * x + 12

print(gfg.as_coefficient(x))

Output :

21

Example #2 :

# import sympy
from sympy import *

x = symbols('x')

# Use sympy.as_coefficient() method
gfg = x**3 + 21 * x**2 + 121x + 4

print(gfg.as_coefficient(x))

Output :

121
