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))
