With the help of sympy.coeff(x, n) method, we are able to find the coefficient of variables in mathematical expressions.
Syntax :
sympy.coeff(x, n)
Return : Return the coefficient of variables.
Example #1 :
In this example, we can see that by using sympy.coeff(x, n) method, we can find the coefficient of mathematical expression.
# import sympy from sympy import * x, y, z = symbols('x y z')
gfg_exp = x * y + x - 3 + 2 * x**2 - z * x**2 + x**3
# Using sympy.coeff(x, n) method gfg_exp = gfg_exp.coeff(x, 2)
print(gfg_exp)
|
Output :
2 – z
Example #2 :
# import sympy from sympy import * x, y, z = symbols('x y z')
gfg_exp = z * x + x - 3 + 2 * x**2 - y * x**2 + y**3
# Using sympy.coeff(x, n) method gfg_exp = gfg_exp.coeff(y, 1)
print(gfg_exp)
|
Output :
-x**2
