# Python | sympy.is_polynomial () method

Python Methods and Functions

With the `sympy.is_polynomial() ` method we can check if a polynomial is found, it will return True as boolean using ` sympy.is_polynomial () `.

Syntax: ` sympy.is_polynomial () `
Return: Return a boolean value if polynomial is found.

Example # 1:
In this example, we can see that with ` sympy.is_polynomial () ` we can detect the polynomial by getting a boolean.

 ` # import sympy ` ` from ` ` sympy ` ` import ` ` * `    ` x, y ` ` = ` ` symbols (` ` 'xy' ` `) ` ` `  ` # Use the sympy.is_polynomial () method ` ` gfg ` ` = ` ` simplify (x ` ` * ` ` * ` ` 2 ` ` + ` ` 2 ` ` * ` ` y ` ` * ` ` x ` ` + ` ` y ` ` * ` ` * ` ` 2 ` `). is_polynomial () `   ` print ` ` (gfg) `

Output:

True

Example No. 2:

 ` # import sympy ` ` from ` ` sympy ` ` import ` ` * `    ` x, y ` ` = ` ` symbols (` `' xy' ` `) `   ` # Use the sympy.is_constant () method ` ` gfg ` ` = ` ` simplify (sin (x)). is_constant () `   ` print ` ` (gfg) `

Output:

False
