# Python | sympy.compare () method

Python Methods and Functions

Using the `sympy.compare() ` method we can compare the variables and it will return 3 values, i.e. -1 for less, 0 for equal and 1 for greater, using ` sympy.compare () `.

Syntax: ` sympy .compare () `
Return: Return the value of comparison ie -1, 0, 1.

Example No. 1:
In this example we can see that using ` sympy.compare () ` we can compare variables and return 3 values, i.e. -1 for less, 0 for equal and 1 for greater.

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

Output:

-1

Example # 2:

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

Output:

0

Example # 3:

` `

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

` `

Output:
