• Last Updated : 19 Jul, 2019

With the help of `sympy.compare()` method, we can compare the variables and it will return 3 values i.e -1 for smaller, 0 for equal and 1 for greater by using `sympy.compare()` method.

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

Example #1 :
In this example we can see that by using `sympy.compare()` method, we are able to compare the variables and return 3 values i.e -1 for smaller, 0 for equal and 1 for greater.

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

Output :

-1

Example #2 :

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

Output :

0

Example #3 :

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

Output :
