Python | sympy.S() method

With the help of sympy.S() method, we can make a single instance of an object by using sympy.S() method, where S denotes to singleton class.

Syntax : sympy.S()
Return : Return the single instance of an object.

Example #1 :
In this example we can see that by using sympy.S() method, we are able to create a single instance of any object.

# import sympy
from sympy import *

# Use sympy.S() method
gfg = Integer(0)

print(gfg == S.Zero)

Output :

True

Example #2 :

# import sympy
from sympy import *

# Use sympy.S() method
gfg = Rational(1, 2)

print(gfg == S.Half)

Output :

True
