Python | sympy.is_rational method

With the help of sympy.is_rational method, we can check whether the element is rational or not this method will return the boolean value i.e True or False.

Syntax : sympy.is_rational Return : Return True if rational else False.

Example #1: In this example, we can see that by using sympy.is_rational method, we are able to check the rational value and it will return a boolean value. 

Python3

# import sympy
from sympy import *

# Use sympy.is_rational method
gfg = simplify(2 / 5).is_rational

print(gfg)

Output :

True

Example #2 :

Python3

# import sympy
from sympy import *

# Use sympy.is_rational method
gfg = simplify(5).is_rational

print(gfg)

Output :

True

Example #3 : 

Python3

# import sympy
from sympy import *

# Use sympy.is_rational method
gfg = simplify(sqrt(3)).is_rational

print(gfg)
