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)
|
Output :
False
