Python | sympy.is_number method

Last Updated : 26 Jul, 2019

With the help of sympy.is_number method, we can check if element is number or not and it will return a boolean value if number is found by using sympy.is_number method.

Syntax : sympy.is_number Return : Return a boolean value if number is found.

Example #1 : In this example we can see that by using sympy.is_number() method, we are able to detect the number by getting boolean value.

Python3 1=1

# import sympy
from sympy import * 

x, y = symbols('x y')

# Use sympy.is_number method
gfg = cos(2).is_number
   
print(gfg)

Output :

True

Example #2 :

Python3 1=1

# import sympy
from sympy import * 

x, y = symbols('x y')

# Use sympy.is_number method
gfg = sin(x).is_number
   
print(gfg)

Output :

False
