Example #1 :
In this example we can see that we are able to perform any mathematical operation by using sympy.Lambda() method.




# import sympy
from sympy import *
  
# Use sympy.Lambda() method
x = symbols('x')
gfg = Lambda(x, x + 1)
  
print(gfg(9))

Output :

10



Example #2 :




# import sympy
from sympy import *
  
# Use sympy.Lambda() method
x, y = symbols('x y')
gfg = Lambda((x, y), x * y)
  
print(gfg(9, 5))

Output :

45
