Python | sympy.symbols() method

Last Updated : 02 Aug, 2019

With the help of sympy.symbols() method, we can declare some variables for the use of mathematical expression and polynomials by using sympy.symbols() method.

Syntax : sympy.symbols() Return : Return nothing or None.

Example #1 : In this example we can see that by using sympy.symbols() method, we are able to get the variables for mathematical expression and polynomials.

Python3 1=1

# import sympy
from sympy import *

# Use sympy.symbols() method
x, y = symbols('x y')
x = 2
gfg = x**2 + 4 * x + 4

print(gfg)

Output :

16

Example #2 :

Python3 1=1

# import sympy
from sympy import *

# Use sympy.symbols() method
x, y = symbols('x y')
x = 5
y = 5
gfg = x**2 + y

print(gfg)

Output :

30
