Python | sympy.expand() method

Last Updated : 8 Dec, 2022
With the help of sympy.expand() method, we can expand the mathematical expressions in the form of variables by using sympy.expand() method.
Syntax : sympy.expand(expression) Return : Return mathematical expression.
Example #1 : In this example we can see that by using sympy.expand() method, we can get the mathematical expression with variables. Here we use symbols() method also to declare a variable as symbol. Python3 1=1
# import sympy
from sympy import expand, symbols

x, y = symbols('x y')
gfg_exp = x + y

# Use expand() method from sympy
exp = expand(gfg_exp**2)
print(exp)
Output :
x**2 + 2*x*y + y**2
Example #2 : Python3 1=1
# import sympy
from sympy import expand, symbols

x, y, z = symbols('x y z')
gfg_exp = x + y + z

# Use expand() method from sympy
exp = expand(gfg_exp**2)
print(exp)
Output :
x**2 + 2*x*y + 2*x*z + y**2 + 2*y*z + z**2
