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.
# 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 :
# 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
