With the help of sympy.collect() method, we are able to collect the mathematical expressions having same power.
Syntax :
sympy.collect()
Return : Return mathematical expression having same powers.
Example #1 :
In this example, we can see that by using sympy.collect() method, all the same powers of variables are collected together as a same mathematical expression.
# import sympy from sympy import * x, y, z = symbols('x y z') gfg_exp = x * y + x - 3 + 2 * x**2 - z * x**2 + x**3 # Using sympy.collect() method gfg_exp = collect(gfg_exp, x) print(gfg_exp) |
Output :
x**3 + x**2*(2 – z) + x*(y + 1) – 3
Example #2 :
# import sympy from sympy import * x, y, z = symbols('x y z') gfg_exp = x * x + x - 3 + 2 * z**2 - y * x**2 + x**3 # Using sympy.collect() method gfg_exp = collect(gfg_exp, x) print(gfg_exp) |
Output :
x**3 + x**2*(1 – y) + x + 2*z**2 – 3
