In this question, we want to return the function like this result but I do not want things like 0^5 to occur(because 0^5 is equal to 0 and I do not want to show that, how can I write a code to let the system detect that the several parts are 0? And when I want to use the degree function in Class Poly, i want the inserted poly number to be the highest coefficient, how can I do that? we can place the insert function later, that is my code:

Class Poly():
    def __init__(self,coe=[]):
        self.coefficient=coe
    def degree(self,poly=int()):
        self.highestpoly=poly
    def insert(self,polynomial,coefficient):
        self.polynomial=polynomial
        self.coefficient=coefficient #solve that later
    def __str__(self):
        e=self.coefficient[5]
        c=self.coefficient[4]
        a=self.coefficient[3]
        b=self.coefficient[2]
        z=self.coefficient[1]
        d=self.coefficient[0]
        epart=str(e) str("^") str(5) ' '
        cpart=str(c) str("^") str(4) ' '
        apart=str(a) str("^") str(3) ' '
        bpart=str(b) str("^") str(2) ' '
        zpart=str(c) str("^") str(1) ' '
        dpart=str(d)
        return epart cpart apart bpart zpart dpart


print(Poly([0,0,3,2,1,0]))
>>> tommy1111@infra04-wg013 lab11 % python3 -i mycode.py 0^5 1^4 2^3 3^2 1^1 0 (result)

CodePudding user response：

Here is the code I think you want, the order of the coefficients is wrong but That wasn't the main issue.

class Poly():
    def __init__(self, coe=None):
        if coe is None:
            coe = []
        self.coefficient = coe

    def degree(self, poly=int()):
        self.highestpoly = poly

    def insert(self, polynomial, coefficient):
        self.polynomial = polynomial
        self.coefficient = coefficient  # solve that later

    def __str__(self):
        p = []
        for i, c in enumerate(self.coefficient):
            if c != 0:
                p.append(f"{c}x^{i}")

        return "   ".join(p)

print(Poly([0,0,3,2,1,0]))

output:

3x^2   2x^3   1x^4
