在Python中顯示重復的結果

我的代碼：

import random

class human:
    'humans class'
    def __init__(self,fname,lname=None,age=None):
        self.fname = fname
        if lname != None: self.lname = lname 
        else: self.lname = None
        if age != None: self.age = age 
        else: self.age = None

    def new(self,command):
        "for define a new variable"
        return exec(command)


class soccer_player(human):
    "soccer players class"
    
    all_players = []
    choised = []
    a = []
    b = []
    def __init__(self, fname, lname=None, age=None):
        super().__init__(fname, lname=lname, age=age)
        soccer_player.all_players.append(fname)
    
    def start_random_choise():
        i=0
        while True:
            choise = random.choice(soccer_player.all_players)
            if choise not in soccer_player.choised:
                soccer_player.a.append(choise)
                i = i   1
            if i == 11:
                break
        i=0
        while True:
            choise = random.choice(soccer_player.all_players)
            if choise not in soccer_player.choised:
                soccer_player.b.append(choise)
                i = i   1
            if i == 11:
                break

hosein = soccer_player("hosain")
maziar = soccer_player("maziar")
akbar = soccer_player("akbar")
nima = soccer_player("mina")
mehdi = soccer_player("mehdi")
farhad = soccer_player("farhad")
mohammad = soccer_player("mohammad")
khashaiar = soccer_player("khashaiar")
milad = soccer_player("milad")
mostafa = soccer_player("mostafa")
amin = soccer_player("amin")
saeed = soccer_player("saeed")
poya = soccer_player("poya")
porya = soccer_player("porya")
reza = soccer_player("reza")
ali = soccer_player("ali")
behzad = soccer_player("behzad")
sohail = soccer_player("sohail")
behrooz = soccer_player("behrooz")
shahrooz = soccer_player("shahrooz")
saman = soccer_player("saman")
mohsen = soccer_player("mohsen")

soccer_player.start_random_choise()

print("A:",end=" ")
for i in list(range(len(soccer_player.a))):
    print(soccer_player.a[i],end=" , ")
print()
print("B:",end=" ")
for i in list(range(len(soccer_player.b))):
    print(soccer_player.b[i],end=" , ")
print()

我的問題是這個應用程式顯示重復的結果：

[nimafanniasl@fedora prs]$ python -u "/home/nimafanniasl/pr.py"
A: mehdi , porya , maziar , porya , akbar , porya , behzad , amin , khashaiar , maziar , ali , 
B: hosain , mohammad , mostafa , shahrooz , mostafa , poya , mostafa , hosain , farhad , hosain , hosain ,

這個應用程式在 B 隊列印了 4 個 hesein，請幫我制作這個程式，這樣它就不會顯示重復的結果

uj5u.com熱心網友回復：

您沒有將所選玩家添加到choised. 添加這一行

soccer_player.choised.append(choise)

在兩個 while 回圈中。

uj5u.com熱心網友回復：

1. 您的 if 條件被破壞，因為您檢查了錯誤的串列。您將玩家附加到soccer_player.a.append(choise)orb但您的條件狀態if choise not in soccer_player.choised。您可能也打算將玩家附加到choised串列中。

2. 如果你用random.sample或random.shuffle已經保證它們不會產生重復的代碼替換大部分代碼，你就可以避免做所有這些作業。

    def start_random_choise():
        soccer_player.a = random.sample(soccer_player.all_players, 11)
        soccer_player.b = random.sample(soccer_player.all_players, 11)

3. 請查看“生日悖論”，了解為什么您的代碼效率低下
