我在這里找到了這個幻想名稱生成器。

我正在嘗試調整代碼以適應我的目的。我想使用name_gen類中的函式自動創建一個 NPC 名稱NPC。NPC的特點是：

class NPC:
  def __init__(self, name, age, gender):
    self.name = name_gen
    self.age = 25
    self.gender = M

我需要的名稱生成器的代碼如下：

from random import randrange

def line_appender(file_path, target):
    file = open(file_path, "r")
    splitfile = file.read().splitlines()
    for line in splitfile:
        target.append(line)

def name_selector(target_list):
    selected = target_list[randrange(len(target_list))]
    return selected

def name_builder(first_name_list_path, last_name_list_path):
    first_name_list = []
    last_name_list = []

    line_appender(first_name_list_path, first_name_list)
    line_appender(last_name_list_path, last_name_list)

    first_name_selected = name_selector(first_name_list)
    last_name_selected = name_selector(last_name_list)

    name = first_name_selected " " last_name_selected
    return name

現在我認為我仍然需要做的唯一一件事就是從類中生成名稱NPC。我想這樣做：

def name_gen
    if gender == "M":
    name = name_builder("first_name_male.txt", "last_name.txt")
    elif gender == "F":
    name = name_builder("first_name_female.txt", "last_name.txt")

但我不明白如何讓name_gen函式檢查class NPC屬性，以便生成所需的名稱。

有人可以幫助我嗎？

Thank you for all the solutions! I am pretty new to Python; In order to test Samwises solution, I tried to run it as a separate script (in order to check whether I would get a name) with the code below. It does however not print anything. I'm putting this in an EDIT because I think it might be a trivial question. If it is worth posting a separate question, please let me know:

import random

running = True

npc_input_messsage = "npc = NPC(25, 'M')"

class NameChooser:
    def __init__(self, file_path):
        with open(file_path) as f:
            self._names = f.read().splitlines()
    
    def choice(self):
        return random.choice(self._names)

first_choosers = {
    "M": NameChooser("first_name_male.txt"),
    "F": NameChooser("first_name_female.txt"),
}
last_chooser = NameChooser("last_name.txt")

def name_gen(gender):
    return f"{first_choosers[gender].choice()} {last_chooser.choice()}" 

class NPC:
    def __init__(self, age, gender):
        self.name = name_gen(gender)
        self.age = age
        self.gender = gender

while running:

    npc = input(npc_input_messsage)

# I'm entering npc = NPC(25, "M")

print(npc)

您的名稱生成器有點過于復雜 IMO。我建議將所有檔案讀取和名稱選擇內容包裝在一個簡單的類中，這樣您就可以定義一次，然后為每個名稱串列實體化它。放入檔案讀取部分__init__意味著您只需在每個串列中執行一次，而不是在每次需要選擇名稱時重新讀取檔案。

import random

class NameChooser:
    def __init__(self, file_path):
        with open(file_path) as f:
            self._names = f.read().splitlines()
    
    def choice(self):
        return random.choice(self._names)

現在您可以定義三個NameChoosers 和一個從中name_gen挑選的函式：

first_choosers = {
    "M": NameChooser("first_name_male.txt"),
    "F": NameChooser("first_name_female.txt"),
}
last_chooser = NameChooser("last_name.txt")

def name_gen(gender):
    return f"{first_choosers[gender].choice()} {last_chooser.choice()}"

現在您可以定義一個NPC將age和gender作為建構式的引數的類，并使用以下方法選擇一個隨機名稱name_gen()：

class NPC:
    def __init__(self, age, gender):
        self.name = name_gen(gender)
        self.age = age
        self.gender = gender

    def __str__(self):
        return f"{self.name} ({self.age}/{self.gender})"


npc = NPC(25, "M")
print(npc)  # prints "Bob Small (25/M)"

我認為您對 OOP 概念感到困惑。

首先，讓我們編輯您的課程：

class NPC:
  def __init__(self, name, age, gender):
    self.name = name
    self.age = age
    self.gender = gender

看，我已經為屬性分配了引數值。現在讓我們更改您的函式：

def name_gen(gender):
    if gender == "M":
        name = name_builder("first_name_male.txt", "last_name.txt")
    elif gender == "F":
        name = name_builder("first_name_female.txt", "last_name.txt")
    return name

在這里，我在您的函式中添加了一個引數，因為您正在使用它的值。現在讓我們為您的類創建一個實體。

npc = NPC("Vishwas", 25, "M") # Instance of the class
print(name_gen(npc.gender)) # Print generated name

一種自動發生的直接方法是簡單地使用該NPC.__init__()方法呼叫名稱生成器。在下面的代碼中，它通過使用下劃線字符開始其名稱而成為該類的私有方法。請注意，對它的呼叫必須等到它參考的所有實體屬性都被賦值。

from random import randrange


class NPC:
    def __init__(self, age, gender):
        self.age = age
        self.gender = gender
        self.name = self._name_gen()

    def _name_gen(self):
        if self.gender == "M":
            name = name_builder("first_name_male.txt", "last_name.txt")
        elif self.gender == "F":
            name = name_builder("first_name_female.txt", "last_name.txt")
        return name


def line_appender(file_path, target):
    file = open(file_path, "r")
    splitfile = file.read().splitlines()
    for line in splitfile:
        target.append(line)

def name_selector(target_list):
    selected = target_list[randrange(len(target_list))]
    return selected

def name_builder(first_name_list_path, last_name_list_path):
    first_name_list = []
    last_name_list = []

    line_appender(first_name_list_path, first_name_list)
    line_appender(last_name_list_path, last_name_list)

    first_name_selected = name_selector(first_name_list)
    last_name_selected = name_selector(last_name_list)

    name = first_name_selected " " last_name_selected
    return name

if __name__ == '__main__':
    npc1 = NPC(25, 'M')
    print(f'{npc1.name!r}')
    npc2 = NPC(21, 'F')
    print(f'{npc2.name!r}')
