Question

我正在尝试将随机生成的数字添加到文本文件中，因为我将一个文件中的名称读入另一个文件中。这是我的代码：

def dogs():
    total_cards = int(input("How many cards do you wish to play with? "))
    N = int(total_cards)
    Y = int(N/2)
    Z = int(N/2)

    with open("dogs.txt") as f:  # Opens needed file
            with open("dogswrite.txt", "w") as f1:  # My own file for player names
                for i in range(Y):
                    line_name = next(f).strip()  # Lists the input number of results each on a new line
                    line_name = line_name + "\n"
                    f1.write(line_name)
                    with open ("dogswritecpu.txt", "w") as f2:  # File for CPU names
                        for i in range(Z):
                            line_name = next(f).strip()
                            line_name = line_name + "\n"
                            f2.write(line_name)
dogs()

当前，dogswrite文本文件正在读取，并且每个文本都换行：

Molly
Dave
Tim

我希望文件读为

Molly, 1 , 30, 48, 100

然后换一行。戴夫和蒂姆也是如此。感谢您的所有帮助。

类代码：

class Dog_card_player: #creates the class
    def __init__(self,name):
        self.name = name
        self.exercise = exercise
        self.friendliness = friendliness
        self.intelligence = intelligence
        self.drool = drool

    def Card_stats_player(self): #creates the stats for the card
        print("Name: " + self.name)
        print("Exercise: " + self.exercise)
        print("Friendliness: " + self.friendliness)
        print("Intelligence: " + self.intelligence)
        print("Drool: " + self.drool)

def Printing_card_player():
    with open ("dogswrite.txt") as f1:
        Dog_name_player = Dog_card_player(f1.readline())
        Dog_name_player.Card_stats_player()

import random

s= ', '.join(str(random.randint(1,100)) for i in range(4))

line_name = 'Molly'
line_name =  line_name+', '+s+"\n"
print(line_name) #  f1.write(line_name)

Output:
Molly, 42, 37, 39, 43

random.randint（a，b）返回一个随机整数N，使得a <= N <= b。 randrange（a，b + 1）的别名。

这基本上意味着，如果您的范围是（7,42），那么end并不是排他性的，因为7和42都是包含性的，即它们可以成为结果的一部分。

>>> random.randint(0,1)
1
>>> random.randint(0,1)
0
>>> random.randint(0,1)
1
>>> random.randint(0,1)
1

请勿将其与我们用于for循环的正常范围（开始，结束）混淆，在该范围中，结束是排他的。

>>> list(range(0,1))
[0]
>>> list(range(0,2))
[0, 1]

str.join（可迭代） 返回一个字符串，该字符串是可迭代的字符串的串联。如果存在任何非字符串，则会引发TypeError 可迭代的值，包括字节对象。之间的分隔符 elements是提供此方法的字符串。
