How add random numbers to a text file

I am trying to add numbers that are randomly generated into my text file as i read a name from one file into another. Here is my code:

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()

Currently the dogswrite text file reads with each being on a new line:

Molly
Dave
Tim

I want to the file to read as 

Molly, 1 , 30, 48, 100

then a new line. The same happens to Dave and Tim. Thanks for all the help.

Class Code:

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) Return a random integer N such that a <= N <= b. Alias for randrange(a, b+1).

What it basically means is that here end is not exclusive if your range is (7,42) both 7 and 42 are inclusive ie they can be part of result.

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

don't confuse it with normal range(start, end) that we use with for loop, in which end is exclusive.

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


str.join(iterable) Return a string which is the concatenation of the strings in iterable. A TypeError will be raised if there are any non-string values in iterable, including bytes objects. The separator between elements is the string providing this method.
