求变量

Question

我正在尝试读取.txt文件并在一行上输出打印。 .txt文件写入了随机整数。我的代码会写入这些数字，但不会将它们写在同一行。我也试图找到这些整数的总和并打印出来。我不确定我的代码有多近，但我现在卡住了。任何帮助将不胜感激。

def main():
    # Open a file for reading.
    infile = open('numbers.txt', 'r')
    file_contents = infile.read()
    infile.close()
    total = (sum,file_contents)
    print(file_contents,'\n',end='')
    print(total)

main()

以下是编写numbers.txt文件的代码（如果有帮助的话）

import random

def main():
    nums = open('numbers.txt','w') #Opens and assigns numbers.txt
    #Generates integer random integer between 4 and 7
    file_size = random.randint(4, 7) 
    #Takes the file_size integer and generates that amount
    #of random integers between 5 and 19. 
    for num in range(file_size):
       random_num = random.randrange(5,20,2)
       if random_num % 2 ==1:
           nums.write(str(random_num)+'\n')
    nums.close()
    print('Data has been written.')

main()

我已经更新了代码，但遗憾的是没有运气。

    def main():
    # Open a file for reading.

    infile = open('numbers.txt', 'r')



    file_contents = infile.read()

    total += sum(int(file_contents.strip()))





    infile.close()

    print(file_contents)
    print(total)






main()
