如何用Python从文件中将数字转换为整数

Question

Assume that a file containing a series of integers is named numbers.txt. Write a program that calculates the average of all the numbers stored in the file.

上面是我必须写的程序，这里是我到目前为止的代码下面是我写的代码。有没有一种方法我可以编码，这样不管文件中有多少个数字，它都能工作。在

infile = open('numbers.txt', 'r')
num1 = int(infile.readline())
num2 = int(infile.readline())
num3 = int(infile.readline())
num4 = int(infile.readline())
num5 = int(infile.readline())
num6 = int(infile.readline())
num7 = int(infile.readline())
num8 = int(infile.readline())
num9 = int(infile.readline())
num10 = int(infile.readline())
infile.close()

total = num1+num2+num3+num4+num5+num6+num7+num8+num9+num10

a = total/10

print (a)

Answer 1

loop_count = 0
total = 0
data = open("numbers.txt","r")
for line in data.readlines():
    total = total + int(line)
    loop_count += 1
avg = total/loop_count

现在请学习做你自己的家庭作业。在
