我是靠谱客的博主孤独御姐，最近开发中收集的这篇文章主要介绍python输入0则结束程序,我如何通过在python 3中结束文件来终止输入，觉得挺不错的，现在分享给大家，希望可以做个参考。

The code I am working on is a simple subtraction work but my problem arises when I need to end the inputs.

The problem tells me that the input is terminated by end of file and I have no idea what that means when the question has any number of inputs.

while(True):

data=[]

data= list(map(int,sys.stdin.readline().split()))

if (data[1]>data[0]):

total=data[1]-data[0]

else:

total=data[0]-data[1]

print(total)

How do I change this code to allow it to end without the user inputting anything

解决方案

As suggested in comments, use loop over sys.stdin. I've also added some other improvements:

for line in sys.stdin:

data = [int(x) for x in line.split()]

total = abs(data[1] - data[0])

print(total)
