将用户输入追加到循环列表中 [英] Appending user input to a list in a loop

问题描述

我是python编程的新手，并且正在做一些实验.希望我的问题不是很愚蠢:我正在编写一个小程序，将输入添加到列表中，并在输入等于4时使用while循环将其打印出来.问题是它永远不会停止添加输入并打印列表. 我的代码是:

I'm new to python programming and I'm doing some experiments with it. Hoping my question is not too silly: I'm writing a little program that adds inputs to a list and print it when the input equals to 4, using a while loop. the problem is it never stops to add inputs and print the list. My code is:

S=input()
L=[]
while S!=4:
    L.append(S)
    if S==4:
        break
print(L)

推荐答案

您已在代码中创建了一个无限循环.进入循环后，您无需更改S的值.您应该像这样从循环内部添加获取另一个输入:

You've created an infinite loop in your code. You're not changing the value of S after you enter the loop. You should add get an another input from inside the loop like so:

S=input()
L=[]
while S!=4:
   L.append(S)
   S = input()
print(L)

此外，代码中的if条件是无用的，因为它已经在while循环声明中设置了

In addition, The if condition in your code is useless since It's already set in the while loop declaration
