空格改成空字符串

Because you're checking a space, not an emply string in your code, which will be an endless loop.
Consider to change ' ' (space) in the if sentence to '' (emply) to stop that.

给写了两种方法：

s = 0
while True:
    n = input()
    if not n:  #即： if n=='':
        break
    s += int(n)
print(s)

#或者：
s = 1
while s:
    try:
        s += int(input())
    except:
        print(s-1)
        break
