Python 3.x 中是否有 while(input()) 循环

Question

I am trying to write a python solution to How many digits on Kattis which requires a while(input()) loop I have a C++ solution using

int n;
while( cin >> n ) {}

but I was wondering if there was a way to do this in python 3.x

Answer 1

I usually code it like this:

try:
    while True:
        n = int(input())
        ...
except EOFError:
    pass

Once there is no more input to read, the input() call will throw an EOFError and exit the loop.

Answer 2

你可以使用 for 循环而不是 while for in where var 是一个变量，iterable 是一个列表
