Is there a while(input()) loop in Python 3.x

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

Only in Python 3.8: https://stackoverflow.com/questions/50297704/syntax-and-assignment-expressions-what-and-why — Selcuk, Apr 07 '19 at 23:06
Of course, you can always make the condition `while True:` and then `break` if there's no more input. — Charles Duffy, Apr 08 '19 at 00:03

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.

You can use a for loop instead of a while for in where var is a variable and iterable is a list
