如何在cli脚本中获取多个输入行

python script.py input1 input2 input3

import argparse

parser = argparse.ArgumentParser()
parser.add_argument('inputs', nargs='+', help='input lines')
args = parser.parse_args()

for line in args.inputs:
    print(line)

python script.py < input.txt

import sys

for line in sys.stdin:
    line = line.strip()
    print(line)

while True:
    line = input("Enter a line (or 'q' to quit): ")
    if line == 'q':
        break
    print(line)
