### python使用字符串构建stdin对象 ###

\{不知道有没有其它更好的方法\}

python直接在代码中读入字符串到stdin中

import sys, io, re
    
    sys.stdin = io.StringIO('''4,6
    8 9 6 5
    9,7
    8,5
    8,4
    9,3
    7,3
    7,2
    ''')
    a = []
    while True:
        try:
            ai = input()
            a.append(ai)
        except:
            break
    print(a)

或者input()一下就调用一下写好的程序！

Note: 如果是python2则字符串要是unicode，即io.StringIO(u'''\*\*\*\*\*\*\*''')
