Javascript代码：

function rstr2binl(d) {
    for (var a = Array(d.length >> 2), b = 0; b < a.length; b++) {
        a[b] = 0;
    }

    for (b = 0; b < d.length * 8; b += 8){
        a[b >> 5] |= (d.charCodeAt(b / 8) & 255) << b % 32;
    }
    return a
}

Python代码：

def rstr2binl(d):
    a = [0] * (len(d) >> 2)
    for b in range(0, len(a), 1):
        a[b] = 0

    for b in range(0, len(d) * 8, 8):
        a[b >> 5] |= (ord(d[b / 8]) & 255 << b) % 32

    return a

rstr2binl("abc123456")

Python输出:Error list out of range
JS输出:[ 828596833, 892613426, 54 ]

在JS代码中有些步骤是用 undefined |= (d.charCodeAt(b / 8) & 255) << b % 32;
请问在Python中如何实现呢，或者有其他办法达到这个函数的功能吗
