翻译C++；将char类型用于Python的代码

这段代码在python中是什么样子的

nrcom1->SendChar

可以替换为

serial.write（A_CHAR）

---

它看起来像这样（不是一个工作示例，只是为了让您开始）：

更新：提供了如何使示例工作的提示

def prepare():
    temp = "%04XT2000A" % 76
    send(temp)


def send(tx_string):
    checksum = 0x02
    serial.write(checksum)

    # hint: int conversion will not work since tx_string is a
    # string representation of a hex value, add conversion code for this
    while(tx_string):
        serial.write(int(tx_string[0]))
        checksum = checksum ** int(tx_string[0])
        tx_string = tx_string[1:]

    serial.write(0x03)
    checksum = checksum ** 0x03
    serial.write(checksum)

我得到的“int”对象不是iterableOn什么线？我没有说这是一个有效的例子，我没有测试它，它只是一个草稿，让你自己思考。但我想我是用勺子喂的。。。再努力一点。

def prepare():
    temp = "%04XT2000A" % 76
    send(temp)


def send(tx_string):
    checksum = 0x02
    serial.write(checksum)

    # hint: int conversion will not work since tx_string is a
    # string representation of a hex value, add conversion code for this
    while(tx_string):
        serial.write(int(tx_string[0]))
        checksum = checksum ** int(tx_string[0])
        tx_string = tx_string[1:]

    serial.write(0x03)
    checksum = checksum ** 0x03
    serial.write(checksum)
