python两个字符串有变化值作对比

两个字符串作对比，实际值一些no变化，预期值中用*代替，以下是脚本

actual = '{"Status": 1, "Content": {"order_no": "20190813173142658002396779806585", "request_id": "4999870244479602310", "status": "SUCCESS"}, "Message": "请求成功"}'
expect = '{"Status": 1, "Content": {"order_no": "*", "request_id": "*", "status": "SUCCESS"}, "Message": "请求成功"}'

count = 0
for expect_char in expect:
    count += 1
    if expect_char == '*':  # 遍历预期字符串，找到*位置
        print(count)
        actual = actual[:count - 1] + "*" + actual[count:]  # 把实际字符串该位置替换为*
        print(actual)
        for actual_char in actual[count:]:
            if actual_char == '"':  # 依次替换后面的字符为空，直到引号,引号可以换为其他字符，亦可多个
                break
            actual = actual[:count] + actual[count + 1:]
            print(actual, count)

print(actual)

因为对性能要求不高，想提高性能，可替换字符串拼接方式。
