无符号字符数组问题 我有一个C++代码，它移位一个字体。我正在尝试用Python代码来做同样的事情。谢谢你的帮助。 我正在重新编写我的问题，以便将其简化为我认为需要的内容。 非常感谢你们的时间和指示 在C++中，我可以创建： unsigned char vals[8][8] = {0};

这给了我一个8 X 8的数组，里面填充了0。。。表示VAL[0][0]的{0}

而数组将转到VAL[7][7]

---

在我的C++代码中，我用位元值填充了VARS数组，然后我移值

你可能想使用<代码> NoMPy < /C>和指定类型的NDAREL——例如

import numpy as np

np.full(shape=8, fill_value=0, dtype=np.int8) # or np.zeros()

---

与默认的Python

int

处理相反（正如iBug在评论中指出的那样，它是无限长的），您将得到一个非常特定位长度的整数值。转换这些函数将给你类似C++的行为。

python整型的长度是无限的。我不完全确定我理解这个问题，但大概你只需要和你的值一起使用<代码> 0xFF，例如：GC:Cal= VALV[i] [j]和0xFF谢谢。艾伦，C++中的数组VALL填充了位字体值，即[0x00，0x3C，0x66，0x06，0x0C，0x30，0x60，0x7E]，[0x00，0x3C，0x66，0x1C，0x06，0x66，0x3C]，[0x00，0x0C，0x1C，0x2C，0x4C，0x7E，0x0C，0x0C]，[0x00，0x7E，0x60，0x7C，0x06，0x66，0x3C]，[0x00，0x3C，0x66，0x60，0x7C，0x66，0x3C]，[0x00，0x7E，0x18，0x18]，[0x00，0x3C，0x66，0x66，0x3C，0x66，0x66，0x66，0x3C]，轮班更新了，请提取一个。所有用来挑出你误解的代码都没有用。这会使这成为一个糟糕的问题，甚至是离题。乌尔里奇，我更新了我的问题…我希望更容易理解。谢谢。我认为并希望它是最小的、完整的和可验证的。谢谢sophros，我将尝试一下。你好sophros！这看起来很有效，我相信numpy数组正在返回正确的值！现在我需要将所有这些都合并到我的Python中，我很乐观！感谢您的帮助和洞察力。
