Python脚本输出根据我使用的计算机而变化

Question

我遇到了一些奇怪的问题，同一个脚本输出的结果不同。相同的python版本，相同的库

Lat=((INPUT_FILE[location[i]+OFFSET+4])<<24|
     (INPUT_FILE[location[i]+OFFSET+5])<<16|
     (INPUT_FILE[location[i]+OFFSET+6])<<8|
     (INPUT_FILE[location[i]+OFFSET+7])<<0)/11930464.71
Long=((INPUT_FILE[location[i]+OFFSET+0])<24|
      (INPUT_FILE[location[i]+OFFSET+1])<16|
      (INPUT_FILE[location[i]+OFFSET+2])<<8|
      (INPUT_FILE[location[i]+OFFSET+3])<<0)/11930464.71
print(Long)

基本上，我所做的就是从文件中读取字节，然后用数学将它们转换成坐标。在Windows计算机上，它被正确地解释为2补负数，而在Linux计算机上，它输出的值就好像它只是一个无符号数一样。好像是个Q字D字的问题
