30秒学会 Python 片段 – Map number to range

Maps a number from one range to another range.

• Return num mapped between outMin–outMax from inMin–inMax.

代码实现

def num_to_range(num, inMin, inMax, outMin, outMax):
  return outMin + (float(num - inMin) / float(inMax - inMin) * (outMax
                  - outMin))

使用样例

num_to_range(5, 0, 10, 0, 100) # 50.0
