Python:多个 if 条件取决于参数

Question

我遇到以下问题。我有一个参数 frc_size。根据 fcr_size 的大小，必须在 if 条件中检查更多距离。有没有一种方法可以巧妙地处理并缩短所有这些表达式？例如，对于 fcr_size = 3，if 条件如下所示:

minusscore = 2

for coords in full_box:
    mindist = float("inf")
    for m in range(len(lineSegmentPairs[0])):
        newdist = dist(lineSegmentPairs[0][m], lineSegmentPairs[1][m], coords)
        if newdist<mindist:
            mindist=newdist
    if mindist <= radius :
        val1 = int(sparse1.get(coords,"0")[0]) - minusscore
        sparse1[coords] = [str(val1)]
    elif mindist <= (radius +1) :
        val1 = int(sparse1.get(coords,"0")[0]) + 3
        sparse1[coords] = [str(val1)]
    elif mindist <= (radius +2) :
        val1 = int(sparse1.get(coords,"0")[0]) + 2
        sparse1[coords] = [str(val1)]
    elif mindist <= (radius +3) :
        val1 = int(sparse1.get(coords,"0")[0]) + 1
        sparse1[coords] = [str(val1)]
    elif mindist > (radius +3) :
        continue

但如果 fcr_size 为 4，则需要附加 if 条件，例如:

minusscore = 2

for coords in full_box:
    mindist = float("inf")
    for m in range(len(lineSegmentPairs[0])):
        newdist = dist(lineSegmentPairs[0][m], lineSegmentPairs[1][m], coords)
        if newdist<mindist:
            mindist=newdist
    if mindist <= radius :
        val1 = int(sparse1.get(coords,"0")[0]) - minusscore
        sparse1[coords] = [str(val1)]
    elif mindist <= (radius +1) :
        val1 = int(sparse1.get(coords,"0")[0]) + 4
        sparse1[coords] = [str(val1)]
    elif mindist <= (radius +2) :
        val1 = int(sparse1.get(coords,"0")[0]) + 3
        sparse1[coords] = [str(val1)]
    elif mindist <= (radius +3) :
        val1 = int(sparse1.get(coords,"0")[0]) + 2
        sparse1[coords] = [str(val1)]
    elif mindist <= (radius +4) :
        val1 = int(sparse1.get(coords,"0")[0]) + 1
        sparse1[coords] = [str(val1)]
    elif mindist > (radius +4) :
        continue

Answer 1

也许是这样的？

if mindist <= radius:
  val1 = int(sparse1.get(coords,"0")[0]) - minusscore
  sparse1[coords] = [str(val1)]
elif mindist > (radius + fcr_size):
  continue
else:
  for i in range(fcr_size):
    if mindist <= radius + i + 1:
      val1 = int(sparse1.get(coords,"0")[0]) + (fcr_size - i)
      sparse1[coords] = [str(val1)]
      break
