python如何输出星号组成的菱形图形？

def printStar(intNum):

  s = "*"

  spaceLength = intNum

  blockCount = int(intNum/2+1)

  for i in range(spaceLength):

    result = s.rjust(blockCount)

    if i >= int(spaceLength/2):

      print(result)

      s = s[2:]

      blockCount -= 1

    else:

      print(result)

      s = s+(2*"*")

      blockCount += 1

def oddOReven(intNum):

  if intNum%2 == 0:

    print("please input a odd num data")

  else:

    printStar(intNum)

if __name__ == '__main__':

  while True:

    try:

      intNum = eval(input("please input a odd num data\n"))

      oddOReven(intNum)

    except BaseException as e:

      print("Please input as 1/2/3... Errorcode:%s" % e)
