Python打印“菱形”星号代码方法

本人是一名python初学者，刚刚看到一道有趣的python问题，“用python如何在编译器中打印出菱形图案？”
因此决定尝试一下，代码不多，仅供参考。

代码

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)

运行结果：
