python輸出菱形(python輸出菱形星號的方法)

讀入一個整數N,N是奇數,輸出由星號字符組成的菱形三角形,要求:????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

第1行1個星號,第2行3個星號,第3行5個星號,依次類推,最后n/2共n個星號,然后在依次遞減到n行為一個星號。????????????????????????????????

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)
