我不明白下面的代码,请帮忙.

它继续针对变量b返回类型不匹配错误.

Dim a As Integer
Dim b As String

a = InputBox("Input the number of items", "Total Number of Items.")
b = InputBox("Which Block?", "Total Number of Items.")

Do While b <> "a" Or "A" Or "B" Or "b"
        MsgBox ("Invalid Block. Try again, Input A or B")
        b = InputBox("Which Block?", "SELECT BLOCK.")
Loop
     If b = "a" Or "A" Then
        Me.ComboBox1.List = Worksheets("Sheet1").Range("a3:a39").Value
    Else
        Me.ComboBox2.List = Worksheets("Sheet2").Range("a3:a35").Value
    End If

我的目标是使用python创建一个空心钻石.

样本输入:

Input an odd Integer:
      9

样本输出:

    *
   * *
  *   *
 *     *
*       *
 *     *
  *   *
   * *
    *

但到目前为止,我有以下代码无法正常工作.请帮我修改代码以实现上述目标:

a=int(input("Input an odd integer: "))

k=1
c=1

r=a

while k<=r:
    while c<=r:
        print "*"
        c+=1

    r-=1
    c=1

    while c<=2*k-1:
        print "*"
        c+=1

    print "\n"
    k+=1

r=1
k=1
c=1

while k<=a-1:
   while c<=r:
       print " "
       c+=1

   r+=1
   c=1

   while c<= 2*(a-k)-1:
       print ("*")
       c+=1

   print "\n"
   k+=1

上面的代码返回的结果离我的目标很远.

Input an odd integer: 7
