這就是我需要的，我很感激伙計們

Answer 1

首先你必須學習如何打印 python 金字塔你可以從這個鏈接學習它，然后在你可以理解下面的代碼之后嘗試理解它

space = '\t'
star = '*'

size = int(input("Enter number to make triangle: \n"))

def printRow(current_row, max_row) :
    rPri = 0
    lefNum = 0
    star_count = 2*current_row - 3
    if current_row == 1:
      lefNum = 1
    if current_row > 1:
      lefNum = (current_row-1)*2
      rPri = 1
    rigNum = lefNum + 1
    line = space * (max_row - current_row) + str(lefNum) +  (space + star) * star_count + (space + str(rigNum))*rPri
    print(line)

if size<=0 :
    print("The value you entered is too small to display a triangle")

for i in range(1, size+1) :
    printRow(i, size)

Answer 2

對於此類問題，請嘗試將 output 與其索引（或在本例中為current_row ）相關聯。 此外，似乎最好從 0 開始。

0:                                   1
1:                           2       *       3
2:                   4       *       *       *       5
3:           6       *       *       *       *       *       7
4:   8       *       *       *       *       *       *       *       9

max_row為 5， current_row為 0 到 4。
每行有max_row - current_row - 1空格。
每行有2 * current_row - 1顆星。
左邊的數字是current_row的兩倍，或2 * current_row 。 除了 0 之外的所有情況都是如此。對於這種特殊情況，我們可以使用 if 語句。
右邊的數字就是left + 1或2 * current_row + 1 。

space = '\t'
star = '*'
size = int(input("Enter number to make triangle: "))

def printRow(current_row, max_row) :
    star_count = 2 * current_row - 1

    line = space * (max_row - current_row - 1)

    if current_row == 0 :
        line += "1"
    else :
        line += str(2 * current_row) + space

    line += (star + space) * star_count

    if current_row > 0 :
        line += str(2 * current_row + 1)

    print(line)

if size <= 0 :
    print("The value you entered is too small to display a triangle")

for i in range(0, size) :
    printRow(i, size)
