Python 打印倒 V 形星形图案程序

使用 for 循环编写一个 Python 程序，用于在正方形星形图案内打印倒 V 形星形图案或半菱形。

rows = int(input("Enter Inverted V Star Pattern Rows = "))

print("====The Inverted V Star Pattern====")

for i in range(rows, 0, -1):
    for j in range(1, i + 1):
        print('*', end = '')
    for k in range(1, 2 * (rows - i) + 1):
        print(end = ' ')
    for l in range(1, i + 1):
        print('*', end = '')
    print()

此程序使用 while 循环显示星形的倒 V 形图案。

rows = int(input("Enter Inverted V Star Pattern Rows = "))

print("====The Inverted V Star Pattern====")
i = rows

while(i >= 1):
    j = 1
    while(j <= i):
        print('*', end = '')
        j = j + 1
    k = 1
    while(k <= 2 * (rows - i)):
        print(end = ' ')
        k = k + 1
    l = 1
    while(l <= i):
        print('*', end = '')
        l = l + 1
    print()
    i = i - 1

Enter Inverted V Star Pattern Rows = 9
====The Inverted V Star Pattern====

在此 Python 模式 示例 中，我们创建了一个函数，允许输入任何字符并打印给定字符的倒 V 形。

def InvertedVStar(i, ch):
    for j in range(1, i + 1):
        print('%c' %ch, end = '')

rows = int(input("Enter Inverted V Star Pattern Rows = "))

ch = input("Symbol to use in V Pattern = " )

print("====The Inverted V Star Pattern====")

for i in range(rows, 0, -1):
    InvertedVStar(i, ch)
    for k in range(1, 2 * (rows - i) + 1):
        print(end = ' ')
    InvertedVStar(i, ch)
    print()

Enter Inverted V Star Pattern Rows = 14
Symbol to use in V Pattern = #
====The Inverted V Star Pattern====
