Python程序打印空心半菱形星形图案

编写一个Python程序，使用for循环打印空心半菱形星形图案。if语句检查i是否等于j，或者j是否等于零或一，如果为真则打印星号；否则打印空格。

# Python Program to Print Hollow Half Diamond Star Pattern
 
rows = int(input("Enter Hollow Half Diamond Pattern Rows = "))

print("Hollow Half Diamond Star Pattern") 

for i in range(0, rows):
    for j in range(0, i + 1):
        if i == j or j == 0:
            print('*', end = '')
        else:
            print(' ', end = '')  
    print()

for i in range(rows - 1, 0, -1):
    for j in range(1, i + 1):
        if i == j or j == 1:
            print('*', end = '')
        else:
            print(' ', end = '')  
    print()

此Python程序使用while循环打印空心半菱形星形图案。

# Python Program to Print Half Diamond Star Pattern
 
rows = int(input("Enter Hollow Half Diamond Pattern Rows = "))

print("Hollow Half Diamond Star Pattern") 
i = 0
while(i < rows):
    j = 0
    while(j <= i):
        if i == j or j == 0:
            print('*', end = '')
        else:
            print(' ', end = '')
        j = j + 1
    i = i + 1
    print()

i = 1
while(i < rows):
    j = i
    while(j < rows):
        if i == j or j == rows - 1:
            print('*', end = '')
        else:
            print(' ', end = '') 
        j = j + 1
    i = i + 1
    print()

Enter Hollow Half Diamond Pattern Rows = 8

在此Python示例中，我们创建了一个hollowHalfDiamond函数来打印空心半菱形图案。它用给定的符号替换空心半菱形中的星号。

# Python Program to Print Hollow Half Diamond Star Pattern

def hollowHalfDiamond(rows, ch):
    for i in range(rows):
        for j in range(0, i + 1):
            if i == j or j == 0:
                print('%c' %ch, end = '')
            else:
                print(' ', end = '') 
        print()

    for i in range(1, rows):
        for j in range(i, rows):
            if i == j or j == rows - 1:
                print('%c' %ch, end = '')
            else:
                print(' ', end = '') 
        print()

rows = int(input("Enter Hollow Half Diamond Pattern Rows = "))

ch = input("Symbol to use in Hollow Half Diamond Pattern = " )

print("Hollow Half Diamond Star Pattern")

hollowHalfDiamond(rows, ch)

Enter Hollow Half Diamond Pattern Rows = 10
