Python 打印右箭头数字图案程序

编写一个 Python 程序，使用 for 循环打印右箭头数字图案。

rows = int(input("Enter Right Arrow Number Pattern Rows = "))

print("====Right Arrow Number Pattern====")

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

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

这个 示例 程序使用 while 循环打印数字组成的右箭头图案。

rows = int(input("Enter Rows = "))

print("====Right Arrow Number Pattern====")
i = 1

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

i = 2
while(i < rows ):
    j = 1
    while(j <= rows):
        if j < rows - i:
            print(end = '  ')
        else:
            print(j, end = ' ') 
        j = j + 1
    print()
    i = i + 1

Enter Rows = 8
