Python 打印加号星型图案程序

编写一个 Python 程序，使用 for 循环打印加号星型图案。在此 Python 示例中，两个 for 循环都将从 1 遍历到 2 * rows。if 语句会检查 i 或 j 是否等于 rows，如果条件有效，则打印星号。

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

print("Plus Star Pattern") 

for i in range(1, 2 * rows):
    for j in range(1, 2 * rows):
        if i == rows or j == rows:
            print('*', end = '')
        else:
            print(' ', end = '')
    print()

Python 使用 while 循环打印加号星型图案的程序。

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

print("Plus Star Pattern") 

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

Enter Plus Pattern Rows = 7
Plus Star Pattern
      *      
      *      
      *      
      *      
      *      
      *      
*************
      *      
      *      
      *      
      *      
      *      
      *

在此 Python 程序中，plusPattern 函数打印给定符号的加号图案。

# Python Program to Print Plus Star Pattern
 
def plusPattern(rows, ch):
    for i in range(1, 2 * rows):
        for j in range(1, 2 * rows):
            if i == rows or j == rows:
                print('%c' %ch, end = '')
            else:
                print(' ', end = '')
        print()

rows = int(input("Enter Plus Pattern Rows = "))
ch = input("Symbol to use in Plus Pattern = " )

print("Plus Pattern") 
plusPattern(rows, ch)

Enter Plus Pattern Rows = 8
Symbol to use in Plus Pattern = $
Plus Pattern
       $       
       $       
       $       
       $       
       $       
       $       
       $
