python for循环怎么改成whlie循环 加注释

size = int(input("请输入棋盘的大小："))
for i in range(size):                    
    for j in range(size):               
        if i == 0 and j == 0:           
            print("┏",end='')
        elif i == 0 and j == size - 1:  
            print("┓",end='')
        elif i == size - 1 and j == 0: 
            print("┗",end='')
        elif i == size - 1 and j == size - 1: 
            print("┛",end='')
        elif j == 0:        
            print("┠",end='')
        elif i == size - 1:     
            print("┷",end='')
        elif j == size - 1:    
            print("┨",end='')
        elif i == 0:          
            print("┯",end='')
        else:                   
            print("┼",end='')
    print('')                

i = 1
while True:
执行命令
i = i+1
if i == size:
break
else:
continue
以上代码的意思就是while True:然后在循环体里执行命令，循环外先定义一个i=1，在循环里不断的增加i的值，直到i的值和size的值相等时退出循环体，否则继续执行，for 循环的本质遍历数据，而你在while叠加i值的过程中其实相当于遍历range(size)中的所有值，形成的循环效果是一样的
