python 根据指定字符串和边长打印正方框

方法1：

def cube():
    number=int(input("输入边长:n"))
    str_msg=input("输入要打印的字符:n")
    msg=str_msg+('t'+str_msg)*(number-1)
    msg_centre=str_msg+'t'*(number-1)+str_msg
    print(msg)
    for x in range(number-2):
        print(msg_centre)
    print(msg)
#cube()

方法2:

def cubeone():
    number = int(input("输入边长:n"))
    str_msg = input("输入要打印的字符:n")
    for x in range(number):
        if x==0:
            print(str_msg+('t'+str_msg)*(number-1))
        elif x==(number-1):
            print(str_msg+('t'+str_msg)*(number-1))
        else:
            print(str_msg + ('t') * (number - 1)+str_msg)
#cubeone()

运行结果：
