Python魔方打乱程序输出存在多余符号问题求助

你的问题出在直接打印列表对象上——Python打印列表时会输出它的原生语法格式，所以会附带方括号、引号和逗号。要得到干净的打乱序列，只需要把列表中的元素用空格拼接成字符串再打印即可。

修改后的代码如下：

import random

notation = ["R","L","F","B","U","D","R'","L'","F'","B'","U'","D'","R2","L2","F2","B2","U2","D2"]
scramble = []
i = 0

while i < 9:
    randomNotation = random.choice(notation)
    scramble.append(randomNotation)
    i += 1
# 用空格拼接列表元素后打印
print(' '.join(scramble))

修改后输出示例：

L2 L R' D' L F2 R D2 L

另外，你也可以简化循环部分，用for _ in range(9)代替while循环，代码会更简洁：

import random

notation = ["R","L","F","B","U","D","R'","L'","F'","B'","U'","D'","R2","L2","F2","B2","U2","D2"]
scramble = [random.choice(notation) for _ in range(9)]
print(' '.join(scramble))
