python的数据类型有哪些?
python的数据类型：1. 数字类型，包括int（整型）、long（长整型）和float（浮点型）。2.字符串，分别是str类型和unicode类型。3.布尔型，Python布尔类型也是用于逻辑运算，有两个值：True（真）和False（假）。4.列表，列表是Python中使用最频繁的数据类型，集合中可以放任何数据类型。5. 元组，元组用”()”标识，内部元素用逗号隔开。6. 字典，字典是一种键值对的集合。7. 集合，集合是一个无序的、不重复的数据组合。
# 创建六个面，放在faces列表里，顺序为上（0），下（1），左（2），右（3），前（4），后（5）faces = [np.zeros((3, 3))]for i in range(1, 6): faces.append(np.ones((3, 3)) + faces[i - 1])
每一个面的 顺时针 和 逆时针 旋转由函数 clockwise() 和 antiClockwise() 实现
t = np.array([[0, 0, 1], [0, 1, 0], [1, 0, 0]])# 该面顺时针旋转 90 度def clockwise(face): face = face.transpose().dot(t) return face# 该面逆时针旋转 90 度def antiClockwise(face): face = face.dot(t).transpose() return faceA.transpose() 方法是实现 A 矩阵的转置
A.dot(B) 方法是实现 A乘以矩阵B
通过计算，上述方法可以实现矩阵顺时针或者逆时针旋转的效果
在这里以左面的顺时针旋转 90°为例，其它旋转方式可以类比
def L(FACES): FACES[2] = clockwise(FACES[2]) FACES_new = cp.deepcopy(FACES) a, b, c, d = clockwise(FACES_new[4]), clockwise(FACES_new[1]), antiClockwise(FACES_new[5]), clockwise(FACES_new[0]) e, f, g, h = cp.deepcopy(a), cp.deepcopy(b), cp.deepcopy(c), cp.deepcopy(d) e[0], f[0], g[0], h[0] = d[0], a[0], b[0], c[0] FACES[4], FACES[1], FACES[5], FACES[0] = antiClockwise(e), antiClockwise(f), clockwise(g), antiClockwise(h)直接调用函数将左面（第2面）顺时针旋转 90°
FACES[2] = clockwise(FACES[2])这里采用深度复制，使用 cp.deepcopy() 的方法，避免直接使用等号 ‘=' 导致不同的变量指向同一个值。这时，【e、f、g、h】和【a、b、c、d】代表魔方的
【正面、底面顺时针旋转90°、背面逆时针旋转90°、上面顺时针旋转90°】
a, b, c, d = clockwise(FACES_new[4]), clockwise(FACES_new[1]), antiClockwise(FACES_new[5]), clockwise(FACES_new[0])旋转的目的是：
在左面旋转的过程中，左面会影响到其它四个面，但对其它四个面的影响是不同的。例如正面、底面和上面被影响的是第一列，而背面被影响的是第三列。我们为了使各面统一起来，方便数值的改变，我们选择将正、底、上面顺时针旋转90°，将背面逆时针旋转90°。这时，我们只需按顺序交换每一面的第一行，最后再逆时针或顺时针转回来即可。
按顺序交换：正面第一行传递到底面第一行
上面第一行传递到正面第一行
背面第一行传递到上面第一行
底面第一行传递到背面第一行
e[0], f[0], g[0], h[0] = d[0], a[0], b[0], c[0]最后再依次根据上述操作逆旋转回去：
FACES[4], FACES[1], FACES[5], FACES[0] = antiClockwise(e), antiClockwise(f), clockwise(g), antiClockwise(h)代码
