$$\begin{gather} \mathbf{x} \equiv \sqrt{\frac{\hbar}{m \omega}} \xi = \sqrt{\frac{\hbar}{ \sqrt{k m}}}\xi \\ \beta \equiv \sqrt{\frac{\hbar}{ \sqrt{k m}}} \\ \mathbf{x} \equiv \beta \xi \\ \psi(x) \equiv \psi(\beta \xi) \equiv \phi(\xi) \\ \end{gather}$$
So
$$\begin{gather} -\frac{\hbar^{2}}{2 m} \frac{d^{2}}{d x^{2}} \psi(x)+\frac{1}{2} kx^{2} \psi(x)=E \psi(x) \\ \end{gather}$$

could be rewrite as

$$\begin{gather} -\frac{\hbar^{2}}{2 m \beta^2} \frac{d^{2}}{d \xi^{2}} \phi(\xi)+\frac{1}{2} k\beta^2\xi^{2} \phi(\xi)=E \phi(\xi) \\ -\frac{\hbar^{2}}{2 m \frac{\hbar}{ \sqrt{k m}} } \frac{d^{2}}{d \xi^{2}} \phi(\xi)+\frac{1}{2} k \frac{\hbar}{ \sqrt{k m}} \xi^{2} \phi(\xi)=E \phi(\xi) \\ -\frac{\hbar}{2} \sqrt{\frac{k}{m}} \frac{d^{2}}{d \xi^{2}} \phi(\xi)+\frac{\hbar}{2} \sqrt{\frac{k}{m}} \xi^{2} \phi(\xi)=E \phi(\xi) \\ -\frac{\hbar \omega}{2} \frac{d^{2}}{d \xi^{2}} \phi(\xi)+\frac{\hbar \omega}{2} \xi^{2} \phi(\xi)=E \phi(\xi) \\ \end{gather}$$

#### Python copy.copy() vs copy.deepcopy()

example

>>> a = [1, 2, ]
>>> b = copy.copy(a)
>>> c = copy.deepcopy(a)
>>> a[-1] = 4

results

>>> a
[1, 2, ]
>>> b
[1, 2, ]
>>> c
[1, 2, ]
