To draw the normal curve, we need to use the `norm.pdf(~)` method of the `scipy.stats` library:

``` from scipy.stats import normdef draw_normal(mean=0, std=1): x = np.linspace(mean-4*std, mean+4*std, 1000) plt.title("Normal Curve") plt.xlabel("x") plt.plot(x, norm.pdf(x, loc=mean, scale=std)) plt.ylim(bottom=0) ```

To draw a standard normal distribution:

``` draw_normal() ```

The output is as follows:

To draw a normal distribution with mean 5 and standard deviation 2:

``` draw_normal(5, 2) ```

The output is as follows:
