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

from scipy.stats import norm

def 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:
