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:
