Copy

import numpy as np
import matplotlib.pyplot as plt 

x = np.arange(-4, 4, 0.01)
y = (lambda x: 1/np.sqrt(2*np.pi)/np.exp(x**2/2))(x)
plt.plot(x, y)
plt.show()

Python

Copy

import numpy as np
import matplotlib.pyplot as plt 

m = 0
s = 1

x = np.linspace(m-3*s, m+3*s, 100)
y = (lambda x: 1/(s*(2*np.pi)**.5) * np.exp(-(x-m)**2/(2*s**2)))(x)
plt.plot(x, y)

Python

Copy

import numpy as np
from scipy.stats import norm
import matplotlib.pyplot as plt

m = 0
s = 1

x = np.linspace(m-3*s, m+3*s, 100)
y = norm.pdf(x, m, s)
plt.plot(x, y)
