1.

Import NumPy as Np;import pandas as Pdvalues = PD. Series (Np.random.normal (0,1,size=2000))

#Series可看作一个定长的有序字典.

The probability density function corresponding to the Gaussian distribution corresponds to the numpy:

Np.random.normal (Loc=mu, Scale=sigma, Size=non) standard normal distribution (mu=0,sigma=1) np.random.normal (loc=0, scale=1, Size=non) Values.hist (bins=100, alpha=0.3, color= ' K ', normed= True) #bins interval number alpha Transparency normed=true parameter to regularization histogram
