Hello World

一旦安装了 Pandas，你可以通过创建随机分布值的数据集并绘制其直方图来检查它是否正常工作。

import pandas as pd  # This is always assumed but is included here as an introduction.
import numpy as np
import matplotlib.pyplot as plt

np.random.seed(0)

values = np.random.randn(100) # array of normally distributed random numbers
s = pd.Series(values) # generate a pandas series
s.plot(kind='hist', title='Normally distributed random values') # hist computes distribution
plt.show()

检查一些数据的统计数据（平均值，标准偏差等）

s.describe()
# Output: count    100.000000
# mean       0.059808
# std        1.012960
# min       -2.552990
# 25%       -0.643857
# 50%        0.094096
# 75%        0.737077
# max        2.269755
