一旦安装了Pandas,您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其是否正常工作。
import pandas as pd # This is always assumed but is included here as an introduction. import numpy as np importmatplotlib.pyplotas 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信息(均值,标准差等)
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 # dtype: float64
