pandas Series

list crate series

from pandas import Series
a=[1,2,3,4]
s=Series(a) #create series 系統自行創建index
s.index
s.values

自行設定index
s1=Series(a,index=[‘A’,’B’,’C’,’D’])

array creat series

import numpy as np
s2=Series(np.arange(5))

dict creat series

d={‘A’:1,’B’:2,’C’:3,’D’:4}
s3=Series(d) #index = dic key

series 轉換成 dict

s3.to_dict()

Series操作

s3[‘A’] #訪問
s3[s3>2]
s3.max()
s3.min()
s3.pop(‘A’)
