Python pandas: Series
Series is a one dimensional labeled array whose elements can be any data type. In a
DataFrame (which is two dimensional), each column's data is stored in a
Series object.
import pandas
ser = pandas.Series([1,'two', {"num": 42, "txt": "hello world"}], index = ['a', 'b', 'c'])
print(ser.b ) # two
print(ser.c['txt']) # hello world
The number of labels (index) must correspond to the number of items in the series. The following statement throws the ValueError Length of values (6) does not match length of index (3) :
ser = pandas( [7, 2, 3, 8, 4, 5], index = ['a', 'b', 'c'])
A series can be created from a dict:
ser = pandas.Series( {'num': 42, 'txt': 'Hello world'} )
