1.1 Series in Pandas

1.1 Series in Pandas

Pandas:

Pandas is a Python Library. Pandas stands for “Panel Data System”

Series:

Series is a data structure. Which can store 1 D homogeneous data.

DataFrame:

DataFrame is a 2 D Data Structure, which can store 2 D Heterogeneous data.

Series	Data Frame
Series is a data structure	Data is a data structure
Series is 1 Dimensional	DataFrame is 2 Dimensional
Series is Homogeneous	DataFrame is Heterogeneous
Value Mutable	Value Mutable
Size Immutable	Size Mutable

 

 

How To create:

1.       Using Python Sequence (List, Tuple, String)

2.       Using ndarray

3.       Using Python Dictionary

4.       Using Scalar Value
