Data Structure
Pandas library implements mainly two data structures: Series and DataFrame
1) Series :
Series is one-dimensional labeled array capable of holding any data type such as integers, strings, floating-point numbers, Python objects, etc. A Series accepts three types of input:
- a Python dict
- an ndarray
- a scalar value (like 5)
2) DataFrame :
DataFrame is a 2-dimensional labeled data structure with columns of different types. DataFrame is the most widely used data structure. A DataFrame can accept many kinds of input:
- Dict of 1D ndarrays, lists, dicts, or Series
- 2-D numpy.ndarray
- Structured or record ndarray
- ASeries
- Another DataFrame
