When doing data analysis, it is important to make sure you are using the correct data types; otherwise you may get unexpected results or errors. In the case of pandas, it will correctly infer data types in many cases and you can move on with your analysis without any further thought on the topic. Despite how well pandas works, at some point in your data analysis processes, you will likely need to explicitly convert data from one type to another. This article will discuss the basic pandas data types aka dtypes , how they map to python and numpy data types and the options for converting from one pandas type to another. A data type is essentially an internal construct that a programming language uses to understand how to store and manipulate data. A possible confusing point about pandas data types is that there is some overlap between pandas, python and numpy. This table summarizes the key points:. For the most part, there is no need to worry about determining if you should try to explicitly force the pandas type to a corresponding to NumPy type. Most of the time, using pandas default int64 and float64 types will work. The only reason I included in this table is that sometimes you may see the numpy types pop up on-line or in your own analysis.

Data comes in many forms, from integers and floats, to strings, dates, and timedeltas. These different types of data are known as data types, or in Pandas dtypes , and using the right ones for your Pandas columns can mean more trouble free Python programming.
