There is no need for you to try to downcast to a smaller I recommend that you allow pandas to convert to specific size This is not a native data type in pandas so I am purposely sticking with the float approach.Īlso of note, is that the function converts the number to a python I also suspect that someone will recommend that we use a The values to integers as well but I’m choosing to use floating point in this case. The code uses python’s string functions to strip out the ‘$” and ‘,’ and thenĬonvert the value to a floating point number. replace ( '$', '' ) return float ( new_val ) Create a custom function to convert the dataĭef convert_currency ( val ): """ Convert the string number value to a float - Remove $ - Remove commas - Convert to float type """ new_val = val.In order to convert data types in pandas, there are three basic options: Until we clean up these data types, it is going to be very difficult to do much Refer to this article for an example the expands on the currency cleanups described below.Īfter looking at the automatically assigned data types, there are several concerns:Ĭolumns are stored as objects, not numerical values such as aĪre also stored as objects not numerical values Some additional techniques to handle mixed data types in For instance, the a column could include integers, floatsĪnd strings which collectively are labeled as an One other item I want to highlight is that theĬontain multiple different types. However, the basic approaches outlined in this article apply to these Types are better served in an article of their own I included in this table is that sometimes you may see the numpy types pop up on-lineįor this article, I will focus on the follow pandas types: To explicitly force the pandas type to a corresponding to NumPy type. Int_, int8, int16, int32, int64, uint8, uint16, uint32, uint64įor the most part, there is no need to worry about determining if you should try Text or mixed numeric and non-numeric values This table summarizes the key points: Pandas Or, if you have two strings such as “cat” and “hat” you could concatenate (add) themĪ possible confusing point about pandas data types is that there is some overlapīetween pandas, python and numpy. Needs to understand that you can add two numbers together like 5 + 10 to get 15. Uses to understand how to store and manipulate data.
