Replace boolean by string in column of pandas dataframe. In this tutorial, you’ll learn how to use python’s pandas library to convert a column’s values to a string data type. Df2 = df.copy() df2[rating]=pd.to_numeric(df2[rating]) df2.info() pandas.to_datetime() here the column gets converted to the datetime data type.

I Use Pandas 'Ver 0.12.0' With Python 2.7 And Have A Dataframe As Below:

In this article, i will explain how to convert single column or multiple columns to string type in pandas dataframe, here, i will demonstrate using dataframe.astype(str), dataframe.values.astype(str), dataframe.apply(str), dataframe.map(str) and dataframe.applymap(str) methods to covert any type to string type.
