In pandas, you can change the data type of a column using the astype() function. You can pass a dictionary to the astype() function where the keys are the column names and the values are the new data types. For example, if you have a DataFrame called df and you want to change the...
You can change the column name of Pandas DataFrame by using the DataFrame.rename() method and the DataFrame.columns() method. In this article, I will explain how to change the given column name of Pandas DataFrame with examples. Advertisements Use the pandas DataFrame.rename() function to modi...
Pandas In a Pandas DataFrame, we can check the data types of columns with the dtypes method. df.dtypesName stringCity stringAge stringdtype:object The astype function changes the data type of columns. Consider we have a column with numerical values but its data type is string. This is a ...
iloc[:, i] = X_validation.iloc[:, i].astype(str) to col_name = X.columns[i] X[col_name] = X[col_name].astype(str) if X_validation is not None: X_validation[col_name] = X_validation[col_name].astype(str) this prevents Future warning from pandas of setting incompatible dtype...
