![]() ![]() In the code above, after renaming the columns in the DataFrame, we access the columns attribute of the DataFrame and print its contents to display the new column names. To display the new column names after renaming them in Pandas, you can simply use the columns attribute of your DataFrame. How do I display the new column names after renaming them in Pandas? This will help you avoid any issues related to spaces in column names and make your column names compatible with various data storage and analysis systems. ![]() The resulting modified DataFrame is then written to a new CSV file using the to_csv() method. In the code above, the str.replace() method is used to replace all spaces in column names with underscores. # Replace spaces with underscores in column namesĭf.columns = df.(' ', '_') To replace spaces with underscores in column names using Pandas, you can use the str.replace() method on the columns attribute of your DataFrame. How do I replace spaces with underscores in column names using Pandas? This will output the same DataFrame with the column names changed in place. Here are a few examples:ĭf = pd.DataFrame(, inplace=True) Alternatively, you can use the columns parameter to pass a list of new column names in the desired order. rename() accepts a dictionary, where the keys are the old column names and the values are the new column names. To rename columns in pandas, you can use the rename() method on a pandas DataFrame. When we want to rename a few specific columns, this approach comes in handy because we need to supply data for the columns that need to be changed.Table of Content To rename columns in pandas Ways to Renaming Columns in Python Using rename() FunctionĪpplying the rename() method is one technique to rename the columns of a Dataframe. Unlike a two-dimensional Python array, a Dataframe of pandas has marked axes. However, Dataframe rows can still have heterogeneous or homogeneous record datatypes throughout any specific row. ![]() Every Pandas Dataframe column holds homogenous records throughout a particular column. It has both rows and columns.Įach column contains an array of data for a particular characteristic or attribute, and each row indicates an observation of a singular event. A dataFrame makes it easy to visualize and work with data. Records are kept in a Pandas DataFrame, a rectangular matrix. ![]() In this tutorial, we'll go through six different methods for changing the column names in a pandas DataFrame. Let's see how to modify a Pandas DataFrame's column titles. Next → ← prev How to Rename Column Names in Python?
