Rename columns in a Python Pandas DataFrame
The Problem
How do I rename the columns in a Python Pandas DataFrame?
The Solution
You can use the DataFrame.rename() method to rename columns. Assign the result back to the same variable to apply the change:
my_dataframe = my_dataframe.rename(columns={'old_column': 'new_column', 'old_column2': 'new_column2'})Any columns not renamed will retain their existing names.
