How to rename multiple column headers in a Pandas DataFrame?
In this article, we are going to rename multiple column headers using rename() method. The rename method used to rename a single column as well as rename multiple columns at a time. And pass columns that contain the new values and inplace = true as an argument. We pass inplace = true because we just modify the working data frame if we pass inplace = false then it returns a new data frame.
- Import pandas.
- Create a data frame with multiple columns.
- Create a dictionary and set key = old name, value= new name of columns header.
- Assign the dictionary in columns .
- Call the rename method and pass columns that contain dictionary and inplace=true as an argument.
Below is the implementation:
In this example, we will rename the multiple times using the same approach.
