In this post, we will see 3 different methods to Reordering the columns of Pandas Dataframe :

Using reindex method

You can use DataFrame’s reindex() method to reorder columns of pandas DataFrame.

You need to pass columns=[$list_of_columns] to reindex() method to reorder columns of Pandas DataFrame.

Output :

Given Dataframe :
Name Gender Age Course Branch College
0 Ankit M 23 B.tech Cse Geu
1 Aishwarya F 21 B.tech Cse Geu
2 Shaurya M 22 B.sc It Gehu
3 Shivangi F 21 B.sc It Gehu

Dataframe after Re-ordering of columns :
Name Age Gender College Course Branch
0 Ankit 23 M Geu B.tech Cse
1 Aishwarya 21 F Geu B.tech Cse
2 Shaurya 22 M Gehu B.sc It
3 Shivangi 21 F Gehu B.sc It

Using column selection through column name

We can use column selection through column name of DataFrame to reorder the column.

Here is an example:
