Pandas: Rename all columns with the same pattern of a given DataFrame

Last update on December 21 2024 07:42:21 (UTC/GMT +8 hours)

Write a Pandas program to rename all columns with the same pattern of a given DataFrame.

Sample Solution :

Python Code :

import pandas as pd
df = pd.DataFrame({
    'Name': ['Alberto Franco','Gino Mcneill','Ryan Parkes', 'Eesha Hinton', 'Syed Wharton'],
    'Date_Of_Birth ': ['17/05/2002','16/02/1999','25/09/1998','11/05/2002','15/09/1997'],
    'Age': [18.5, 21.2, 22.5, 22, 23]
})

print("Original DataFrame")
print(df)
df.columns = df.columns.str.lower().str.rstrip()
print("\nRemove trailing (at the end) whitesapce and convert to lowercase of the columns name")
print(df.head())

Sample Output:

Original DataFrame
             Name Date_Of_Birth    Age
0  Alberto Franco     17/05/2002  18.5
1    Gino Mcneill     16/02/1999  21.2
2     Ryan Parkes     25/09/1998  22.5
3    Eesha Hinton     11/05/2002  22.0
4    Syed Wharton     15/09/1997  23.0

Remove trailing (at the end) whitesapce and convert to lowercase of the columns name
             name date_of_birth   age
0  Alberto Franco    17/05/2002  18.5
1    Gino Mcneill    16/02/1999  21.2
2     Ryan Parkes    25/09/1998  22.5
3    Eesha Hinton    11/05/2002  22.0
4    Syed Wharton    15/09/1997  23.0
