58. Select All Except One Column

Write a Pandas program to select all columns, except one given column in a DataFrame.

Sample Solution :

Python Code :

import pandas as pd
d = {'col1': [1, 2, 3, 4, 7], 'col2': [4, 5, 6, 9, 5], 'col3': [7, 8, 12, 1, 11]}
df = pd.DataFrame(data=d)
print("Original DataFrame")
print(df)
print("\nAll columns except 'col3':")
df = df.loc[:, df.columns != 'col3']
print(df)

Sample Output:

Original DataFrame
   col1  col2  col3
0     1     4     7
1     2     5     8
2     3     6    12
3     4     9     1
4     7     5    11

All columns except 'col3':
   col1  col2
0     1     4
1     2     5
2     3     6
3     4     9
4     7     5
