36. Drop Rows from DataFrame

Write a Pandas program to drop a list of rows from a specified DataFrame.

Sample data:
Original DataFrame
col1 col2 col3
0 1 4 7
1 4 5 8
2 3 6 9
3 4 7 0
4 5 8 1
New DataFrame after removing 2nd & 4th rows:
col1 col2 col3
0 1 4 7
1 4 5 8
3 4 7 0

Sample Solution :

Python Code :

import pandas as pd
import numpy as np
d = {'col1': [1, 4, 3, 4, 5], 'col2': [4, 5, 6, 7, 8], 'col3': [7, 8, 9, 0, 1]}
df = pd.DataFrame(d)
print("Original DataFrame")
print(df)
print("New DataFrame after removing 2nd & 4th rows:")
df = df.drop(df.index[[2,4]])
print(df)

Sample Output:

Original DataFrame
   col1  col2  col3
0     1     4     7
1     4     5     8
2     3     6     9
3     4     7     0
4     5     8     1
New DataFrame after removing 2nd & 4th rows:
   col1  col2  col3
0     1     4     7
1     4     5     8
3     4     7     0

Explanation:

The above code creates a Pandas DataFrame ‘df’ using a Python dictionary ‘d’. The DataFrame has three columns: 'col1', 'col2', and 'col3'.

df = df.drop(df.index[[2,4]]): This code drops rows with indices 2 and 4 using the drop() method with the index parameter set to a list of indices to drop.

Finally print() function prints the resulting DataFrame with the two rows dropped.
