Pandas: Select a row of series/dataframe by given integer index
Write a Pandas program to select a row of series/dataframe by given integer index.
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
Index-2: Details
col1 col2 col3
2 3 6 9
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(data=d)
print("Original DataFrame")
print(df)
result = df.iloc[[2]]
print("Index-2: Details")
print(result)
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 Index-2: Details col1 col2 col3 2 3 6 9
Explanation:
The above code first creates a Pandas DataFrame df with columns col1, col2, and col3 using a dictionary 'd'.
result = df.iloc[[2]] – This code selects the third row of the DataFrame using the iloc() method with index location [2] and stores it in a new DataFrame called result.
Finally print() function prints the DataFrame containing only the third row of 'df'.
