Python Coding challenge - Day 340| What is the output of the following Python Code?

 

Code Explanation:

import pandas as pd

import pandas as pd: This line imports the Pandas library, which is a powerful Python library used for data manipulation and analysis. By convention, it is imported with the alias pd.

df = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})

df = pd.DataFrame(...): This line creates a DataFrame named df using Pandas' DataFrame() constructor. The DataFrame is a 2-dimensional labeled data structure, similar to a table or spreadsheet.

{'A': [1, 2], 'B': [3, 4]}: This is a dictionary where:

'A': [1, 2] creates a column labeled 'A' with values [1, 2].

'B': [3, 4] creates a column labeled 'B' with values [3, 4].

The resulting DataFrame will look like this:

   A  B

0  1  3

1  2  4

print(df.iloc[0, 1])

df.iloc[0, 1]: This line uses integer-location based indexing to select a value from the DataFrame.

df.iloc[] is used to select rows and columns based on their integer positions (not labels).

0: Refers to the first row (index 0).

1: Refers to the second column (index 1), which is labeled 'B'.

So, df.iloc[0, 1] selects the value at the intersection of the first row and the second column, which is 3 (from df[0, 'B']).

Finally, it prints 3.

Final Output: 3
