Python Coding challenge - Day 356| What is the output of the following Python Code?

 

Step 1: Importing the Pandas Library

import pandas as pd  

This line imports the pandas library, which is used for data manipulation and analysis in Python.

Step 2: Creating a Dictionary

data = {"A": [1, 2, 3]}  

A dictionary named data is created with a single key "A" and a list of values [1, 2, 3].

Step 3: Creating a DataFrame

df = pd.DataFrame(data)  

This converts the dictionary data into a pandas DataFrame.

The resulting DataFrame looks like this:

   A

0  1

1  2

2  3

Step 4: Filtering the DataFrame

df[df["A"] > 1]

Here, df["A"] > 1 creates a Boolean condition:

0    False

1     True

2     True

Name: A, dtype: bool

This condition is applied to df, keeping only the rows where column "A" has values greater than 1.

The resulting DataFrame is:

   A

1  2

2  3

Step 5: Printing the Filtered DataFrame

print(df[df["A"] > 1])

This prints the filtered output:

   A

1  2

2  3

Final Answer:

A: Rows with A > 1
