Execution Sample

Data Analysis Python

import pandas as pd

data = {'Name': ['Anna', 'Ben'], 'Age': [28, 34]}
df = pd.DataFrame(data)
df.head()

This code creates a small table with names and ages, then shows the first rows.

Execution Table

Step	Action	Code Line	Result/Output
1	Import pandas library	import pandas as pd	pandas module loaded
2	Create data dictionary	data = {'Name': ['Anna', 'Ben'], 'Age': [28, 34]}	{'Name': ['Anna', 'Ben'], 'Age': [28, 34]}
3	Create DataFrame from data	df = pd.DataFrame(data)	DataFrame with 2 rows and 2 columns created
4	Display first rows	df.head()	Name Age 0 Anna 28 1 Ben 34

💡 Code execution ends after displaying the DataFrame head.

Variable Tracker

Variable	Start	After Step 2	After Step 3	After Step 4
data	undefined	{'Name': ['Anna', 'Ben'], 'Age': [28, 34]}	{'Name': ['Anna', 'Ben'], 'Age': [28, 34]}	{'Name': ['Anna', 'Ben'], 'Age': [28, 34]}
df	undefined	undefined	DataFrame with 2 rows and 2 columns	Same DataFrame displayed

Key Moments - 2 Insights

Why do we not see any output after importing pandas?

Importing a library loads it but does not produce visible output, as shown in step 1 of the execution_table.

What does df.head() show and why?

df.head() shows the first few rows of the DataFrame to give a quick look at the data, as seen in step 4.

Visual Quiz - 3 Questions

Look at the execution_table at step 3, what is the value of variable df?

A A dictionary with names and ages

B A DataFrame with 2 rows and 2 columns

C Undefined

D A list of names

💡 Hint

Check the 'Result/Output' column at step 3 in execution_table.

At which step does the code display the data table output?

A Step 4

B Step 1

C Step 3

D Step 2

💡 Hint

Look for the step where df.head() is called in execution_table.

If we remove the line 'import pandas as pd', what will happen at step 3?

A DataFrame will be created successfully

B Data dictionary will be printed

C Error because pandas is not defined

D Nothing will happen

💡 Hint

Without importing pandas, pd.DataFrame cannot be used as shown in variable_tracker.

Full Transcript

Google Colab is an online tool where you can write and run Python code without installing software. You open your browser, go to colab.research.google.com, and create a new notebook. Then you write Python code, like importing pandas and creating a table. When you run the code, it executes on Google's servers and shows the output below the code. This way, you can do data analysis easily and save your work to Google Drive.
