Introduction

In today’s digital economy, organizations generate huge amounts of data every single day. However, raw data alone is not useful unless businesses can analyze it and turn it into meaningful insights.

One of the most powerful tools used in data analytics today is Python. Python has become one of the most popular programming languages in the world because it is simple, powerful, flexible, and beginner-friendly.

Unlike some programming languages that are difficult for beginners to understand, Python uses readable syntax that looks almost like normal English.

What Is Python?

Python is a high-level programming language created by Guido van Rossum and released in 1991. It was designed to be simple, readable, and easy to learn.

A high-level language means programmers can write code using human-friendly commands instead of complicated machine instructions.

For example, displaying a message in Python only requires one line of code:

print("Hello world")
Enter fullscreen mode Exit fullscreen mode

This simplicity is one of the main reasons Python is popular among beginners.

Python is also versatile. It can be used in many industries and fields such as: Data analytics, Data science, Artificial intelligence, Machine learning, Web development, Cybersecurity
and Software development

Why Python Is Popular in Data Analytics

Python has become one of the most widely used tools in the data analytics space for several reasons.

1. Python Is Easy to Learn

Python syntax is clean and readable.

For example:

age = 21

if age >= 18:
    print("Adult")
else:
    print("Minor")
Enter fullscreen mode Exit fullscreen mode

Even beginners can understand what this code is doing.

2. Python Has Powerful Data Libraries

Python has many built-in libraries and external packages that make data analysis easier.

Instead of writing long and complicated code, analysts can use specialized libraries to complete tasks quickly.

Popular libraries include: Pandas, NumPy, Matplotlib, Seaborn and Scikit-learn
These libraries help analysts to:

  • Clean data
  • Analyze data
  • Create charts
  • Perform calculations
  • Build predictive models

3. Python Has a Large Community

Millions of people use Python worldwide. This means beginners can easily find: Tutorials, Documentation, YouTube videos, Coding forums and Online courses -If a beginner encounters an error, there is a high chance someone else has already solved the same problem online.

4. Python Handles Large Amounts of Data

Businesses often work with thousands or millions of rows of data.
Python can process large datasets efficiently and integrate with:

  • SQL databases
  • APIs
  • Excel files
  • Cloud platforms
  • Machine learning tools This makes Python valuable in modern organizations.

Python Libraries Used in Data Analytics

Python libraries are collections of pre-written code that help developers complete tasks faster.

1. Pandas

Pandas is one of the most important Python libraries for data analytics. It is mainly used for:

  • Reading data
  • Cleaning data
  • Filtering records
  • Grouping information
  • Performing calculations
  • Working with tables

Example: Loading a Logistics Dataset

Below is an example of loading the logistics dataset using Pandas.

import pandas as pd
url =
"https://raw.githubusercontent.com/NelimaL/LOGISTICS_DATA/refs/heads/main/LOGISTICS_MOCK_DATA%20(1).json"
df = pd.read_json(url)
Enter fullscreen mode Exit fullscreen mode

Display first 5 rows by slicing 

print(logistics_df[:5])
Enter fullscreen mode Exit fullscreen mode

This code imports the logistics dataset and displays the first five rows.

2. NumPy

NumPy is used for numerical operations and mathematical calculations.

Example: Calculating Average Delivery Time 

import numpy as np

delivery_times = [2, 3, 24, 13, 4]

average_time = np.mean(delivery_times)

print("Average Delivery Time:", average_time)
Enter fullscreen mode Exit fullscreen mode

Output 

Average Delivery Time: 9.2
Enter fullscreen mode Exit fullscreen mode

3. Matplotlib

Matplotlib is used for creating charts and graphs.

Example: Visualizing Delivery Ratings 

import matplotlib.pyplot as plt
ratings = [2, 5, 2, 3, 4]
plt.hist(ratings)
plt.title("Delivery Ratings")
plt.xlabel("Ratings")
plt.ylabel("Frequency")
plt.show()
Enter fullscreen mode Exit fullscreen mode

This creates a histogram showing how delivery ratings are distributed.

4. Seaborn

Seaborn is another visualization library that creates more attractive statistical charts.

Example: Delivery Time vs Package Weight 

import seaborn as sns
import matplotlib.pyplot as plt
sns.scatterplot(
    x=logistics_df["package_weight"],
    y=logistics_df["delivery_time"]
)
plt.title("Package Weight vs Delivery Time")
plt.show()
Enter fullscreen mode Exit fullscreen mode

This chart helps analysts determine whether heavier packages take longer to deliver.

How Python Is Used to Clean Data

Real-world datasets are rarely perfect.
Data often contains:

  • Missing values
  • Duplicate records
  • Incorrect formats
  • Typing errors
  • Invalid values Data cleaning is one of the most important steps in analytics.

Checking for Missing Values 

# Check missing values
print(logistics_df.isnull().sum())
Enter fullscreen mode Exit fullscreen mode

This code checks how many missing values exist in each column.

Removing Duplicate Records 

# Remove duplicates
logistics_df = logistics_df.drop_duplicates()
print("Duplicates removed")
Enter fullscreen mode Exit fullscreen mode

Duplicate records can affect business reports and calculations.

Converting Date Columns

Dates are very important in analytics.

# Convert dates
logistics_df["delivery_date"] = pd.to_datetime(logistics_df["delivery_date"])
logistics_df["pickup_date"] = pd.to_datetime(logistics_df["pickup_date"])
Enter fullscreen mode Exit fullscreen mode

This converts the columns into proper date format.

Checking Data Types 

print(logistics_df.dtypes)
Enter fullscreen mode Exit fullscreen mode

Understanding data types helps analysts know which operations can be performed.

How Python Is Used to Analyze Data

Once data is cleaned, analysts can start extracting insights.

Example 1: Counting Delivery Statuses

A logistics company may want to know how many deliveries were:

  • Delivered
  • Returned
  • In Transit
  • Out for Delivery 
status_count = logistics_df["delivery_status"].value_counts()
print(status_count)
Enter fullscreen mode Exit fullscreen mode

Example Output 

Delivered           6
Returned            5
In Transit          4
Out for Delivery    5
Enter fullscreen mode Exit fullscreen mode

This helps management monitor operational performance.

Example 2: Average Delivery Rating 

average_rating = logistics_df["delivery_rating"].mean()

print("Average Delivery Rating:", average_rating)
Enter fullscreen mode Exit fullscreen mode

Example Output 

Average Delivery Rating: 3.4
Enter fullscreen mode Exit fullscreen mode

This helps companies evaluate customer satisfaction.

Example 3: Finding the Fastest Deliveries 

fastest_delivery = logistics_df.sort_values(
    by="delivery_time"
)

print(fastest_delivery[["tracking_number", "delivery_time"]].head())
Enter fullscreen mode Exit fullscreen mode

This identifies packages delivered in the shortest time.

Example 4: Analyzing Delivery Companies 

company_count = logistics_df["delivery_company"].value_counts()

print(company_count)
Enter fullscreen mode Exit fullscreen mode

This shows how many deliveries each company handled.

Example 5: Average Package Weight 

average_weight = logistics_df["package_weight"].mean()

print("Average Package Weight:", average_weight)
Enter fullscreen mode Exit fullscreen mode

This helps logistics companies understand shipment trends.

How Python Is Used to Visualize Data

Data visualization helps analysts communicate findings clearly.

Instead of reading large tables, decision-makers can quickly understand charts and graphs.

Example 1: Bar Chart of Delivery Status 

status_count = logistics_df["delivery_status"].value_counts()
status_count.plot(kind="bar")
plt.title("Delivery Status Distribution")
plt.xlabel("Delivery Status")
plt.ylabel("Count")
plt.show()
Enter fullscreen mode Exit fullscreen mode

This chart shows the number of packages in each delivery status.

Example 2: Pie Chart of Delivery Ratings 

rating_count = logistics_df["delivery_rating"].value_counts()
rating_count.plot(kind="pie", autopct="%1.1f%%")
plt.title("Delivery Ratings")
plt.ylabel("")
plt.show()
Enter fullscreen mode Exit fullscreen mode

This chart helps visualize customer satisfaction levels.

Example 3: Line Graph of Delivery Time 

logistics_df["delivery_time"].plot(kind="line")
plt.title("Delivery Time Trend")
plt.xlabel("Shipment Number")
plt.ylabel("Delivery Time")

plt.show()
Enter fullscreen mode Exit fullscreen mode

This graph helps analysts identify delivery trends.
