Setting Up Python

To start your Python programming journey, you first need to set up Python on your computer. Follow these steps:

  1. Download Python from the official website.
  2. Install Python by running the downloaded installer.
  3. Verify the installation by opening the terminal and typing python --version.

Variables and Data Types

In this section, we will learn about variables and different data types in Python. Let’s explore some sample codes:

# Define variables
name = "Amina"
age = 25
is_student = True


# Print variables
print("Name:", name)
print("Age:", age)
print("Is Student:", is_student)

Control Flow and Loops

Control flow and loops are essential concepts in programming. Here are some code examples to understand them better:

# If-Else statement
x = 10
if x > 5:
    print("x is greater than 5")
else:
    print("x is less than or equal to 5")


# For loop
fruits = ["apple", "banana", "orange"]
for fruit in fruits:
    print(fruit)


# While loop
count = 0
while count < 5:
    print("Count:", count)
    count += 1

Functions and Modules

Functions and modules help in organizing and reusing code. Here is an example of defining a function and importing modules:

# Define a function
def greet(name):
    print("Hello,", name)


# Importing modules
import math
print("Square root of 16:", math.sqrt(16))

File Handling

Python provides powerful methods for file handling. Let’s see how to read from and write to files:

# Read from a file
file = open("data.txt", "r")
content = file.read()
file.close()
print("File Content:", content)


# Write to a file
file = open("output.txt", "w")
file.write("This is some content.")
file.close()
print("File written successfully.")

Object-Oriented Programming (OOP)

Object-oriented programming is a paradigm that helps in modeling real-world concepts. Here’s an example of creating classes in Python:

# Define a class
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age


    def greet(self):
        print("Hello, my name is", self.name)


# Create an instance of the class
person = Person("Amina", 25)
person.greet()

Working with Databases

Python provides various libraries to interact with databases. Let’s see how to connect to a database and execute queries:

# Connect to a database
import sqlite3
conn = sqlite3.connect("database.db")
cursor = conn.cursor()


# Execute a query
cursor.execute("SELECT * FROM users")
rows = cursor.fetchall()
for row in rows:
    print(row)


# Disconnect from the database
conn.close()

Data Manipulation with Pandas

Pandas is a powerful data manipulation library in Python. Here’s an example of how to work with data using Pandas:

import pandas as pd


# Create a DataFrame
data = {'Name': ['Amina', 'John', 'Emma'], 'Age': [25, 30, 28]}
df = pd.DataFrame(data)


# Print the DataFrame
print(df)


# Filter the DataFrame
filtered_df = df[df['Age'] > 25]
print(filtered_df)

Web Scraping with BeautifulSoup

Web scraping is the process of extracting data from websites. Let’s see how to scrape data using BeautifulSoup:

import requests
from bs4 import BeautifulSoup


# Request webpage
url = "https://www.example.com"
response = requests.get(url)


# Parse HTML content
soup = BeautifulSoup(response.content, "html.parser")


# Extract data
title = soup.title.text
print("Title:", title)
