Chapter 1: Getting Started with Python
* Introduces Python and its benefits.
* Explains how to install and run Python.
* Covers basic concepts like variables, data types, and operators.
Example:
```python
# Assign a number to a variable
num = 10
# Print the value of the variable
print(num)
```
Chapter 2: Input and Output
* Demonstrates how to get input from the user and display output.
* Covers string manipulation and formatted output.
Example:
```python
# Get user input as a string
name = input("Enter your name: ")
# Print a formatted string with the input
print(f"Hello, {name}!")
```
Chapter 3: Control Flow
* Introduces conditional statements (if-elif-else) and loops (for, while).
* Explains how to control the flow of execution in a program.
Example:
```python
# Check if a number is even
number = int(input("Enter a number: "))
if number % 2 == 0:
print("The number is even.")
else:
print("The number is odd.")
```
Chapter 4: Functions
* Defines and explains the concept of functions.
* Covers how to define, call, and use functions.
Example:
```python
# Define a function to calculate the area of a circle
def circle_area(radius):
return math.pi * radius2
# Call the function with a radius and print the result
print(circle_area(5))
```
Chapter 5: Data Structures: Lists and Dictionaries
* Introduces lists and dictionaries as data structures.
* Explains how to create, access, and manipulate data within them.
Example:
```python
# Create a list of numbers
numbers = [1, 2, 3, 4, 5]
# Create a dictionary of names and ages
names = {"John": 25, "Jane": 30}
```
Chapter 6: File Handling
* Demonstrates how to read and write to files.
* Explains different modes of file handling and error handling.
Example:
```python
# Open a file for writing
with open("output.txt", "w") as f:
f.write("Hello, world!")
# Open the file for reading and display its contents
with open("output.txt", "r") as f:
print(f.read())
```
Chapter 7: Object-Oriented Programming
* Introduces the concepts of object-oriented programming (OOP).
* Explains classes, objects, inheritance, and polymorphism.
Example:
```python
# Define a class representing a Person
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
# Create an object of the Person class
person = Person("John", 25)
```
Chapter 8: Exception Handling
* Explains how to handle errors and exceptions in Python.
* Covers different types of exceptions and how to catch and process them.
Example:
```python
try:
# Some code that may raise an exception
except Exception as e:
# Handle the exception and provide feedback to the user
print(f"Error: {e}")
```
Chapter 9: Advanced Python Features
* Discusses advanced concepts like generators, iterators, and context managers.
* Explores Python's built-in modules and packages.
Example:
```python
# Use a generator to iterate over a range of numbers
numbers = (x for x in range(10))
```
