Fundamentals of Python Programming Language
=====================================================
Introduction
Python is a high-level, interpreted programming language that is widely used in various fields such as web development, scientific computing, data analysis, artificial intelligence, and more. Its simplicity, flexibility, and large community make it an ideal choice for beginners and experienced programmers alike.
Brief History of Python
Python was first released in 1991 by Guido van Rossum, a Dutch computer programmer. Initially, it was designed as a scripting language to replace the ABC programming language. Over time, Python has evolved into a mature, feature-rich language that is widely used today.
Basic Syntax and Data Types
Indentation
Python uses indentation (spaces or tabs) to denote block-level structure. This means that you need to use consistent indentation to define code blocks within loops, conditional statements, and functions.
Variables and Assignment
Variables in Python are declared without a specific data type. You can assign a value to a variable using the assignment operator (=).
| Data Type | Description |
|---|---|
| Integers | Whole numbers (e.g., 1, 2, 3) |
| Floats | Decimal numbers (e.g., 3.14, -0.5) |
| Strings | Sequences of characters (e.g., “hello”, ‘hello’) |
Basic Operators
Python supports various operators for arithmetic, comparison, logical, and assignment operations.
| Operator | Description |
|---|---|
+ | Addition |
- | Subtraction |
* | Multiplication |
/ | Division |
== | Equal to |
!= | Not equal to |
< | Less than |
> | Greater than |
Control Structures
Python supports various control structures such as conditional statements (if-else), loops (for, while), and functions.
Conditional Statements
x = 5
if x > 10:
print("x is greater than 10")
elif x == 5:
print("x is equal to 5")
else:
print("x is less than 10")
Loops
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(fruit)
i = 0
while i < len(fruits):
print(fruits[i])
i += 1
Functions and Modules
Defining Functions
Functions in Python are defined using the def keyword.
def greet(name):
print("Hello, " + name + "!")
greet("John")
Importing Modules
Python has a vast collection of modules that provide various functionalities. You can import these modules using the import statement.
| Module | Description |
|---|---|
math | Mathematical functions (e.g., sin, cos, sqrt) |
random | Random number generation |
