2. Introduction to Python
Python is a high-level, interpreted programming language known for its readability.
It was created by Guido van Rossum and released in 1991.
Python is widely used in web development, data analysis, artificial intelligence, and
automation.
3. Installing Python
You can download Python from the official
website python.org.
The installation process varies slightly
depending on your operating system.
After installation, you can verify it by opening a
command prompt and typing `python --version`.
4. Basic Python Syntax
Python uses indentation to define code blocks,
such as loops and functions.
Comments are written with the `#` symbol and
are used for explaining code.
Python code is case-sensitive, meaning variables
like `MyVar` and `myvar` are different.
5. Variables and Data Types
Variables in Python are created when you assign a value to them, without declaring their type.
Common data types include integers, floats, strings, booleans, and lists.
Python is dynamically typed, so variables can change their data type during execution.
6. Control Structures
`if`, `elif`, and `else` statements are used to
make decisions in code.
Loops like `for` and `while` enable repetitive
execution of code blocks.
Proper indentation is essential for control
structures to function correctly.
7. Functions in Python
Functions are blocks of reusable code defined
using the `def` keyword.
They can accept parameters and return values
to make code more modular.
Python also includes many built-in functions
like `print()`, `len()`, and `range()`.
8. Working with Data Collections
Lists are ordered, mutable collections for
storing multiple items.
Tuples are similar to lists but are immutable.
Dictionaries store data in key-value pairs and
are useful for quick lookups.
9. Summary and Next Steps
Python's simplicity makes it a great language
for beginners and experts alike.
Practice writing small programs to reinforce
understanding of core concepts.
Explore additional topics like file handling,
modules, and object-oriented programming to
expand your skills.
