Python Full Course For Beginners Lesson No 1.0

 

Lesson 1: Introduction to Python

Understanding Python

In this lesson, we'll introduce Python and explore its key features, applications, and basic syntax. Python is a high-level, interpreted programming language known for its simplicity and readability.

Key Features of Python

1. Readability:

 Python's clean and concise syntax makes it easy to read and write code, enhancing developer productivity.

2. Interpreted: 

Python is an interpreted language, meaning code is executed line by line without the need for compilation, allowing for rapid development and testing.

3. Dynamic Typing:

 Python uses dynamic typing, allowing variables to be assigned without specifying their data types explicitly, making code more flexible.

4. High-level Data Structures:

 Python comes with built-in data structures such as lists, dictionaries, and sets, simplifying data manipulation and processing.

5. Rich Standard Library: 

Python's extensive standard library provides modules and functions for various tasks, reducing the need for external dependencies.

Setting Up Python Environment

To start programming in Python, you'll need to set up your development environment. You can install Python and a code editor of your choice such as VSCode, PyCharm, or Jupyter Notebook.

Writing Your First Python Program

Let's write a simple "Hello, World!" program in Python to get started:

```python
print("Hello, World!")
```

 

 

Explanation

- The `print()` function is used to display output to the console.
- `"Hello, World!"` is the message that will be printed.

Running Python Programs

After writing your Python program, you can run it using the Python interpreter.

Example: Running Hello World Program

Assuming your Python file is named `hello.py`:

```
$ python hello.py
```
