Getting Started with Python
Let’s explore the basics of Python programming. Open your favorite code editor and follow along.
Variables and Data Types
In Python, you can assign values to variables. Here’s an example:
Python supports various data types such as integers, floats, strings, lists, tuples, and dictionaries. Here’s how you can define variables of different data types:
Control Flow
Python provides several control flow statements to make decisions and repeat code blocks. Let’s look at a few examples:
If-else statement
For loop
While loop
Functions
Functions in Python allow you to encapsulate a block of code and reuse it whenever necessary. Here’s an example:
Libraries and Modules
Python has a vast ecosystem of libraries and modules that extend its functionality. To use a library, you first need to install it. For example, let’s install and use the numpy
library, which provides support for numerical operations.
To install numpy
, run the following command in your command prompt or terminal:
Once installed, you can import and use numpy
in your Python code:
