Code blocks typically refer to sections of code grouped together for a specific purpose and enclosed within curly braces {} in languages like C, C++, and Java. However, Python uses indentation to define blocks of code rather than braces. In Python, indentation is crucial for indicating the structure and scope of the code. An example of how code blocks are represented in Python is:

In the code above, the lines inside the if and else blocks are indented, indicating their association with the respective blocks.
