Easy Single Inheritance Fundamentals
Solve in Playground →

Problem Statement

Create a `Parent` class and a `Child` class inheriting from it. Instantiate `Child` as `c`. Use `isinstance()` to print whether `c` is an instance of `Child`, `Parent`, and `str` on separate lines.

Input Format

None

Output Format

Print True or False for each check on a new line.

Constraints

None

Sample Output

True
True
False

Explanation

An object of a derived class is considered an instance of both its own class and its base class.

Starter Code

class Parent:
    pass
class Child(Parent):
    pass

if __name__ == '__main__':
    c = Child()
    # Use isinstance() and print the results
    pass

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
