The pass statement in Python is a null operation; it does nothing when executed. It’s often used as a placeholder in code where a statement is syntactically required but you don’t want to write any code yet. This can be useful in loops, functions, classes, or conditional statements where you plan to add code later.

Example Usage

1. In a Function Definition:

def my_function():
    pass  # Placeholder for future code

2. In a Class Definition:

class MyClass:
    pass  # Placeholder for future class attributes and methods

3. In a Loop:

for i in range(10):
    if i % 2 == 0:
        pass  # Placeholder for future code
    else:
        print(i)

4. In Conditional Statements:

x = 10
if x > 0:
    pass  # Placeholder for future code
else:
    print("x is not positive")

The pass statement ensures that the code runs without errors even if the block is empty.
