The pass statement is used as a placeholder for future code. When the pass statement is executed, nothing happens, but you avoid getting an error when empty code is not allowed. Empty code is not allowed in loops, function definitions, class definitions, or in if statements.
read lessIn Python, pass
is a null statement. It does nothing and it is often used as a placeholder or a stub in situations where a statement is required syntactically, but no action is needed or desired.
The pass
statement is often used in situations such as:
pass
statement as a placeholder until you have the actual implementation.Example:
def my_function():
pass # Placeholder for function implementation
pass
statement.Example:
while True:
pass # Empty loop
except
block. In this case, you can use the pass
statement to indicate that no action is needed.Example:
try:
some_function()
except ValueError:
pass # Do nothing if a ValueError is raised
Also,
When defining an abstract class in Python, you can use the pass
statement to indicate that a method is abstract, i.e., it has no implementation in the abstract class itself. The concrete subclasses of the abstract class are then responsible for providing an implementation for the abstract methods.
Here's an example of using pass
in an abstract class definition:
from abc import ABC, abstractmethod
class Shape(ABC):
@abstractmethod
def area(self):
pass
@abstractmethod
def perimeter(self):
pass
In the above example, the Shape
class is an abstract class that defines two abstract methods, area()
and perimeter()
. The pass
statement is used in the method definitions to indicate that the methods are abstract and have no implementation in the abstract class itself. Any concrete subclass of Shape
must provide an implementation for these methods.
So in this context, the pass
statement is used to provide a placeholder for abstract methods that are meant to be implemented by concrete subclasses.
