Pass specifies a Python statement without operations. It is a placeholder in a compound statement. If we want to create an empty class or functions, this pass keyword helps to pass the control without error.
# For Example
class Student:
pass # Passing class
class Student:
def info():
pass # Passing function
In Python, pass is a null operation. It is generally used as a placeholder where syntactically some code is required but no action is needed. It essentially does nothing and acts as a placeholder to avoid syntax errors.
Here’s an example of how pass can be used:
def my_function():
pass # Placeholder for future implementation
# or
if some_condition:
pass # Placeholder for future implementation
else:
# some code here
In these examples, pass serves as a placeholder, allowing the code to be syntactically correct until it is implemented further. It can be particularly useful in situations like defining empty classes, functions, or loops where you plan to implement the body later.
