How to write an empty function in Python - pass statement?
Published on Aug. 22, 2023, 12:15 p.m.
In Python, you can write an empty function using the pass
statement. The pass
statement is a null operation in Python, which means it performs no action. Here’s an example of how to write an empty function:
def my_function():
pass
In this example, we define a function called my_function()
with no arguments or implementation. The pass
statement is used to create an empty code block, which satisfies the requirement that a function must have at least one statement.
The pass
statement can also be used in other situations where an empty or placeholder block of code is required, such as in loops or conditionals. It is useful when writing incomplete code that can be filled in later, or for defining functions or classes that do not have any implementation yet.
Note that using pass
to write empty code blocks should be used judiciously, as it can make code harder to read and maintain if overused. It is important to make sure that pass
statements are properly commented to explain their purpose and avoid confusion.
