What is the Lambda function?
In Python, a lambda function is an anonymous function that can have any number of arguments but only one expression. It is defined using the lambda keyword instead of the standard def keyword, making it suitable for situations where a small function is needed for a short period.
Why use a Lambda function?
Lambda functions in Python are useful for creating small, one-time, anonymous function objects. They are often used for short functions where defining a named function would be unnecessary, enabling more concise code and promoting a functional programming style.
How does a Lambda function work?
A Lambda function, also known as an anonymous function, works by allowing you to create small, one-line functions without a name. It can take any number of arguments but can only have one expression. It is typically used when you need a simple function for a short period of time.
Tutorial Python – Using Lambda Functions
Create a Lambda function with 1 argument.
This creates a lambda function that takes the MYVAR argument and returns it converted to uppercase.
Here is the script output.
Create a Lambda function with 2 arguments.
This creates a lambda function that takes VAR1 and VAR2 arguments and returns their sum.
Here is the script output.
Conclusion
Enhance code efficiency with Lambda functions in Python. Discover how these concise, anonymous functions streamline operations and promote a more elegant programming approach.
