Lambda function Simple Examples in Python
Despite the fact that I am Data Analyst for 1 year I am still learning simple things. Today I spent some time to test some simple examples dedicated to Lambda function.
I hope that this video will be useful for Data Analysts and for all Python beginners.
Some basic features of Lambda function in practical using are below:
Python has support for so-called anonymous or lambda functions, which are a way of writing functions consisting of a single statement, the result of which is the return value. They are defined with the lambda keyword, which has no meaning other than “an anonymous function”.
There are many cases where data transformation functions will take functions as arguments. It’s often less typing (and clearer) to pass a lambda function as opposed to writing a full-out function declaration or even assigning the lambda function to a local variable.
One reason lambda functions are called anonymous functions is that , unlike functions declared with the def keyword, the function object itself is never given an explicit _name_ attribute.
This video demonstrates some simple examples of Lambda function with short and simple explanations.
