Lambda functions in Python are small, anonymous functions defined with the 'lambda' keyword. They are useful for creating simple functions without needing to formally define a function using 'def'. This tutorial will guide you through various examples of using lambda functions, focusing on practical...
How to use the lambda function with filter()? Thefilter()function in Python takes in a function and an iterable (lists,tuples, andstrings) as arguments. The function is called with all the items in the list, and a new list is returned, which contains items for which the function evalua...
