Python provides several tools and features that support functional programming, including: Functions: Functions are first-class objects in Python, which means that they can be assigned to variables, passed as arguments to other functions, and returned from functions. Higher-order functions: Higher-order functions are functions that take other functions as arguments or return functions as results. Lambda functions: Lambda functions are anonymous functions that can be defined on the fly. Iterators: Iterators are objects that provide a sequence of values. Generators: Generators are...

Higher-order functions: Higher-order functions are functions that take other functions as arguments or return functions as results. Lambda functions: Lambda functions are anonymous functions that can be defined on the fly. Iterators: Iterators are objects that provide a sequence of values. Generators: Generators are functions that can be used to create iterators. These tools and features can be used to implement a variety of functional programming techniques, such as: Mapping: Mapping is a technique for applying a function to each element in a sequence. Filtering: Filtering is a technique for removing elements from a sequence that do not meet a certain criterion. Reducing: Reducing is a technique for combining the elements of a sequence into a single value. The map() function takes two arguments: a function and a sequence. It applies the function to each element in the sequence and returns a new sequence containing the results. The filter() function takes two arguments: a function and a sequence. It returns a new sequence containing the elements of the original sequence for which the function returns True. The reduce() function takes three arguments: a function, a sequence, and an initial value. It applies the function to each element in the sequence, starting with the initial value, and returns the final result.
