What is the difference between map, lambda, filter, reduce? How should we use all these in python?
Sometimes I get confused on what function to use based on a scenario and how to use it.

Swetha Lakshme S ,
Have you tried to use searchbar?
See this what I found after using searchbar....

Quick quide...
You can use map, lambda, filter, and reduce to manipulate data in Python.
For example..
MAP-you can use map to apply a function to each element in a list..
FILTER-You can use filter to remove elements from a list based on a condition..
REDUCE-You can use reduce to find the sum or product of all elements in a list.
For Scenario...
The choice of which function to use depends on the specific scenario.
#Map and filter are useful when you want to transform or filter elements in a sequence.
#Reduce is useful when you want to compute a single result from a sequence.
#Lambda is useful when you want to define a small, anonymous function on the fly
