Used Where?
map()
function is used to apply a function to each of their elements.
When you have an iterable data (a list, tuple, string, dictionary etc.),filter()
function,map()
function can be used together and they both become more useful. This gives map more control on which values to apply the function to.- This combination makes both functions more powerful. However, in Python, list comprehension and dict comprehension can sometimes make map and filter functions obselete.
