Can't seem to understand map function in Python.

Question

Would like a basic explanation

Answer 1

Simply this function takes two types of parameters. The first one is a function and the second is iterable(like lists, tuples...). the map function will applies the function(the parameter) to each element in the iterable and return alist of results.

example :
def addX(x):
return x+x

list1 = [1,2,3,4]

list2 = map(addX,list1)
#it will take the first element in the list and returns it as a parameter for addX(). and repeat that for rhe rest of the element.

print(list2)

Output:
[2,4,6,8]

Answer 2

Such a clear and great explanation! Thanks alot!
