What's returns map() and filter()?

Question

I tried to print result of using map or filter function but got error!

Answer 1

Theophile, output for "print(map(int, ["2", "3", "10"]))" is "<map object at 0x682e28c>"

Answer 2

They return map or filter objects. If you want to get the list, you have to do something like :
list(map(int, liste)) #returns a list

Answer 3

Filter is a function that filter an array of a condition made by the programmer, map is to apply a function in the entire array.

Could you show the code to see where is the error?

Answer 4

Why i can't print filter or map object?
I want see exactly result of using map or filter function, not the list, that i will get if use list(map or filter)

Answer 5

print(map(int, ["2", "3", "10"]))

Answer 6

Lothar, thanks

Answer 7

you can also iterate over map and filter objects..

for i in map(int, ["2", "3", "10"]):
print(i)

you can also also nest the functions in case you’re dealing with nested iterables😀
