Python map

TIL

There is a built-in Python function called map.

Python official documentation has it listed...

map(function, iterable, *iterables)

Return an iterator that applies function to every item of iterable, yielding the results.

But doesn't have any example code (maybe a good opportunity to contribute?)

Examples

>>> a, b = map(int, ["123", "007"])
>>> a
123
>>> b
7

>>> a, b = map(len, ["apple", "banana"])
>>> a
5
>>> b
6

>>> def add(n):
...     return n + n

>>> result = map(add, [1, 2, 3, 4])
>>> list(result)
[2, 4, 6, 8]

line = "1-2,3-4"

# How I did
a, b, c, d = [int(x) for x in line.replace(",", " ").replace("-", " ").split()]

# How it could've been done
a, b, c, d = map(int, line.replace(",", "-").split("-"))
