How to generate all the values of an iterable besides the last few?
Tag : python , By : GunnarHafdal

may help you . Say I have to define a function which takes in an iterable and generates all of the values except the last 5. As of right now, I have something like this: , I assume saving just 5 items in memory is fine. You can try this:
def generate_all_but_5(iterable):
    x = iter(iterable)
    list_of_current = []
    for i, item in enumerate(x):
        list_of_current.append(item)
        if i >= 5:
            yield list_of_current.pop(0)
list(generate_all_but_5(range(6)))
# [0]
list(generate_all_but_5(range(10)))
# [0, 1, 2, 3, 4]
list(generate_all_but_5('Hello world!'))
# ['H', 'e', 'l', 'l', 'o', ' ', 'w']
def generate_all_but_5(iterable):
    x = iter(iterable)
    list_of_current = []
    for i, item in enumerate(x):
        print(list_of_current) # print the list
        list_of_current.append(item)
        if i >= 5:
            yield list_of_current.pop(0)

g = generate_all_but_5(range(8))
n = next(g)
# []
# [0]
# [0, 1]
# [0, 1, 2]
# [0, 1, 2, 3]
# [0, 1, 2, 3, 4]
# n = 0
n = next(g)
# [1, 2, 3, 4, 5]
# n = 1
n = next(g)
# [2, 3, 4, 5, 6]
# n = 2
n = next(g)
# StopIteration Error

Replace values in iterable with values of another iterable to the same value


Tag : python , By : Sonal

I think the issue was by ths following , You can create a translation table that maps all upper case letters to 'L', all lower case letters to 'l' and all digits to 'n'. Once you have such a map, you can pass it to str.translate().
from string import ascii_uppercase, ascii_lowercase, digits, maketrans
s = "Testing123"

intab = ascii_uppercase + ascii_lowercase + digits
outtab = ('L' * 26) + ('l' * 26) + ('n' * 10)
trantab = maketrans(intab, outtab)

print s.translate(trantab)

Creating an Iterable with values from a different Iterator / Iterable

wish helps you I've written a ADT Sorted BinaryTree with the function: , Just with the standard library, you can do
StreamSupport.stream(entries().spliterator(), false).map(entry -> entry.value).iterator()
IteratorUtils.transformedIterator(bST.getInorderIterator(), entry -> entry.value)

collections.Iterable vs typing.Iterable in type annotation and checking for Iterable


Tag : python , By : Diego

it should still fix some issue The typing.Iterable is generic, so you can say what it's an iterable of in your type annotations, e.g. Iterable[int] for an iterable of ints.
The collections iterable is an abstract base class. These can include extra mixin methods to make the interface easier to implement when you create your own subclasses.

Iterable.generate: Iterable<Future<String>> throws Exception


Tag : dart , By : dlouzan

should help you out The map method returns a new lazy Iterable with elements that are created by calling the function argument on each element of the Iterable in iteration order. You instead return the original iterable.
Also You have to return an iterable, not an iterator, so do not apply the iterator getter.
Iterable<Future<String>> getFutureIterataleData(int sec) {
  var iterable = new Iterable.generate(5);

  return iterable.map(
    (n) =>  Future<String>((){return "Hello";}));

  }
