elif list comprehension code example

Example 1: python list comprehension elif

>>> l = [1, 2, 3, 4, 5]
>>> ['yes' if v == 1 else 'no' if v == 2 else 'idle' for v in l]
['yes', 'no', 'idle', 'idle', 'idle']

Example 2: python if else list comprehension

# Basic syntax for if:
desired_elements = [f(x) for x in iterable_object if condition]

# Basic syntax for if else:
desired_elements = [f(x) if condition else g(x) for x in iterable_object]

# Basic syntax for if elif else:
desired_elements = [f(x) if condition elif condition_2 g(x) else h(x) for x in iterable_object]

# Example usage:
# Say you want to return the square of elements if elements are less 
# than 10, otherwise you just want to return the elements themselves:
your_list = [1, 7, 13, 11, 23, 2, 17, 42, 8, 5]
new_list = [x**2 if x < 10 else x for x in your_list]
print(new_list)
--> [1, 49, 13, 11, 23, 4, 17, 42, 64, 25]

Example 3: elixir list comprehension

iex> for n <- [1, 2, 3, 4], do: n * n
[1, 4, 9, 16]

..   "blue"
.. ]

> for color <- colors, do: IO.puts(color)

> red
> yellow
