List the elements of an array in python

You don't exactly have an array, more like a list of lists. The most classic iterative way would be to do something like this:

for lista in array:
  for elemento in lista:
    print(elemento)

We loop through each list within arrayand then each element of these lists.

Another very compact way, which is basically similar to the previous one, is to use "list comprehension"

print("\n".join([elemento for lista in array for elemento in lista]))

In this case, what we achieve is a "flat" list with all the elements, and then we concatenate all of these into a newline-separated string.

You can do for example:

for element in array:
    for subElement in element:
        print(subElement)

or what would be the same:

[print(subElement) for element in array for subElement in element]

you can do it like this:

from functools import reduce
array = [['[email protected]'], ['[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]']]

for x in reduce(lambda x,y: x+y,array):
    print(x)
