How to print nested list into charter side by side in python

Question

In python

I want to print above nested list into character which are side by side example output:

Consider a nested comprehension along with str.join:

>>> a = [['z', 'G', 'j', 'E', 'U'], ['%', '#', '(', '!', ')'], ['6', '4', '8', '1', '3']]
>>> print(''.join(c for chars in a for c in chars))
zGjEU%#(!)64813

For the golfers `print(''.join(map(''.join, a))` – flakes Dec 11 '22 at 05:04

a = [['z', 'G', 'j', 'E', 'U'], ['%', '#', '(', '!', ')'], ['6', '4', '8', '1', '3']]
result = ""
for item in a:
    for char in item:
        result += char

result:

'zGjEU%#(!)64813'
