Non Empty Lines

You need to count how many non-empty lines a given text has.
An empty line is a line without symbols or the one that contains only spaces.
Input: A text (str).
Output: An integer (int).
Examples:
assert non_empty_lines("one simple line\n") == 1 assert non_empty_lines("") == 0 assert non_empty_lines("\nonly one line\n ") == 1 assert ( non_empty_lines( "\nLorem ipsum dolor sit amet,\n\nconsectetur adipiscing elit\nNam odio nisi, aliquam\n " ) == 3 )
