    was trying numpy, but no such module

    string = ''.join([''.join(y) for y in (np.array([list(x) for x in matrix]).T.tolist())])

    import re

n, m = map(int, input().split())

matrix = [input() for _ in range(n)]
decoded = ''.join(sum(zip(*matrix), ()))

pattern = r'(?<=\w)([^\w]+)(?=\w)'
print(re.sub(pattern, ' ', decoded))

    Disappointed to see no answer using findall directly (I know why). Here is my solution with findall

    pat = r'^[!@#$%&\s]*[0-9A-Za-z]*[!@#$%&\s]*$|^[!@#$%&\s]*[0-9A-Za-z]+|[0-9A-Za-z]+[!@#$%&\s]*$|[0-9A-Za-z]+'
decoded_script = re.findall(pat, script)
print(' '.join(decoded_script))

    print(re.sub("(?<=\w)(\W+)(?=\w)"," ","".join([matrix[j][i] for i in range(m) for j in range(n)])))
