    the first option(better):

    print(re.sub(r'\b\W+\b', ' ', ''.join([''.join([x[i] for x in matrix]) for i in range(m)])))

    the second option:

    s = ''.join([''.join([mat[i] for mat in matrix]) for i in range(m)])
t = max([''] + re.findall(r'[0-9a-zA-Z].*[0-9a-zA-Z]', s))
tn = re.sub(' +', ' ', re.sub(r'[!@#$%&]', ' ', t))
print(s.replace(t, tn))

    Solution I made

    import math
import os
import random
import re
import sys


first_multiple_input = input().rstrip().split()

n = int(first_multiple_input[0])

m = int(first_multiple_input[1])

matrix = ["" for i in range(m)]

for _ in range(n):
    matrix_item = input()
    for j in range(len(matrix_item)):
        matrix[j] = matrix[j]+str(matrix_item[j])

encoded = "".join(matrix)
print(re.sub(r'(?<=\w)[^\w]+(?=\w)', ' ', encoded))

    Neo could have gotten a cleaner line. But Neo decided to remove characters only between words...
