How to display matrix input values without [' ']

Question

I made an array with 12 elements that has 4 rows and columns and wanted them to be displayed like this without [' '] in list form, but I don’t want the output to be displayed like this:

Remembering: Should work with negative floats numbers and positive floats typed

Entrada:
02 04 06
08 10 12
14 16 18
20 22 24

Saída esperada:
02 04 06
08 10 12
14 16 18
20 22 24

Mas a saída está assim:
['02', '04', '06']
['08', '10', '12']
['14', '16', '18']
['20', '22', '24']

Meu código:
mt1 = input().split()
mt2 = input().split()
mt3 = input().split()
mt4 = input().split()

print (mt1)
print (mt2)
print (mt3)
print (mt4)

Answer 1

There are several ways to do this, as can be seen in the other answers. I will leave a solution that, in my view, is quite elegant.

You may have noticed that the function print can receive several parameters, resulting in printing each of the parameters separated by a space.

print('sem', 'tempo,', 'irmão') => printa "sem tempo, irmão"

Through the asterisk (which is the operator of unpack), Python allows using the values of a list as arguments of a function.

argumentos = ['sem', 'tempo,', 'irmão']
print(*argumentos) => printa "sem tempo, irmão"

Knowing this, you can use the same technique in your code.

print(*mt1)
print(*mt2)
print(*mt3)
print(*mt4)

The result will be what you want.

If you want to put another separator other than a space, just enter in the named parameter sep.

print(*mt1, sep=' - ')

Answer 2

well, I wouldn’t recommend doing so but I can help.

mt1 = input().split()
mt2 = input().split()
mt3 = input().split()
mt4 = input().split() # a função split retorna uma lista, mesmo que contendo apenas um elemento

matriz = [mt1,mt2, mt3, mt4] # já que você está trabalhando com lista junte tudo numa lista apenas 

for i in range(len(matriz)): # para varrer as linhas da matriz
    for j in range(len(matriz[i])): # para varrer todos os elementos da linha ou seja as colunas.
        print (matriz[i][j], end = "\t") # printa o elemento da linha um ao lado do outro 
    print() # dá espaço para uma nova linha.

remembering that this is not the best solution you could use a chained list, or something like.

Answer 3

You can use the method .join() string. The use is

# STRING.join(LISTA)
# Exemplo:
print( ".".join(['192', '168', '0', '1']))
# result: 192.168.0.1

But in your case, just put it in the print lines:

mt1 = input().split()
mt2 = input().split()
mt3 = input().split()
mt4 = input().split()

print (' '.join(mt1))
print (' '.join(mt2))
print (' '.join(mt3))
print (' '.join(mt4))
