How to get the row of a given Python array index

In the example, I reported the position of the line as fixed, and then I reported the starting position of the column to the end position:

lista1 = [1, 6, 4, 4, 5]

lista2 = [2, 2, 3, 4, 6]

lista3 = [3, 9, 8, 7, 3]

lista4 = [4, 7, 3, 8, 0]

matriz = [lista1] + [lista2] + [lista3] + [lista4]

colunas = matriz[2][1:5]

print(colunas)  

So you can only get the values of the columns that you want, just go by changing the positions of the rows and columns to get different values.

I hope I have helped you.

I have another question, taking advantage of what is in the same file.

When the user is going to choose a number, for example column 2, internally python will work in column 3, I made a test with the code that I modified, causing the user to ask for the column.

  

list1 = [1, 2, 3, 4, 5]

     

list2 = [2, 2, 3, 4, 6]

     

list3 = [3, 9, 8, 7, 3]

     

list4 = [4, 7, 3, 8, 0]

     

array = [list1] + [list2] + [list3] + [list4]

     

number = int (input ("enter the number:"))

     

column = [line [number] for line in array]

     

columns = array [number] [0: 5]

     

columns [1] = 9

     

print (columns)

I tested the solution I had already found.

  

list1 = [1, 2, 3, 4, 5]

     

list2 = [2, 2, 3, 4, 6]

     

list3 = [3, 9, 8, 7, 3]

     

list4 = [4, 7, 3, 8, 0]

     

array = [list1] + [list2] + [list3] + [list4]

     

column = [line [0] -1 for line in array] # -1 type 2 and edit number 2 of column 1

     

print (column [3])

But this way of inserting -1 in the for did not work in the main code. What's missing to work like this second code?
