A question which has perhaps no answer. This command do exactly what I expect
M=[input(r'ABCD : '),input('BCDA: '),input('BCAD: ')]
but I have potentially a huge list to input and as the inputs are asked sequentially this will take ahuge number of rows in in my screen.
So is there a mechanism which permit to select multi-columns in each rows ?
One solution would be to use a single input for a number of entries.
The user would enter inputs separated by spaces.
Then you would split the resulting string according to spaces.
Something like:
sage: s = 'ABCD BCDA BCAD DACB: '
sage: M = input(s).split()
ABCD BCDA BCAD DACB: 7 8 0 3
sage: M
['7', '8', '0', '3']
Slelievre as you certainly have already seen I have found a way to input datas minimizing the error from the user. Your solution could be fine if there was a way to be sure that if I ask for 4 number the user did not enter 5 which is there possible. I will come back soon perhaps with a good solution.
