How do I output lists as a table in Jupyter notebook?

Question

I know that I\'ve seen some example somewhere before but for the life of me I cannot find it when googling around.

I have some rows of data:

data = [[1,2         


        

Answer 1

Ok, so this was a bit harder than I though:

def print_matrix(list_of_list):
    number_width = len(str(max([max(i) for i in list_of_list])))
    cols = max(map(len, list_of_list))
    output = '+'+('-'*(number_width+2)+'+')*cols + '\n'
    for row in list_of_list:
        for column in row:
            output += '|' + ' {:^{width}d} '.format(column, width = number_width)
        output+='|\n+'+('-'*(number_width+2)+'+')*cols + '\n'
    return output

This should work for variable number of rows, columns and number of digits (for numbers)

data = [[1,2,30],
        [4,23125,6],
        [7,8,999],
        ]
print print_matrix(data)
