I'm still learning with this technology. May I know how to put all values in one column using python and xlsx writer?

Ex.

my_dict = {
'Bob': ['eating', 'watching', 'drinking'], 
'Ann': ['shopping', 'eating', 'drawing'], 
'May': ['riding', 'singing', 'dancing']
}

What I did was putting it in another column temporarily.

col_num = 0
row_num = 7
for key, value in my_dict.items():
    worksheet.write(row_num, col_num, key)
    worksheet.write_column(row_num + 1, col_num, value)
    col_num += 1

May I know how can I achieve this kind of format? Hoping to get your opinions and suggestions. Thank you
