#a list of integers
nums = [1, 2, 3]

#a list of letters
ltrs = ['a', 'b', 'c']

#a list to hold the result
rslt = []

for i in nums:
    for j in ltrs:
        rslt.append(str(i) + j)
        #for bonus points uncomment the following line
        #rslt.append(j + str(i))

print(rslt)


'''RESULT
['1a', '1b', '1c', 
 '2a', '2b', '2c', 
 '3a', '3b', '3c']

   BONUS RESULT
['1a', 'a1', '1b', 'b1', '1c', 'c1', 
 '2a', 'a2', '2b', 'b2', '2c', 'c2', 
 '3a', 'a3', '3b', 'b3', '3c', 'c3']
