I have seen this type of problem on many Python test sites and books. I created this code in both C# and Python sections to show the difference in coding.
def print_alpha_numeric(abc_list, number_list):
for char in abc_list:
for num in number_list:
print(char, num)
return
print_alpha_numeric(['a', 'b', 'c'], [1, 2, 3])
