Answer 1

With one list:

with open('my_file.txt', 'w') as f:
    f.write('n'.join(str(x) for x in my_list))

WIth two lists:

with open('my_file.txt', 'w') as f:
    to_write = ""
    for i, (a, b) in enumerate(zip(list1, list2)):
        to_write += f'{a},{b}n' if i < len(list1) - 1 else  f'{a},{b}'
    f.write(to_write)

fname = "myfile.txt"
num_list = [1, 2, 3, 4]

# open the file
with open(fname,"w") as fw:
   # Iterate through the elements, minus the last one
   for num in num_list[:-1]:
      # Write the number as a string, the concatenate a new line
      fw.write(str(num)+"n")
   fw.write(str(num_list[-1]))
