There are many ways. Here's a couple:

>>> print(('%sth\n' * len(a)) % tuple(a))
4th
5th
6th
7th

>>> print(('{}th\n' * len(a)).format(*a))
4th
5th
6th
7th

If you particularly like using map then:

>>> print(''.join(map('%sth\n'.__mod__, a)))
4th
5th
6th
7th

>>> print(''.join(map('{}th\n'.format, a)))
4th
5th
6th
7th
