Answer 4

In [44]: l1 = ['a', 'bb', 'c']

In [45]: [' %s '%x for x in l1]
Out[45]: [' a ', ' bb ', ' c ']

Answer 5

As always, use a list comprehension:

lst = [' {0} '.format(elem) for elem in lst]

This applies a string formatting operation to each element, adding the spaces. If you use python 2.7 or later, you can even omit the 0 in the replacement field (the curly braces).

Answer 6

Indent your python code first! And then:

lst = ['a', 'b', 'c']
lst2 = [' ' + a + ' ' for a in lst]
print lst2
