How could I print out the same result but with better, short code?

Question

a = "PAYPALISHIRING"
i = 0
res = ''
while i < len(a):
res += a[i]
res += ' '
i += 4
s = 1
res1 = ''
while s < len(a):
res1 += a[s]
res1 += ' '
s += 2
t = 2
res2 = ''
while t < len(a):
res2 += a[t]
res2 += ' '
t += 4
final = res + res1 + res2
final1 = final.split()
print res
print res1
print res2
final = ''.join(final1)
print final
