string conversion

Hi..today i learnt how to convert string to code.instead for getting input from user everytime and placing into a variable...follow this... (e.x) a to z or 1 to 26 variables..

>>> vars = {}
>>> for x in xrange(26):
...  vars[x] = ''
...
>>> for x in xrange(26):
...  vars[x] = raw_input("What is %s? " % x)
...
>>> print vars

{0: ‘a’, 1: ‘b’, 2: ‘c’, 3: ‘d’, 4: ‘e’, 5: ‘f’, 6: ‘g’, 7: ‘h’, 8: ‘i’, 9: ‘j’, 10: ‘k’, 11: ‘l’, 12: ‘m’, 13: ‘n’, 14: ‘o’, 15: ‘p’, 16: ‘q’, 17: ‘r’, 18: ‘s’, 19: ‘t’, 20: ‘u’, 21: ‘v’, 22: ‘w’, 23: ‘x’, 24: ‘y’, 25: ‘z’}
