This program is easy to understand:

>>> i = 1
>>> print "i\ti**2\ti**3\ti**5\ti**10\ti**20"
i i**2 i**3 i**5 i**10 i**20
>>> while i <= 10:
...     print i, '\t', i**2, '\t', i**3, '\t', i**5, '\t', i**10, '\t', i**20
...     i += 1
...
1 1 1 1 1 1

6 36 216 7776 60466176 3656158440062976
7 49 343 16807 282475249 79792266297612001

9 81 729 59049 3486784401 12157665459056928801
10 100 1000 100000 10000000000 100000000000000000000

Well from the program it tells the out put to be put into a table('\t'). From this then it puts the equation into the correct line. 

>>> i = 1

>>> print "%-4s%-5s%-^s%-*s%-13s%-15s" % \

...     ('i', 'i**2', 'i**3', 'i**5', 'i**10', 'i**20')

>>> while i <= 10:

...     print "%-4d%-5d%-6d%-8d%-13d%-15d%" % (i, i**2, i**3, i**5, i**10, i**20)

...     i += 1

... 

i    i**2   i**3   i**5   i**10    i**20

1   1    1     1       1            1              

2   4    8     32      1024         1048576        

3   9    27    243     59049        3486784401     

4   16   64    1024    1048576      1099511627776  

5   25   125   3125    9765625      95367431640625 

6   36   216   7776    60466176     3656158440062976

7   49   343   16807   282475249    79792266297612001

8   64   512   32768   1073741824   1152921504606846976

9   81   729   59049   3486784401   12157665459056928801

10  100  1000  100000  10000000000  100000000000000000000

The change on this program is that it outputted with i, i**2, i**3, i**5, i**10, and i**20

>>> 'Python'[1]

'y'

>>> "Strings are sequences of characters."[5]

'g'

>>> len("wonderful")

9

>>> 'Mystery'[:4]

'Myst'

>>> 'p' in 'Pinapple'

True

>>> 'apple' in 'Pinapple'

True

>>> 'pear' in 'Pinapple'

False

>>> 'apple' > 'pinapple'

False

>>> 'pinapple' < 'Peach'

False
