Generate in flight string from [A-z]

Question

I want to know what is a simplest way to write method which generates me number from 1 to 50, and then depends of generated number returns me string like:

Abcdef if generated number is 6
Abcdefghi if generated number is 9.

I'm using python 3.2

Answer 1

There's a few approaches, the simplest:

>>> import string
>>> import random
>>> string.ascii_letters[:random.randint(1, 50)].title()
'Abcdefghijklmnopq'
>>> string.ascii_letters[:random.randint(1, 50)].title()
'Abcdefghijklmnopqrstuvwxyzabcdefghijklmnopq'
>>> string.ascii_letters[:random.randint(1, 50)].title()
'Abcdefghijklmnopqrs'    

Or you can have a go with itertools:

>>> import string
>>> import random
>>> from itertools import islice, cycle
>>> def randstr():
...     return ''.join(islice(cycle(string.ascii_lowercase),
...                           random.randint(1, 50))).title()
...
>>> randstr()
'Abcdefghijklmnopq'
>>> randstr()
'Abcdefghijklmnopqrstuvwxyzabcdefghijklmnopq'
>>> randstr()
'Abcdefghijklmnopqrs'
