How to limit the the numbers generated?

[pratikchhapolika]

k=list(sre_yield.AllStrings('[a-zA-Z]\d{7}')) Is there way to limit the numbers as to generate 9 digit it would take lot of time.

Yes -- how would you like them to be limited? Are you willing to modify the original regex?

Do you want something repeatable, or just statistical?

The top two ways I'd recommend are:

>>> import sre_yield
>>> import sre_constants
>>> sre_yield.CATEGORIES[sre_constants.CATEGORY_DIGIT] = "01"
>>> len(sre_yield.AllStrings('[a-zA-Z]\d{7}'))
6656
>>> sre_yield.AllStrings('[a-zA-Z]\d{7}')[-10:]
['Q1111111', 'R1111111', 'S1111111', 'T1111111', 'U1111111', 'V1111111', 'W1111111', 'X1111111', 'Y1111111', 'Z1111111']

Or

>>> import sre_yield
>>> import random
>>> [random.choice(sre_yield.AllStrings('[a-zA-Z]\d{7}')) for _ in range(10)]
['G6070677', 'y0605526', 'j9597732', 'S7015557', 'b9563158', 'M9610555', 'V6049622', 'r7271609', 'B5294687', 'w1351517']
