Re: Form validation number and text only no space mac 4 numbers

Oh, I thought you needed only 4 total chars. 

Using a regex probably is a bit overkill here:

>>> import string

>>> accepted = string.letters + string.digits

>>> max_numbers = 4

>>> 

>>> def test(word):

...     numbers = 0

...     for c in word:

...         if c.isdigit():

...             numbers += 1

...         if not c in accepted or numbers > max_numbers:

...             return False

...     return True

... 

>>> 

>>> test('gerd12')

True

>>> test('gerd1234')

True

>>> test('gerd 1234 ')

False

>>> test('gerd 1234')

False

>>> test('%$$%%#$')

False

>>> test('gerd123456')

False

to explain myself a bit more:

gerd12 = should be valid

gerd1234   = should be valid

gerd 1234 = should not be valid

%$$%%#$ = should not be valid

gerd123456 - should not be valid

etc etc
