Preco sa deje toto:

>>> import re

>>> rexp = '.+\.\d\d[odm]'

>>> file2send = 'mop2032j.08d.Z'

>>> re.match(rexp,file2send)

<<_sre.SRE_Match object at 0x00A81640>

Preco tam nie je False, alebo aspon None? Inokedy mi to normalne fungovalo.
Nechapem tiez toto:

>>>rexp = '\s*-.*\..*'

>>>num = 3.14159

>>>print re.match(rexp,str(num))

None



>>>rexp = '\s*-*.*\..*'

>>>num = 3.14159

>>>print re.match(rexp,str(num))

<_sre.SRE_Match object at 0x00A81640>

Co sa deje? Preco to nefunguje ako ma? Co mam robit ak chcem vyhodnocovat tito reg.vyrazy?

Re: regular expressions

co mash robit , mozes zacat citat API ;)

match(string[, pos[, endpos]])
If zero or more characters at the beginning of string match this regular expression, return a corresponding MatchObject instance. Return None if the string does not match the pattern; note that this is different from a zero-length match.

v tom prvom riadnu halusku pises ;) ono to trosku inak funguje pozri priklady:
