You can validate line before import, you can do a specific RE for check a more detailed line and so on, it's more powerful. For simple i mean simple programming code.

string in files
guys i need info on how to call up different words in a line of a file using python example : file = 'this is a python coding group' i want to assign a xter to this, is, a, python , coding and group thanks -- http://mail.python.org/mailman/listinfo/python-list
RE: string in files
Simple solution: us result=yourString.split( ) and you get a list with all the words. -Original Message- From: python-list-bounces+rbqg84=motorola@python.org [mailto:python-list-bounces+rbqg84=motorola@python.org] On Behalf Of ibpe...@gmail.com Sent: Tuesday, December 30, 2008 3:43 PM To: python-list@python.org Subject: string in files guys i need info on how to call up different words in a line of a file using python example : file = 'this is a python coding group' i want to assign a xter to this, is, a, python , coding and group thanks -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list

Re: string in files
thanks brother
i mean how do i particularly assign (u = this)
(y = is)
in the strings up there. i have been able to split strings with any
character sign.
If i'm not wrong this is simple with RE:
In [1]: st = 'this is a python coding group'
In [2]: import re
In [3]: re.compile( (?Pfirst.*) (?Psecond.*) (?Pt.*) (?Pfo.*)
(?Pfi.*) (?Psi.*) )
Out[3]: _sre.SRE_Pattern object at 0x9e93ac0
In [4]: rule = re.compile( (?Pfirst.*) (?Psecond.*) (?Pt.*)
(?Pfo.*) (?Pfi.*) (?Psi.*) )
In [5]: m = rule.match( st )
In [6]: dir(m)
Out[6]:
['__copy__', '__deepcopy__',
'end', 'expand',
'group', 'groupdict',
'groups', 'span', 'start']
In [7]: m.groupdict().items()
Out[7]:
[('si', 'group'),
('second', 'is'),
('t', 'a'),
('fi', 'coding'),
('fo', 'python'),
('first', 'this')]
In [8]: dict(m.groupdict().items())
Out[8]:
{'fi': 'coding',
'first': 'this',
'fo': 'python',
'second': 'is',
'si': 'group',
't': 'a'}

Well, if you *know* you have a particular number of words in the string you can say u, v, w, x, y, z = 'this is a python coding group'.split() But if you have a variable number of words this isn't practical in Python 2, though Python 3 has features that make it easier. The real question is what is the larger goal you are trying to achieve. Where a programmer is trying to create names dynamically there are usually better ways to proceed. Could you tell us a little more about what you are trying to do? regards Steve -- Steve Holden+1 571 484 6266 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ -- http://mail.python.org/mailman/listinfo/python-list
