a regex question

[Maggie Q Roth]

Hello

There are two primary types of lines in the log:

60.191.38.xx/
42.120.161.xx   /archives/1005

I know how to write regex to match each line, but don't get the good result
with one regex to match both lines.

Can you help?

Thanks,
Maggie

What is a good result?

The is an re.MULTILINE flag. Did you try that? What does that do?

Could you provide the regexes that you have for each line?

Where did you download it from?
How are you trying it to install?
What error message do you get?

What OS do you run on you PC?

Thank you.

I am just a lurker here, but python is only up to version 3.8. If that is 
python 8, I would wipe it off the system and go get the real thing from 
a genuine python site.  If you paid for it (its free), take whatever 
actions you have to, to get your money back.

Cheers, Gene Heskett

He probably meant 3.8.0 but there was a python 8 (as an april 1 joke by
victor stinner)

When you decode the header you get a number of parts, each with its own 
encoding.


Here's a simple example, based in your code:

from email.header import decode_header

def test(header, default_encoding='utf-8'):
 parts = []

 for data, encoding in decode_header(header):
 if isinstance(data, str):
parts.append(data)
 else:
parts.append(data.decode(encoding or default_encoding))

 print(''.join(parts))

test('=?iso-8859-9?b?T/B1eg==?= ')
test('=?utf-8?Q?=EB=AF=B8?= ')
test('=?GBK?B?0Pu66A==?= ')
test('=?UTF-8?B?zp3Or866zr/PgiDOks6tz4HOs86/z4I=?=

One motivation to base dict key management on equality
(rather than identity) are literals:

Consider a dict "d" with at some place
`d["my example key"] = 1` and at a different place
(maybe another function, another module) you access
`d["my example key"]`. You would expect to get `1`
as result as for your eyes the two literals are equal.
Would the key management be based on identity, then
you could get either the expected `1` or a `KeyError`.
The reason: Python does not manage (most) literals globally;
this means, if you use the same literal in different places
you may (or may not) have non-identical objects.

Basing on equality, you are also more flexibal than
with identity, because can can change the equality
rules for a class while you cannot change the identity rules.
Thus, if you need identity based key management,
define your `__eq__` accordingly.

When I look at these lines, I see 2 fields separated by whitespace
(note that two example lines are very very few to guess the
proper pattern). I would not use a regular expression
in this case, but the `split` string method.

A regular expression for this pattern could be `(\S+)\s+(.*)` which reads
a non-empty sequences of none whitespace (assigned to group 1),
whitespace, any sequence (assigned to group 2)
(note that the regular expression above is given on the
regex level. The string in your Python code may look slightly different).
