Hi-
I have several different dictionaries. I want to make a unique list of
all the keys in all the dictionaries. What would be the best way of doing
that?
Thanks.

Hi folks,
I am a newbie to Python and am hoping that someone can get me started
on a log parser that I am trying to write.
The log is an ASCII file that contains a process identifier (PID),
username, date, and time field like this:

2348 williamstim 02AUG03 14:11:20

I want to enforce such a constraint on a column that would ensure that the
values be all unique, but this wouldn't apply to NULL values. (I.e. there
may be more than one NULL value in the column.)
How can I achieve this?
I suppose I would get the most-hated "table/view is changing,
trigger/function may not see it" error if I tried to write a trigger that
checks the uniqueness of non-null values upon insert/update.

I'm still learning python so this might be a crazy question but I
thought I would ask anyway. Can anyone tell me if it is possible to
join two dictionaries together to create a new dictionary using the
keys from the old dictionaries?
The keys in the new dictionary would be the keys from the old
dictionary one (dict1) and the values in the new dictionary would be
the keys from the old dictionary two (dict2). The keys would be joined

I have a new system Im building that stores entries of what people are
searching for on my sites.
I want to be able to keep records of how many times a keyword was
searched for daily, and from that I can calculate weekly and monthly.
At this point I have one entry per search phrase with the number of
hits the search phrase has gotten, and the last time it was updated.
As I start to take the program out of testing and move in more...

Is there a typical way to create a dictionary (or hash table) with two
values, instead of one?
Currently, my data structure is TWO dictionaries, each with matching
and fully sychronized keys. This allows me to have one key with two
values (one value in each dictionary). This is ugly code as the
dictionaries could get out of synch (due to a bug or something).

Hello All,
I'm attempting to create multiple dictionaries at once, each with unique
variable names. The number of dictionaries i need to create depends on the
length of a list, which was returned from a previous function.
The pseudo code for this problem would be:
returnedlist =
count = 0
for i in returnedlist:
if count < len(returnedlist):

A dictionary with keys is perfectly reasonable. But a *list* of values has to be searched linearly for every value: a O(n) process. As your friend suggested, searching a dictionary requires O(1) time. A set is even better in this case, because you don't have any use for the values in the inner dictionary (sets and dictionaries are very similar in the...

Hi,
Wouldn't it be nicer to have 'in' return values (or keys) for both
arrays and dictionaries. Arrays and Dictionaries looked so similar in
Python until I learned this difference.
Thanks,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
