pytest segfault, not with -v
by Marco Sulla Dec. 19, 2021

Dec. 19, 2021

I have a battery of tests done with pytest. My tests break with a segfault if I run them normally. If I run them using pytest -v, the segfault does not happen. What could cause this quantical phenomenon?

Update a specific element in all a list of N lists
by hanan lamaazi Dec. 19, 2021

Dec. 19, 2021

Dear All, I really need your assistance, I have a dataset with 1005000 rows and 25 columns, The main column that I repeatedly use are Time, ID, and Reputation First I sliced the data based on the time, and I append the sliced data in a list called "df_list". So I get 201 lists with 25 columns The main code is starting for here: for elem in df_list: {do something.....} {Here I'm trying to calculate the outliers} Out.append(outliers) Now my problem is that I need to locate those outliers in the df_list and then update another column with is the "Reputation" Note that the there is a duplicated IDs but at different time slot example is ID = 1 is outliers, I need to select all ID = 1 in the list and update their reputation column I tried those solutions: 1) grp = data11.groupby(['ID']) for i in GlobalNotOutliers.ID: data11.loc[grp.get_group(i).index, 'Reput'] += 1 for j in GlobalOutliers.ID: data11.loc[grp.get_group(j).index, 'Reput'] -= 1 It works for a dataframe but not for a list 2) for elem in df_list: elem.loc[elem['ID'].isin(Outlier['ID'])] It doesn't select the right IDs, it gives the whole values in elem 3) Here I set the index using IDs: for i in Outlier.index: for elem in df_list: print(elem.Reput) if i in elem.index: # elem.loc[elem[i] , 'Reput'] += 1 m = elem.iloc[i, :] print(m) It gives this error: IndexError: single positional indexer is out-of-bounds I'm greatly thankful to anyone who can help me,

Dear All, We are happy to announce a new edition of the Dogelog Player: - Binary Release: The new version 0.9.7 of the Dogelog player now masters DCG. We have decided to upload the transpiled and compacted editions for the JavaScript and Python platforms to www.xlog.ch under the heading "Products". - Quelltexte: As an alternative to GitHub, we have now activated pages.xlog.ch. In addition to the source texts of the transpiler and the built-ins of the Dogelog player, this website also contains the manuals and the source texts of the tutorials. Both JavaScript and Python source code can be found. - Blogging: As an alternative to Gist, we are now reporting on medium.com/@janburse_2989 about the developments in the Dogelog player. We also use twitter.com/dogelogch and www.facebook.com/groups/dogelog for short messages.

A problem with itertools.groupby
by ast Dec. 17, 2021

Dec. 17, 2021

Python 3.9.9 Hello I have some troubles with groupby from itertools from itertools import groupby for k, grp in groupby("aahfffddssssnnb"): print(k, list(grp)) print(k, list(grp)) a ['a', 'a'] a [] h ['h'] h [] f ['f', 'f', 'f'] f [] d ['d', 'd'] d [] s ['s', 's', 's', 's'] s [] n ['n', 'n'] n [] b ['b'] b [] It works as expected. itertools._grouper objects are probably iterators so they provide their datas only once. OK but: li = [grp for k, grp in groupby("aahfffddssssnnb")] list(li[0]) [] list(li[1]) [] It seems empty ... I don't understand why, this is the first read of an iterator, it should provide its data. This one works: ["".join(grp) for k, grp in groupby("aahfffddssssnnb")] ['aa', 'h', 'fff', 'dd', 'ssss', 'nn', 'b'] regards

ast.parse, ast.dump, but with comment preservation?
by samue...＠gmail.com Dec. 16, 2021

Dec. 16, 2021

I wrote a little open-source tool to expose internal constructs in OpenAPI. Along the way, I added related functionality to: - Generate/update a function prototype to/from a class - JSON schema - Automatically add type annotations to all function arguments, class attributes, declarations, and assignments alongside a bunch of other features. All implemented using just the builtin modules (plus astor on Python < 3.9; and optionally black). Now I'm almost at the point where I can run it—without issue—against, e.g., the entire TensorFlow codebase. Unfortunately this is causing huge `diff`s because the comments aren't preserved (and there are some whitespace issues… but I should be able to resolve the latter). Is the only viable solution available to rewrite around redbaron | libcst? - I don't need to parse the comments just dump them out unedited whence they're found… Thanks for any suggestions PS: Library is https://github.com/SamuelMarks/cdd-python (might relicense with CC0… anyway too early for others to use; wait for the 0.1.0 release ;])

Getting the exit code of a subprocess
by Jason Dec. 16, 2021

Dec. 16, 2021

Hello, How can I find out the exit code of a process when using the subprocess module? I am passing an email message to a shell script and I need to know whether the shell script threw an error. Here is my code: p = Popen(cmd, stdout=None, stdin=PIPE, stderr=None) p.communicate(input=msg) I tried something like this: e_stat = p.communicate(input=msg) but the value of e_stat is always '(None, None)' -- Thanks & best regards, Jason Rissler
