Upendra Kumar added the comment: @Terry, The attached files contain the master branch of the pip_gui. It contains all the work done by me till now in pip_gui. If this projects need to be continued as open source project, is it expected to be continued as independent project, or CPython project or pip project. I am confused about it. However, I think that the project should be continued with pip, which will also help speed up the process of standardization of output of pip for different commands. I believe still there are a lot of pip commands not having 'json' output. -- Added file: http://bugs.python.org/file46500/pip_gui-master.zip ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27051> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Tkinter based GUI for PIP : Needed Feedback
Hello everyone, We have made a preliminary version of GUI for PIP. This project is a part of GSoC 2016. This project is intended to provide a GUI version for "pip". ( target audience for the project : beginners in Python ). The project idea is discussed on these issues : 1. Issue #23551 : IDLE to provide menu link to PIP gui. 2. Issue #27051 : Create PIP GUI The GitHub repo of the project : https://github.com/upendra-k14/pip_gui Therefore, we would like to have feedback on this project so that we can improve the GUI and other features to it. Please post as many issues and suggestions here : https://github.com/upendra-k14/pip_gui/issues. -- https://mail.python.org/mailman/listinfo/python-list

Upendra Kumar added the comment: For using threading with Tkinter there are two options : either to use threading or asyncio ( coroutines ). Because asyncio is easier as compared to threading, therefore I would like to use it. But, coroutines are available only in Python >=3.5.

I am trying something similar to BrownTruck in issue :

I tried to execute pip.main('install','-U',) from a thread.

There is some problem with threading.local() in pip.utils.logging. Can anyone
please suggest a workaround for it. It is necessary for me to use threads other
than the main GUI thread to update text. I need to update text and do long
processes ( like searching for results using pip search command or installing
or uninstalling) when someone presses a button.
When I don't use threading to update text, the GUI text is updated only after
the callback returns.

Upendra Kumar added the comment: In ref. to msg269264: @Terry, I am ready to maintain this project. But for as backup is concerned I really don't know a lot of people and where should I look for them. In reference to msg269038: I was more engrossed in reading through other messages related to pip gui that I forgot to clarify about it. For pip install and uninstall command, I have used the pip.main() instead of subprocess module. There were two reasons for it ( what I thought): 1. More reliable, because I thought the output on CLI may change more frequently than arguments in pip.main(). (I think may be this assumption is wrong). 2. I figured out a way to clear pip loggers ( which caused to produce duplicate output ). I found it on a issue in pip Github repo : Adding one line of : pip.logger.consumers = [] in runpip(). It cleared the pip loggers responsible for producing duplicate output. ( due to this I liked pip.main(). The only troubling part about it was duplicate output ) This is just what I thought. I can very easily switch to subprocess module. Very less changes will be required in the code. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27051> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Upendra Kumar added the comment: @Terry, code updates can be followed on https://github.com/upendra-k14/pip_gui/tree/dump_code Please review the code in dump_code branch. For now, only pip_gui_v3.py is relevant. 1. I had doubt about including a private module from pip ( "pip._vendor" ). As this module contains a lot of important utilites I have included it by copying the "_vendor" module in my package and changed all the package references of "pip._vendor" to "pip_tkinter._vendor" to make it work. Since, it was a private module, I included it by copying it. One more reason is that pip has mentioned this module has immutable. There are very less chances that further changes in this module will be introduced in future. 2. Except a few complex commands like install, I have planned to inherit the pip command classes. For example, I have inherited the pip.commands.SearchCommand class from pip and overrided the "run" method. It helped me to give finer control over the search results. For example, Now we can retrieve all previous versions of a package ( which is not provided by pip ) and search results can be directly obtained in form of tuple lists without parsing the output. But, I think doing something similar for pip.commands.InstallCommand is very difficult. Therefore, for now I have chosen to use "runpip and pip.main" for pip install command. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27051> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Upendra Kumar added the comment: Here, I have one doubt regarding the get_data function that should the get_data function be a common function for different features for example : def _get_data(self, func_option): """ A separate function for extracting data from the runpip() function. It is done in order to get this function tested using unittest module According to func_option, it returns the data extracted : Options: --- 1. list : for listing all currently installed packages 2. show : show details of installed packages 3. search : show formated search results 4. install : get results while installing packages """ splitted_options = func_option.split() if splitted_options[0] == 'list': return runpip(func_option) elif splitted_options[0] == 'show': return runpip(func_option) elif splitted_options[0] == 'search': return runpip(func_option) elif splitted_options[0] == 'install': return runpip(func_option) I am not clear would this single function for retrieving data would be good for uniitest or different functions would be good for retrieving data. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23551> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23551] IDLE to provide menu link to PIP gui.
Upendra Kumar added the comment: I am trying to make a Tk based GUI for pip package manager. In reference to msg256736, I am confused about the discovery method mentioned. Is there any way already implemented to detect the Python versions installed systemwide? Moreover, how to manage the non-standard installation of Python by users? I think in that case, it would be very difficult to detect the Python versions installed in the user's system. In addition to it different tools used for installation of Python generally end up in installing in different folders or paths. Therefore, initially what functionality should I try to implement in it?

[issue26001] Tutorial: write() does not expect string in binary mode
Upendra Kumar added the comment: I also think that for better clarification, binary mode and text mode should be specified clearly for both methods read() and write(). For read(), I have changed it to: ' some quantity of data and returns it as a string (in text mode) or bytes object (in binary mode).' For write(), I have changed it to: ' To write something other than a string (in text mode) or bytes object (in binary mode), it needs to be converted first to string or bytes object respectively.

[issue26002] make statistics.median_grouped more efficient
New submission from Upendra Kumar: statistics.median_grouped currently uses cf=data.index(x) to find the leftmost position of x in data ( line number 445 ). Here, data.index() has linear time complexity, which may not be good for long lists. But, here since the list 'data' is sorted beforehand, we can use binary search ( bisect_left() ) to find the leftmost occurrence of 'x' in 'data'. Similarly, for counting number of occurrence of 'x' in data after sorting, we can find the position of rightmost occurrence of 'x' in data[l1len(data)], where l1 is position of leftmost occurrence of 'x' (line number 447 ) -- components: Library (Lib) files: median_grouped.patch keywords: patch messages: 257419 nosy: upendra-k14 priority: normal severity: normal status: open title: make statistics.median_grouped more efficient type: performance versions: Python 3.4, Python 3.5, Python 3.6 Added file: http://bugs.python.org/file41484/median_grouped.patch ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26002> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue21592] Make statistics.median run in linear time
Upendra Kumar added the comment: This is my first attempt to contribute. I have used the Median of Medians with n/5 groups of 5 elements each. It has linear time complexity. But, still I am not sure about it, because constants may be high. Therefore, if anyone can please benchmark it with other methods or check that can this method be a viable solution to finding median more efficiently?

how to compare two fields in python
I have a very basic question in python. I want to go through each line of the a csv file and compare to see if the first field of line 1 is same as first field of next line and so on. If it finds a match then i would like to put that field in an object1 else put that field in a different object2. Finally i would like to count how many of the fields in object1 vs object2. Can this be done in python? Here is a small example. BRM_1 679 1929 BRM_1 203 567 BRM_2 367 1308 BRM_3 435 509 As you can see field1 of line1 is same as field2 of line2 and so that field BRM_1 should be place in object1 and BRM_2 and BRM_3 should be placed in object2. So the final numbers of object1 is 1 and object2 is 2. Thanks in advance.. Upendra -- http://mail.python.org/mailman/listinfo/python-list
Re: how to compare two fields in python
The data was sorted and so duplicates will not appear anywhere in the dataframe. The values does not have significance and can be ignored safely.

Also, do the values that follow have any significance for this, or are they just noise to be ignored? -tkc -- http://mail.python.org/mailman/listinfo/python-list
