[issue30362] Launcher add list and list with paths options

Steve Barnes added the comment: If this option is added into the py launcher it will make it usable for a multipy script/utility that would call py -0 to get a list of installed pythons and then call it for each of the returned versions with the remaining parameters. I personally would find

[issue30362] Launcher add list and list with paths options

Paul Moore added the comment: I'm also not a fan of the -0 option. I'm OK with the ability to list available interpreters, but there's nothing about -0 as an option that says to me that's what it's for. I'm not a huge fan of including the list in the standard help, as py -h already generates

Steve Barnes added the comment: Latest push still has -0 and -0p options for explicit discovery but also defaults to displaying the list if the requested version is not found. (As well as the default python being marked with a trailing * - I have also removed the less than helpful "default

[issue30362] Launcher add list and list with paths options

Steve Dower added the comment: I agree with printing discovered interpreters in help text - not a fan of the -0 option. IDEs should probably go directly to the registry to discover Python installations (or use pep514tools), since the launcher will only launch a subset of them (i.e. per-user

Eryk Sun added the comment: I'm -0 on the "-0" option, but I think printing the list of registered Python installations would be useful in the --help text and when the launcher fails to find a requested version. -- nosy: +eryksun ___ Python tracker

[issue30362] Launcher add list and list with paths options

Steve Barnes added the comment: @terry.reedy - Very good points and I like the shortness of -0 note that there is already an accepted change to allow -x.y-64 to specifically require the 64 bit versions so we don't need the complex logic to distinguish cases where -x.y will run 32 bit because

[issue30362] Launcher add list and list with paths options

Terry J. Reedy added the comment: py already has the -number option space. To avoid conflict, use -0 (zero). I think only one option is needed -- print 'x.y path' for each binary it can find and run. 'x.y' should be the exact option needed to start the particular binary. This enhancement

[issue30362] Launcher add list and list with paths options

about dropping the short flags, (-l & -L), and making the long flags more launcher specific, i.e. --launcher-list and --launcher-list-paths spring to mind. I really do think that this change would be really useful, e.g. in the short form to generate a list of installed targets that might all

[issue30362] Launcher add list and list with paths options

Steve Dower added the comment: The problem with taking more command line options is that we prevent real Python from ever using those options (or we end up with obscure rules like the "-3" one). Perhaps you'd be interested in using/contributing to my pep514tools project:

Re: List of paths

Here's a tricky case that doesn't show up in your example: In each case above, the directory names are distinct. how about: ['/desk', '/desk/ethanallen', '/desk/ikea', '/desktop', /desktop/pc', '/desktop/mac'] Should the answer be ['/desk'] or ['/desk', '/desktop'] ? Hi Scott good point.

List of paths

Dear Python developers I have the following (sorted) list. ['/notebook', '/notebook/mac', '/notebook/mac/macbook', '/notebook/mac/macbookpro', '/notebook/pc', '/notebook/pc/lenovo', '/notebook/pc/hp', '/notebook/pc/sony', '/desktop', '/desktop/pc/dell', '/desktop/mac/imac',

You could use the followingm, where the_list is your list. (I'm new to python so there might be a better way): toremove = [] for x in the_list: for y in the_list: if y.startswith(x) and y != x: toremove.append(y) difference = filter(lambda x:x not

May be not so much pythonic, but works for i in range(len(q)): for x in q[i:]: if x.startswith(q[i]) and x!=q[i]: q.remove(x) ...but works fine. Thanks, Eugene. Also thanks to Andrew. Your example works fine, too. Thanks to remind me of the 'yield' statement! ;-)
