[Tutor] A Python program to Summarise weather results?
Hi, We have a spreadsheet from a local weather station.it summarises the amount of rainfall per day since 1863. http://www.bom.gov.au/jsp/ncc/cdio/weatherData/av?p_nccObsCode=136&p_display_type=dailyDataFile&p_startYear=1863&p_c=-1249186659&p_stn_num=079028 We'd love to be able to summarise this into years eg. Total rainfall of 1863, 1864 all the way through to 2018. Would Python be able to do this using the csv file?

[Tutor] localhosting
I'm trying to implement a local host. My instructions tell me to type the following command in the command line, make sure I'm in the "www" folder (which I am and not a subfolder, although there is a subfolder "cgi-bin") and then run this: python3 -m http.server --cgi 8000 I'm running Anaconda in Windows 10. I get an error: 'python3' is not recognized as an internal or external command, operable program or batch file. But this is the folder that I thought Python 3.6 was in. I tried Windows PowerShell and received this error message: python3 : The term 'python3' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. So how do I correct this? I suspect python3 isn't in this folder. I know I have python3 because I run python3.6 shell practically every day. I've looked in the Program Files folder, came up empty as far as python is concerned, but I don't know where else to look? Or if this is not the correct forum, can you please (re)direct me to the correct one? Thank you. -- Roger Lea Scherer 623.255.7719 *Strengths:* Input, Strategic, Responsibility, Learner, Ideation ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

If so have you trioed working on your files on the PC and only ftp'ing the "working" files to Solaris? At the very least cygwin would allow you to run X Windows on your PC and display the Solaris programs on your PC screen. It should also provide tools like rsync and ssh at the PC end. (As per Camerons mail, rsync is by far the best tool for syncing file systems across machines) > This process has changed all of the Unix file permissions That is inherent in using version control systems. > So before I can do anything further I must go through all of these > files and change their permissions to the values I need them to be. > This is quite tedious and error prone.

Not that odd in a corporate environment, I was still using Python 1.3 in 2002 for similar reasons on one of our work servers. But there is a 50/5-0 chance the latest Solaris upgrade will have included rsync.

It is likely that Python is not in your system PATH. You need to find out where it is installed and add it. In a standard Python install it would either be in C:\PROGRAM FILES\PYTHON or C:\PYTHON But Anaconda (version please?) could use its own path such as C:\ANACONDA\PYTHON > So how do I correct this?

This is OK, although you might try the Anaconda folks too since they will know more about how/where Anaconda installs python and sets up[ default paths. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Python has powerful tools to make this concise, like csv.DictReader() and itertools.groupby(), or -- even more highlevel -- pandas. But you want to learn Python, don't you? Therefore I recommend that you try to solve this with just open() and a for loop to read the lines, and the str.split() method to break the lines into fields. With 'if ' you check whether the year has changed so that you need to print the current total and reset the total rainfall. Give it a try, see how far you get, and we'll help you over the obstacles once you can present some rudimentary code. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

How you process it is then up to you. If its only the year field you want to filter by consider loading it into a dictionary using the year as the key. Personally, I'd put it into a SQLite database and use SQL to do the report generation (either from Python or via the SQLIte command line tool). That lets you explore the data in many more interesting ways. But learning SQL might be a step too far at this juncture. :-) -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Ah, interesting. I've never found a VC system that preserved permissions. Usually they zap everything to read-only on first export. Then change them to read-write when you check out etc, then back to read-only on checkin. I never assume anything about permissions from a VC system and always set them as they should be in the make file or installer. > But there's also the issue of Windows permissions versus UNIX permissions. Very true aqnd that varies by file system too.

Several things that could help: you can ask python itself to tell you where it is, since you say python works for you. >>> import sys >>> print(sys.executable) the standard Windows python defaults to a "user install", so it could be in a place like {yourhomdirectory}/AppData/Local/Programs/Python Anaconda, as Alan says, likely puts it somewhere different. Python 3 isn't named python3 on Windows unless you take steps to make it so, it's just called python. So modify your instructions accordingly. Also on Windows, if it was installed, there is a separate thing called the Python Launcher, which lets you run the command "py" which typically gets put in a place that is always found, and avoids the fiddling with getting Python itself into your PATH. But I'm unsure whether the Anaconda install actually installs that. You could try... just type: py ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
