Re: [Tutor] IDLE problems
OK, so from Finder. In that case can you open a Terminal window and drag the python folder into the Terminal - that should navigate you to the same folder. Then try running IDLE by typing python ./idle.py At the terminal prompt. I meant to say that this will let you see any error messages from running IDLE. If you get any, post them here. Here's what I get: Last login: Wed Mar 7 11:27:19 on ttys000 MacBook-001FF3569577-4:~ fedka2$ /Applications/Python\ 3.2 -bash: /Applications/Python 3.2: is a directory MacBook-001FF3569577-4:~ fedka2$ python ./idle.py /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file './idle.py': [Errno 2] No such file or directory MacBook-001FF3569577-4:~ fedka2$ I don't seem to be getting a terminal prompt after dragging the folder into the shell??

Re: [Tutor] Question about writing to Excel with slavic characters
Hi, I have been trying to use that programme but without success. In Eclipse you usually create new project in two steps, first you create new Pydev project, then inside you create new Pydev module. I have created new project and new module 'crosstabs', where I want to read spss file. My programme is the module. Now I have put this ReaderWriter programme into the same Pydev project as a another new module called 'rw' and then imported it into my module 'crosstabs' with import rw from rw import SavReader I don't even know, if I did that correctly. Actually I don't even know how to implement that programme. I put the recommended code savFileName = C:/dropbox/Exc_MarkoL_Zenel/Valicon/crosstabs/Tabela/ipk108_kosovo_data_finale_c1-1.sav with SavReader(savFileName) as sav: header = sav.next() for line in sav: process(line) but I am get errors I have however managed to compile the programme in the module, I just had to comment more than 20 lines (because of that problem with employee data.sav ). I also don't know, if it was right to comment all those lines. Without commenting them I can't even compile the module. Maybe someone can tell me, how to actually implement that programme? Where to put it in my Eclipse? Is this programm ethe best way to read spss with Python?

The memisc package also has a function to read .sav files. The big advantage of that function is that you can select rows and columns prior to actually reading the data into memory. If you're just using R and Rpy to read .sav files, you could also consider using a Python program that I wrote a while ago: http://code.activestate.com/recipes/577811-python-reader-writer-for-spss-sav-files-linux-mac-/ It runs on Windows, Mac and Linux and requires no installation of spss.

Re: [Tutor] misunderstanding any
a = tuple(range(10)) b = tuple(reversed(a)) any(a) in b True any(b) in a True any((a,b)) in (a,b) False # I think I understand this now, but I must admit it looks confusing! I just want to clarify some things. 'any(a) in b' evaluates any(a) before it evaluates 'x in b'. So in essence 'any(a) in b' is equivalent to 'True in b'. The reason why you get True in the first two cases is because of Python's history where there were no bool types (I could be wrong on this). At the very least bool types inherit from integer in a common practice from older languages like C. Hopefully some of my samples will help explain my point. a = range(10) b = tuple( reversed( a ) ) any(a) # Any non-zero value equates to true True any(a) in b # True == 1 True True in b # True == 1 True any(b) # Any non-zero value equates to true True True in a # True == 1 True True == 1 # Proof that True == 1 True False == 0 # Proof that False == 0 True any( (a,b) ) # many non-zero values True a = range( 10,20 ) # create a list without 1 b = tuple( reversed( a ) ) any( a ) # still contains non-zero values True any( a ) in b # b is missing the value 1 and therefore missing True False any( b ) # still contains non-zero values True any (b ) in a # a is missing the value 1 and therefore missing True False any( (a,b) ) # still contains non-zero values True any ( (a,b) ) in ( a,b ) # a and b is missing the value 1 False any ( (a,b) ) in ( a,b, 1 ) # 1 == True True Thinking that if *any* of the tuples is in fruit_type(a list of tuples), then it should return True. What you want is not any, but probably filter or any + map. c = zip( a, b ) c [(10, 19), (11, 18), (12, 17), (13, 16), (14, 15), (15, 14), (16, 13), (17, 12), (18, 11), (19, 10)] d = ( 11, 18 ) filter( lambda x: d == x, c ) [(11, 18)] if filter( lambda x: d == x, c ): ... print 'True' ...
