Comparing lists

Hi all, anybody can point me to a description of how the default comparison of list objects (or other iterables) works? Apparently l1 < l2 is equivalent to all ( x < y for x,y in zip( l1, l2) ), has is shown in the following tests, but I can't find it described anywhere: >>> [1,2,3] < [1,3,2

Extract value and average

would like to extract values corresponding to variable DIHED (here 4660.1650) and getting also the mean value from all DIHED. Thanks for giving a possible attack francesco pietra NSTEP = 1000 TIME(PS) = 152.000 TEMP(K) = 298.54 PRESS =89.4 Etot = -134965.2

Fwd: Extract value and average

t; yields a dictionary for each item in the input file. You can pull out whichever value(s) you want to manipulate. I recognize now that I did not define "block" correctly. The EWALD line, although separated by a blank line, makes part of the block. The layout of all ot

How to find info about python 3.x extension module availability?

Hi all, is there any site that reports the current porting (to Python 3.x) status of the main non-standard extension modules (such as pygtk, pywin32, wxpython, ...) ? I think such information would be very useful for people - like me - which are tryiing to decide how/when/if to port existing scrip

Recipes for trace statements inside python programs?

Hi all, as many - I think - python programmers, I find muself debugging my scripts by placing print statements in strategic places rather than using the python debugger, and commenting/uncommenting them according to myy deugging needs. After a time, these prints staements start to evolving in som

Sorry, hit the send button by mistake ... The definition of the trace function should be like: if __debug__ : def TRACE(*args): if trace_enabled(): print "TRACE(%s) : %s " % ( context(), " ".join( str(x) for x in args ) ) else : # optimazed code, only a func

Unexpected behaviour of inner functions/ decorators

Hi all, I found a strange (for me) behaviour of inner function. If I execute the following code: # file in_f.py --- def dec_f(f): def inner_f(): if f.enabled: f() return inner_f @dec_f def funct(): print "Ciao" funct.enabled = True funct() # end of file
