I ran into this "problem" with Python scoping. I know that Python uses statical scoping but that doesn't really work that well with the lambda keyword.

What does the following program output?
code:
a = []
for i in xrange(5):
	a.append(lambda x: i + x)

print a[1](1)
a) 2
b) 5
c) -1

Answer: b) 5

the i is stored in the outer scope, and not copied into the lambda, so i keeps the value from exiting the loop.

code:

a = []
for i in xrange(5):
	a.append(lambda x, i=i: i + x)

print a[1](1)

happy now ?

these loop 4 times so i will he 4 after the loop completes

code:

to be honest, this makes sense
anonymous functions should not store unless explicitly declared

Elder Postsman: Aug 30, 2000; i used hot bot to search for "teens"

i wrote some python today, can y'all tell me how bad it is (it's bad because it's python but i mean besides that)

this first one takes a qa flag layer like this:

code:

OBJECTID	SHAPE	TYPE	COMMENTS	FEATURECLASS		FEAT_OID	STATUS
1		POINT	0	Disconnected	SupportStructure	1234		0
2		POINT	0	Disconnected	Fuse			4532		0
3		POINT	0	Disconnected	Switch			8633		0
4		POINT	0	Disconnected	SupportStructure	2523		0
5		POINT	0	Disconnected	Transformer		523		0

and selects the flagged features and outputs the selection to an xml. i even used elementtree to make the xml in a not-stupid way like i was before

Python code:

import arcpy, xml.etree.cElementTree as et
arcpy.env.overwriteOutput = True

savePath = arcpy.GetParameterAsText(0)
QAException = arcpy.GetParameterAsText(1)

outFile = open(savePath, 'w')

def getValueList(flag, field):
    values = set()
    rows = arcpy.SearchCursor(flag)
    for row in rows:
        values.add(row.getValue(field))
    valueslist = list(values)
    return valueslist

root = et.Element("Selection")

featureList = getValueList(QAException, "FEATURECLASS")

for featurename in featureList:
    QAFeature = arcpy.MakeFeatureLayer_management(QAException, "QAFeatureLayer", "FeatureClass = '" + str(featurename) + "'")
    fcline = et.SubElement(root, "FeatureClass", {"name":str(featurename), "oid_field":"ObjectID"})
    featoidlist = getValueList(QAFeature, "FEAT_OID")
    if len(featoidlist) > 1:
        qry = "OBJECTID in " + str(tuple(featoidlist))
    else:
        qry = "OBJECTID = " + str(featoidlist[0])
    for featoid in featoidlist:
        fline = et.SubElement(fcline, "Feature", {"oid":str(featoid)})    
    arcpy.SelectLayerByAttribute_management(featurename, "NEW_SELECTION", qry)

et.ElementTree(root).write(outFile)

so that would select those features from those featureclasses, and put out an xml like

code:

<Selection>
	<FeatureClass name="SupportStructure" oid_field="OBJECTID">
		<Feature oid="1234" />
		<Feature oid="2423" />
	</FeatureClass>
	<FeatureClass name="Fuse" oid_field="OBJECTID">
		<Feature oid="4532" />
	</FeatureClass>
	<FeatureClass name="Switch" oid_field="OBJECTID">
		<Feature oid="8633" />
	</FeatureClass>
	<FeatureClass name="Transformer" oid_field="OBJECTID">
		<Feature oid="523" />
	</FeatureClass>
</Selection>

and then this one takes that xml and selects those features. so for example you can recreate that selection on another computer or whatever

Python code:

import arcpy, xml.etree.cElementTree as et

xmlfile = arcpy.GetParameterAsText(0)

content = et.ElementTree(file=xmlfile)
selection = content.getroot()

for featureclass in selection:
    currentfeature = featureclass.attrib.get('name')
    oidlist = []
    for feature in featureclass:
        oidlist.append(feature.attrib.get('oid'))
        if len(oidlist) > 1:
            qry = "OBJECTID in " + str(tuple(oidlist)).replace("'", "")
        else:
            qry = "OBJECTID = " + str(oidlist[0]).replace("'", "")
    arcpy.SelectLayerByAttribute_management(currentfeature, "NEW_SELECTION", qry)

honestly, it looks generally fine. not familiar with arcpy, but nothing there looks obviously wrong.

I'd probably rewrite getValueList() as:

Python code:

eh, it's pretty idiomatic. grab an iterator, map a single function on it, feed that into a set and then into a list. it's admittedly borderline - one more operation, and I'd definitely want to split it onto multiple lines - but I think it's ok.

actually, on further consideration, this is probably about right:

    valueSet = set(row.getValue(field) for row in arcpy.SearchCursor(flag))

Jerry SanDisky posted:

yes, I literally did two posts up from the one you quoted. but then I decided that it was too many things going on in one line, and split it up to make it easier to read.

dur's original code was

Python code:

def getValueList(flag, field):
    values = set()
    rows = arcpy.SearchCursor(flag)
    for row in rows:
        values.add(row.getValue(field))
    valueslist = list(values)
    return valueslist

but that was on too many lines, and actually made it harder to read. like writing

Java code:

int i;
i = 0;
int bound = arr.length - 1
while (i < bound) {
    arr[i] = arr[i+1];
    i++;
}

instead of

Java code:

for (int i = 0; i < arr.length - 1; i++)
    arr[i] = arr[i+1];

it's a balance, and admittedly something of a personal judgment - different people will have different opinions on what's easy to read. (some people still believe in the 80-character limit!) but I think I'm right, and that's what matters.

PleasingFungus: Oct 10, 2012; idiot asshole bitch who should fuck off

just noticed something else:

Python code:

    for feature in featureclass:
        oidlist.append(feature.attrib.get('oid'))
        if len(oidlist) > 1:
            qry = "OBJECTID in " + str(tuple(oidlist)).replace("'", "")
        else:
            qry = "OBJECTID = " + str(oidlist[0]).replace("'", "")
    arcpy.SelectLayerByAttribute_management(currentfeature, "NEW_SELECTION", qry)

the 'if len(oidlist)/else' block should probably be decremented one setp; no reason to do it until you've finished building oidlist. also... are you turning oidlist into a tuple so you get parens instead of square brackets? :allears:

actually, now that I'm looking at it

Python code:

...
    def feature_to_oidstr(feature):
        oid = feature.attrib.get('oid')
        return str(oid).replace("'", '')
    oidstrlist = [feature_to_oidstr(feature) for feature in featureclass]

    if len(oidstrlist) > 1:
        qry = "OBJECTID in ({})".format(','.join(oidstrlist))
    else:
        qry = "OBJECTID = " + oidstrlist[0] #this will throw an exception if there are no oids in the featureclass

    arcpy.SelectLayerByAttribute_management(currentfeature, "NEW_SELECTION", qry)

more lines, but clears up some silliness with the strings slightly, maybe.

honestly I just like playing with python and list comprehensions. I admit it.

I thought that at first, but then I noticed this bit

Python code:

that is extremely silly, and certainly bad practice, but I can't bring myself to be upset about it. (the teddy in your av probably helps. :3:

)

the post you quoted suggests one way to be a little more explicit about what you're doing vis-a-vis string formatting:

Python code:

            qry = "OBJECTID in ({})".format(','.join(oidstrlist))

build a comma-separated list of elements, then drop 'em between parens. it's the same result as the tuple approach, just expresses your intent more clearly in code, rather than indirectly indicating it by switching data structures.

the comprehension idiom is a strong thing in python (it's super fast) and in the case where it might have too many for loops and ifs you can just break it in different lines and it still looks very readable!

with that said I couldn't convince anyone irl of how great comprehensions are, even after I show this example from Peter Norvig's code.

everybody is exactly like "I don't need this perl poo poo in my python"

as someone who doesn't use python that syntax looks awful

i can't tell what i'm looking at (did you mess up the indentation or something?)

can someone explainn to me

as someone who uses python & loves list comprehensions, I am baffled and faintly horrified. that code is incomprehensible.

I'll second the question re indentation.

I think it's God's own code

you can tell because it's ineffable

googling finds context: it's a fragment of a program that solves the Zebra Puzzle

specifically, it's a fragment of one of these programs; though notably, these two are also both incomplete.

still looking at indentation. I tried a few different variants, but they were clearly both (a) wrong and (b) broke tables.

okay, got it, maybe. it iterates over assignments of (house number) permutations to elements, filtering out impossibilities at each stage; at the end, an iterator is returned that only yields one element, the solution.

Python code:

return next(
	(
		(
			(
				(
					(WATER, ZEBRA) for (red, green, ivory, yellow, blue) in c(orderings) if imright(green, ivory)
				) for (Englishman, Spaniard, Ukranian, Japanese, Norwegian) in c(orderings) if Englishman is red if Norwegian is first if nextto(Norwegian, blue)
			) for (coffee, tea, milk, oj, WATER) in c(orderings) if coffee is green if Ukranian is tea if milk is middle
		) for (OldGold, Kools, Chesterfields, LuckyStrike, Parliaments) in c(orderings) if Kools is yellow if LuckyStrike is oj if Japanese is Parliaments
	) for (dog, snails, fox, horse, ZEBRA) in c(orderings) if Spaniard is dog if OldGold is snails if nextto(Chesterfields, fox) if nextto(Kools, horse)
)

flow proceeds first from bottom to top (the bottom/outermost iterator requesting a yield from the one above, etc), then top to bottom repeatedly (as the top/innermost iterator yields a permutation, which proceeds downward, matching with other permutations until a filter rejects, at which point control steps up a level, etc); the top iterator yields many times, the bottom iterator only once.

in the end, a pruned subset of P(5)^5 = ~25E9 possibilities are examined; the code is from an attempt to minimize on possibilities examined.

that only took 35 minutes to figure out. good code!

oh well

it looks good to me and understandable for those kinds of brute-force things and also very convenient to tinker and reorder the loops. it's not very natural at first but I guess I got used with the bottom-up flow from comprehensions? something huge like this rarely came up for me besides challenge problems though

but yeah I guess I gotta rethink this stuff
