i want calculate group specific ratio gathered 2 datasets. 2 dataframes read database with leases = pd.read_sql_query(sql, connection) sales = pd.read_sql_query(sql, connection) one real estate offered sale, other rented objects. group both of them city , category i'm interested in: leasegroups = leases.groupby(['idconjugate', "city"]) salegroups = sales.groupby(['idconjugate', "city"]) now want know ratio between cheapest rental object per category , city , expensively sold object obtain lower bound possible return: minlease = leasegroups['price'].min() maxsale = salegroups['price'].max() ratios = minlease*12/maxsale i output like: category - city: ratio cannot access ratio object city nor category. tried creating new dataframe with: newframe = pd.dataframe({"minleases" : minlease,"maxsales" : maxsale,"ratios" : ratios}) newframe = newframe.loc[newframe['ratios'].notnull()]

my questions based upon first answer this question . want count elements key, how that? example = sc.parallelize([(alpha, u'd'), (alpha, u'd'), (beta, u'e'), (gamma, u'f')]) abc=example.groupbykey().map(lambda x : (x[0], list(x[1]))).collect() # gives [(alpha, [u'd', u'd']), (beta, [u'e']), (gamma, [u'f'])] i want output below alpha:2,beta:1, gamma:1 i came know answer below. why complex? there simpler answer? s contain key + values? why cannot len(s)-1 subtracting 1 remove key s[0] map(lambda s: (s[0], len(list(set(s[1]))))) well, not complex. need here yet word count: from operator import add example.map(lambda x: (x[0], 1)).reducebykey(add) if plan collect can countbykey : example.countbykey() you don't want use groupbykey here assuming there hidden reason apply after all: example.groupbykey().mapvalues(len) why len(s) - 1 doesn't work? because example pairwise rdd or in

when build c# code in visual studio 2015 using default compiler (nothing unusual project), output in output window looks bit this. (the actual width isn't representative, i've replaced rather long path xxx .) 1>xxx(402,13,402,16): error cs1955: non-invocable member 'lo 1>g' cannot used method. 1>xxx(424,25,424,28): error cs1955: non-invocable member 'lo 1>g' cannot used method. presumably compiler printing non-invocable member 'log' cannot used method , , something, somewhere, stepping in , popping newlines in (at column 120 in practice - mentioned, column counts in example output unrepresentative). can stop this? if so, how? i'd prefer messages printed out newlines in natural places, can use output window's word wrap functionality. after open package manager console, build output starts become wrapped above. the fix appears to restart visual studio.

lets have rdd -> (string, date, int) [("sam", 02-25-2016, 2), ("sam",02-14-2016, 4), ("pam",03-16-2016, 1), ("pam",02-16-2016, 5)] and want convert list -> [("sam", 02-14-2016, 4), ("pam",02-16-2016, 5)] where value record date min each key. best way this? i assume since tagged question being related spark mean rdd opposed list. making record 2 tuple, key first element allow use reducebykey method, this: rdd .map(t => (t._1, (t._2, t._3)) .reducebykey((a, b) => if (a._1 < b._1) else b) .map(t => (t._1, t._2._1, t._2._2)) alternatively, using pattern matching clarity: (i find _* accessors tuples bit confusing read) rdd .map {case (name, date, value) => (name, (date, value))} .reducebykey((a, b) => (a, b) match { case ((adate, aval), (bdate, bval)) => if (adate < bdate) else b }) .map {case (name, (date, value)) => (name, date, value)} re

i using bean validation constraints validate class instances @ run time. have many dtos each has multiple fields common constraint. want add constraint class applies properties of class.

i have file like: @hwi abcde + @hwi7 efsa + ???=af gtey@jf gvtawm i want keep strings ( remove contains symbol ) i tried : import numpy np arr = np.genfromtxt(f, dtype=str) line in np.nditer(arr): if np.core.defchararray.isupper(line) , not '@?=;?+' in line: print line but gives : @hwi abcde @hwi7 efsa ???=af gtey@jf gvtawm and expecting: abcde efsa gvtawm i want use numpy , not commands regex or similar. this solution : import numpy np arr = np.genfromtxt('text.txt', dtype=str) test = np.core.defchararray.isalpha(arr) #create mask : true = str , false = not str print arr[test] #use mask on arr , print values don't use if numpy ! have indexing ;) i : ['abcde' 'efsa' 'gvtawm']
