i have pandas dataframe has 2 columns 1 of columns list of dates in format: '4-dec-14' other column list of numbers. want plot graph dates on x-axis , numbers correspond date on y-axis. either scatter plot or line graph. trying follow tutorial on matplotlib http://matplotlib.org/users/recipes.html 'fixing common date annoyances' not accept date format. when try using plot function returns error: valueerror: invalid literal float(): 4-dec-14 . how change date format work. or there other way can plot dataframe. thanks you should first convert strings in date column, actual datetime values: df['date'] = pd.to_datetime(df['date']) then can plot it, either setting date index: df = df.set_index('date') df['y'].plot() or specifying x , y in plot: df.plot(x='date', y='y')

let's have api provides array of strings example, , array might larger physical memory. can jvm page part of array , bring disk traverse it? or array "atomic" data type can't partially paged? assume linked list answer easier since of nodes can paged transparently , retrieved on page fault, wonder if jvm (or if major oss @ all) allow paging part of large continuous array. nope. jvm can't this. but write implementation of list handle transparently, storing values disk or in database, , retrieving them necessary. an operating system can page bits of memory disk you, want careful relying on work efficiently. whether work without grinding halt rather depends on you're doing. involves accessing random entries in quick succession not cope being paged out. hash table, instance, doesn't perform in context.

i'm trying call 3 different tables @ once. table a has general data. table td & dmd have specific data data points. my call (simplified) looks this. select a.*, td.*, dmd.* activities a, tweet_activity_data td, direct_message_activity_data dmd a.activity_id in (1,2,3,4,5) , a.activity_id = dmd.id , a.activity_id = td.tweet_id those last 2 lines i'm having trouble think. i need things line in response , produces no results. am 'allowed' use 2 joins in sql call? yes, join tables use join , on keyword. specifically, stuff in clause end on clauses, telling query how join tables. query select a.*, td.*, dmd.* activities join tweet_activity_data td on a.activity_id = td.tweet_id join direct_message_activity_data dmd on , a.activity_id = dmd.id a.activity_id in (1,2,3,4,5)

the result of query need create return single row. data need pull comes 2 tables without relational columns. second table has additional rows added once per year i'll construct query via php necessary. i know how use sql sub-selects i'm not sure how select multiple columns from second table when there no relational data in performance oriented/dynamic way. here static example use multiple sub-selects visualize i'm trying do... select t1.a, t1.b, t1.c, (select t2.d table2) d, (select t2.e table2) e, (select t2.f table2) f, (select t2.g table2) g, t1.h, t1.i table1 t1; how dynamically , efficiently pull multiple columns second table has no relational columns first table? i not want create second separate query cheap solution, have some impact on performance , worst of wouldn't expand understanding of sql. sounds need cartesian join (no join) -- multiply values (ie, if table 1 has 100 rows , table 2 has 10 rows, you'll return 1000 row...

this question has answer here: loop “forgets” remove items [duplicate] 10 answers i learn python.i have problem here.it simple code,but don't know why result unexpected. here code: a=[1,2,3,4,6,7,'dd','ss','gg','oo',8] in a: b in range(10): if i==b: a.remove(i) print i want delete number in a. expecting result a=['dd','ss','gg','00'] result : [2, 4, 7, 'dd', 'ss', 'gg', 'oo'] i cannot understand why result this. can me? thank you! try remove integer list = [x x in if not isinstance(x, int)]

i have design database. , finding entities , relationships. every relationships seems have many-to-many relationships. instance, in case: 1) staff manages client here staff can manage 0 or more client. similarly, client managed 1 or more client. 2) client orders buy stock here client can order zero, 1 or more stock buy , stock can ordered zero, 1 or more client. 3) client orders sell stock here client can order zero, 1 or more stock sell , stock can ordered zero, 1 or more client sell. these of examples of situation. , confused how separate these relationships. there other numerous cases these in scenario. , having difficulty conceptualize design. so, please enlighten me regarding situation. it seems there's quite lot system developing , presumably there requirements haven't mentioned isn't possible come complete answer. of following "conceptualize design" describe it. 1) common scenario , there's pretty standard way of dealing t...

i confused how implement simple q_learning algorithm. referring nice docummentation: http://artint.info/html/artint_265.html . the given formula is q[s,a] ←q[s,a] + α(r+ γmaxa' q[s',a'] - q[s,a]) the problem states unknown because trying learn flappybird's successful moves. q[s,a] need know value of q[s',a'] if don't know next state, how q function? assuming state described distance between bird , nearest pipe, how compute current q function? thank help! s' current state. s previous state. max_a' q[s', a'] value of best action current state.
