is practice add placeholder columns when creating database table millions of rows, in case schema gets changed later? more efficient rename column insert new one? there many problems adding "placeholder" columns table. these columns may take useless space, , appear "sloppy". you may create many columns now, , have columns never used. you may not create enough columns now, , have end creating more anyways. you don't know column data types @ time. always remember if column needs added @ later date , not used of current rows in table, can still keep table normalized creating smaller table holds information, link them using primary key. let me know if have questions this. hope helps!

i unable key events /dev/input/event1. i'm able filter out output absolute x , y touch coordinates event code 53 , 54. i'm confused why there's no output event code 1 when type on soft keyboard. want know key user presses , how pressure. hope understand problem. i'm on rooted samsung galaxy s4. because soft keyboard doesn't work that. isn't part of os, application. keyboard app given touch events, , call java functions tell main app pressed. doesn't go through hardware input channels @ after press. os doesn't know keys where, ever. most keyboards don't generate key events- generate word @ time output via committext. basically, can't want in way want. way know keys pressed, without altering os, on other side of inputconnection processing commands inputmethodservice (keyboard).

i'd have custom getter , setter method object wraps map . somehow when use arrays key getter behaves equal when have same values. though 2 different references. (tested in ff , chrome). jsfiddle var cons = function (){ this.data = new map(); }; cons.prototype.initialisegetterandsetter = function initialisegetterandsetter(prop){ object.defineproperty(this, prop, { get: function(){ return this.data.get(prop); }, set: function(val){ this.data.set(prop, val); } }); }; var obj = new cons(); var arr1 = [1]; var arr2 = [1]; var arr3 = [2]; obj.initialisegetterandsetter(arr1); obj[arr1] = 1; document.getelementbyid('box1').innertext = obj[arr1]; // 1 expected document.getelementbyid('box2').innertext = obj[arr2]; // expected undefined got 1 document.getelementbyid('box3').innertext = obj[arr3]; // undefined expected as can see doesn't matter if pass getter same reference expecting. checks if has same values kind...

df2= pd.dataframe(df1.iloc[:, [n n in random.sample(range(1, 7), 3)]]) returns df1 rows , selected columns returns generic index 0,1,2,3..etc instead of returning datetime index of df1 want keep. tried: df2=df1.copy(deep=true) df2= pd.dataframe(data=none, columns=df1.columns, index=df1.index) df2= df1.iloc[:, [n n in random.sample(range(1, 7), 3)]] but not work... try this: df2 = pd.dataframe(df1.ix[:,random.sample(range(1,7),3)]) this give result wanted. df1 out[130]: 1 2 d nan 4.0 b 2.0 2.0 c 3.0 3.0 1.0 1.0 df1.ix[:,random.sample(range(0,2),2)] out[131]: 2 1 d 4.0 nan b 2.0 2.0 c 3.0 3.0 1.0 1.0 this randomly sample columns , returns them in df2. return rows of randomly sampled columns index in df1. edit- maxu has suggested, can use: df2 = df1.ix[:, random.sample(df.columns.tolist(), 3)].copy() instead of calling pd.dataframe() constructor.
