python - Appending column from one tsv file to another (unix) -


i have 2 tsv files, each headers , columns. file has headers: sampleid & rawreads, fileb has headers: sampleid & readspost. want append readspost filea data lines correct sampleid.

my original plan in python using dictionaries keys being sampleids. however, there must easier way in bash!

any great!

use join , full outer join (or other type of join): 

>cat test.txt test2.txt sampleid  rawreads 1         18 2         15 5         21 7         7 sampleid     readspost 1            yes 3            no 4            yes 5            yes  > join -a1 -a2 test.txt test2.txt sampleid rawreads readspost 1 18 yes 2 15 3 no 4 yes 5 21 yes 7 7

note: -a argument prints lines file aren't joined. full outer join, print lines both files, exemplified.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -
