python - Assign Raster band to variable name in Loop - "can't assign" error -


i want write 2 nested loops iterate on rgb bands of series of 8 jpg images. later on these images shall combined 1 array channel channel, each array of channels first has have proper name:

for colorband in [1, 2, 3]:         eighth in range(0,8):             rastername="20140525-16-20-00_full_"+str(eighth)+"_0.jpg"             raster =gdal.open(rastername)             band = raster.getrasterband(colorband)             "eighth_"+str(eighth)+"_"+colorband = band.readasarray()

unfortunately, returns "can't assign function call" error. couldn't find proper answer how solve in other questions. can help?

the error in line:

"eighth_"+str(eighth)+"_"+colorband = band.readasarray()

it appears trying create variable name , assign result of band.readasarray().

you create dictionary, color_dict , make "eighth_"+str(eighth)+"_"+colorband key , use assign value of band.readasarray(). i.e.,

color_dict = {} color_dict["eighth_"+str(eighth)+"_"+colorband] = band.readasarray()

later in code can access data color_dict["eighth_"+str(eighth)+"_"+colorband]

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...
