R Shiny - resize numericInput box -


i have basic shiny app.

ui.r:

library(shiny)  shinyui(fluidpage(   titlepanel("average run length simulation"),    fluidrow(     tabsetpanel(       tabpanel("shewhart v. shewhart",         fluidrow(           column(4,"rule"),           column(2,"group 1"),           column(2,"group 2")           ),         fluidrow(           column(4,"1 point more k sigma away mean"),           column(2,                  checkboxinput("svsg1r1",label=" ",value=f),                  numericinput("svsg1k1",label=" ",value=3,min=1,step=1)                  ),           column(2,                  checkboxinput("svsg2r1",label=" ",value=f),                  numericinput("svsg2k1",label=" ",value=3,min=1,step=1)                  )           )         )       )     ) ))

the server.r file basic 1 created rstudio in new project.

what want tabular layout of widget elements, but, don't think i'll without lot of work , isn't worth it. so, instead, want reduce width of numericinput() boxes akin the size attribute of <input> element in html form.

how in shiny? there standard way apply css/html specifics particular elements?

this works, though it's global css , i'd rather have element specific. added inside fluidpage() element in ui.r , resized both boxes.

tags$head( tags$style(html("   input[type=\"number\"] {     width: 100px;   }  ")) )

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
