The accepted solution also works in julia Jupyter/IJulia with the following modifications:

display("text/html", """<script>
code_show=true; 
function code_toggle() {
 if (code_show){
 \$("div.input").hide();
 } else {
 \$("div.input").show();
 }
 code_show = !code_show
} 
\$( document ).ready(code_toggle);
</script>
<form action="javascript:code_toggle()"><input type="submit" value="Click here to toggle on/off the raw code."></form>""")

note in particular:

use the display function
escape the $ sign (otherwise seen as a variable)

Here is a nice article  the same one  Ken posted  on how to polish up Jpuyter  the new IPython  notebooks for presentation  There are countless ways to extend Jupyter using JS  HTML  and CSS  including the ability to communicate with the notebook s python kernel from javascript  There are magic decorators for   HTML and   javascript so you can just do something like this in a cell by itself     HTML  lt script gt    function code toggle         if  code shown            div input   hide  500              toggleButton   val  Show Code         else            div input   show  500              toggleButton   val  Hide Code             code shown    code shown           document   ready function        code shown false         div input   hide          lt  script gt   lt form action  javascript code toggle    gt  lt input type  submit  id  toggleButton  value  Show Code  gt  lt  form gt    I can also vouch Chris s methods work in jupyter 4 X X

This can be done using an IPython ToggleButton widget and a little bit of JavaScript  The following code should be placed into a code cell at the top of the document   import ipywidgets as widgets from IPython display import display  HTML  javascript functions    False   hide     True   show     button descriptions     False   Show code   True   Hide code     def toggle code state                Toggles the JavaScript show   hide   function on the div input element               output string     lt script gt     div input       lt  script gt       output args      javascript functions state        output          output string format  output args       display HTML output     def button action value                Calls the toggle code function and updates the button description               state   value new      toggle code state       value owner description   button descriptions state    state   False toggle code state   button   widgets ToggleButton state  description   button descriptions state   button observe button action   value    display button    This creates the following button to toggle showing hiding the code for the Jupyter Notebook  defaulted to the  hide  state     When set to the  show  state  you can then see the code for the Jupyter Notebook     As an aside  while much of this code should be placed at the beginning of the Notebook  the location of the toggle button is optional  Personally  I prefer to keep it at the bottom of the document  To do so  simply move the display button  line to a separate code cell at the bottom of the page

Paper  Printing or Saving as HTML  For those of you wishing to print to paper the outputs the above answers alone seem not to give a nice final output  However  taking  Max Masnick s code and adding the following allows one to print it on a full A4 page   from IPython display import display from IPython display import HTML import IPython core display as di  di display html   lt script gt jQuery function    if  jQuery  body notebook app   length    0    jQuery   input area   toggle    jQuery   prompt   toggle        lt  script gt    raw True   CSS       notebook div output subarea  max-width 100        changes output subarea width to 100   from 100  - 14ex  HTML   lt style gt    lt  style gt   format CSS     The reason for the indent is that the prompt section removed by Max Masnick means everything shifts to the left on output  This however did nothing for the maximum width of the output which was restricted to max-width 100 -14ex   This changes the max width of the output subarea to max-width 100

Many times  we need to hide some parts of codes while writing a long code  Example  - Just on clicking  quot Code show hide quot   we can hide 3 lines of codes   So here is the function that you need to define for partially hiding few part of codes and then call it whenever you want to hide some code  from IPython display import HTML  def hide toggle for next False       this cell    quot  quot  quot    div cell code cell rendered selected   quot  quot  quot    next cell   this cell     next         toggle text    Code show hide     text shown on toggle link     target cell   this cell    js hide current            if for next          target cell   next cell  toggle text      next cell           js hide current   this cell     find  quot div input quot   hide         js f name    code toggle     format str random randint 1 2  64         html    quot  quot  quot  lt script gt              function  f name       cell selector  find  div input   toggle                    js hide current           lt  script gt           lt a href  quot javascript  f name    quot  gt  toggle text  lt  a gt       quot  quot  quot  format f name js f name cell selector target cell js hide current js hide current  toggle text toggle text       return HTML html   Once we are ready with function definition  our next task is very easy  Just we need to call the function to hide show the code  print  quot Function for hiding the cell quot   hide toggle

For better display with printed document or a report  we need to remove the button as well  and the ability to show or hide certain code blocks  Here s what I use  simply copy-paste this to your first cell      This is a cell to hide code snippets from displaying   This must be at first cell   from IPython display import HTML  hide me      HTML     lt script gt  code show true   function code toggle       if  code show           div input   each function id          el     this  find   cm-variable first          if  id    0    el text       hide me               this  hide                           div output prompt   css  opacity   0       else          div input   each function id            this  show                   div output prompt   css  opacity   1         code show    code show       document   ready code toggle    lt  script gt   lt form action  javascript code toggle    gt  lt input style  opacity 0  type  submit  value  Click here to toggle on off the raw code   gt  lt  form gt        Then in your next cells   hide me print  this code will be hidden    and  print  this code will be shown

With all the solutions above even though you re hiding the code  you ll still get the   lt matplotlib lines Line2D at 0x128514278 gt   crap above your figure which you probably don t want   If you actually want to get rid of the input rather than just hiding it  I think  the cleanest solution is to save your figures to disk in hidden cells  and then just including the images in Markdown cells using e g    Caption  figure1 png

There is a nice solution provided  here that works well for notebooks exported to HTML  The website even links back here to this SO post  but I don t see Chris s solution here   Chris  where are you at     This is basically the same solution as the accepted answer from harshil  but it has the advantage of hiding the toggle code itself in the exported HTML  I also like that this approach avoids the need for the IPython HTML function    To implement this solution  add the following code to a  Raw NBConvert  cell at the top of your notebook    lt script gt    function code toggle         if  code shown            div input   hide  500              toggleButton   val  Show Code         else            div input   show  500              toggleButton   val  Hide Code             code shown    code shown           document   ready function        code shown false         div input   hide          lt  script gt   lt form action  javascript code toggle    gt     lt input type  submit  id  toggleButton  value  Show Code  gt   lt  form gt    Then simply export the notebook to HTML  There will be a toggle button at the top of the notebook to show or hide the code    Chris also provides an example here   I can verify that this works in Jupyter 5 0 0  Update  It is also convenient to show hide the div prompt elements along with the div input elements  This removes the In       and Out       text and reduces the margins on the left

This is now possible directly from nbconvert as of version 5 2 1  content can be filtered using the built-in template exporter exclude options  For example   jupyter nbconvert --to pdf --TemplateExporter exclude input True my notebook ipynb   will exclude the  input code  cells  ie the code itself  Similar options exist to exclude prompts  markdown cells  or outputs  or both inputs and outputs    These options should work irrespective of output format

jupyter nbconvert yourNotebook ipynb --no-input --no-prompt  jupyter nbconvert yourNotebook ipynb This part of the code will take the latex file format of the jupyter notebook and converts it to a html --no-input This is like a parameter we are saying during conversion that dont add any inputs   here the input to a cell is the code   so we hide it --no-prompt Here also we are saying  During conversion dont show any prompts form the code like errors or warnings in the final HTML file   so that that html will have only the Text and the code output in the form of a report      Hope it helps
