EOF is a special out-of-band signal which means the end of input. It's not a character (though in the old DOS days, 0x1B acted like EOF), but rather a signal from the OS that the input has ended.

On Windows, you can "input" an EOF by pressing Ctrl+Z at the command prompt. This signals the terminal to close the input stream, which presents an EOF to the running program. Note that on other OSes or terminal emulators, EOF is usually signalled using Ctrl+D.

As for your issue with Sublime Text 2, it seems that stdin is not connected to the terminal when running a program within Sublime, and so consequently programs start off connected to an empty file (probably nul or /dev/null). See also Python 3.1 and Sublime Text 2 error.

I had the same problem  The problem with the Sublime Text s default console is that it does not support input    To solve it  you have to install a package called SublimeREPL  SublimeREPL provides a Python interpreter which accepts input   There is an article that explains the solution in detail   GitHub page for SublimeREPL

try      value   raw input       do stuff value    next line was found  except  EOFError      break  end of file reached   This seems to be proper usage of raw input when dealing with the end of the stream of input from piped input   Refer this post  1

help input  shows what keyboard shortcuts produce EOF  namely  Unix  Ctrl-D  Windows  Ctrl-Z Return      input  prompt   -  string      Read a string from standard input   The trailing newline is stripped    If the user hits EOF  Unix  Ctl-D  Windows  Ctl-Z Return   raise   EOFError  On Unix  GNU readline is used if enabled   The prompt   string  if given  is printed without a trailing newline before   reading    You could reproduce it using an empty file     touch empty   python3 -c  input     lt  empty Traceback  most recent call last     File   lt string gt    line 1  in  lt module gt  EOFError  EOF when reading a line   You could use  dev null or nul  Windows  as an empty file for reading  os devnull shows the name that is used by your OS     python3 -c  import os  print os devnull    dev null   Note  input   happily accepts input from a file pipe  You don t need stdin to be connected to the terminal     echo abc   python3 -c  print input     -1    cba   Either handle EOFError in your code   try      reply   input  Enter text   except EOFError      break   Or configure your editor to provide a non-empty input when it runs your script e g   by using a customized command line if it allows it  python3   f   lt  input file

It seems as of now  the only solution is still to install SublimeREPL   To extend on Raghav s answer  it can be quite annoying to have to go into the Tools- SublimeREPL- Python- Run command every time you want to run a script with input  so I devised a quick key binding that may be handy   To enable it  go to Preferences- Key Bindings - User  and copy this in there           keys    ctrl r           caption    SublimeREPL  Python - RUN current file        command    run existing window command         args                          id    repl python run                file    config Python Main sublime-menu                       Naturally  you would just have to change the  keys  argument to change the shortcut to whatever you d like
