EOFError EOF when reading a line

Question

I am trying to define a function to make the perimeter of a rectangle  Here is the code   width   input   height   input   def rectanglePerimeter width  height      return   width   height  2  print rectanglePerimeter width  height     I think I haven t left any arguments opened or anything like that

The best is to use try except block to get rid of EOF    try      width   input       height   input       def rectanglePerimeter width  height          return   width   height  2      print rectanglePerimeter width  height   except EOFError as e      print end  quot  quot

width  height   map int  input   split    def rectanglePerimeter width  height      return   width   height  2  print rectanglePerimeter width  height     Running it like this produces     echo  1 2    test py 6     I suspect IDLE is simply passing a single string to your script  The first input   is slurping the entire string  Notice what happens if you put some print statements in after the calls to input     width   input   print width  height   input   print height    Running echo  1 2    test py produces  1 2 Traceback  most recent call last     File   home unutbu pybin test py   line 5  in  lt module gt      height   input   EOFError  EOF when reading a line   Notice the first print statement prints the entire string  1 2   The second call to input   raises the EOFError  end-of-file error     So a simple pipe such as the one I used only allows you to pass one string  Thus you can only call input   once  You must then process this string  split it on whitespace  and convert the string fragments to ints yourself  That is what   width  height   map int  input   split      does   Note  there are other ways to pass input to your program  If you had run test py in a terminal  then you could have typed 1 and 2 separately with no problem  Or  you could have written a program with pexpect to simulate a terminal  passing 1 and 2 programmatically  Or  you could use argparse to pass arguments on the command line  allowing you to call your program with  test py 1 2
