-Hello friends and welcome to the tutorial on Input/Output
-
-{{{ Show the slide containing title }}}
-
-{{{ Show the slide containing the outline slide }}}
-
-Input and Output are used in almost every program we use.
-In this tutorial, we shall learn
-
- * Outputting data
- * Taking input from the user
-
-type
-::
- 
-    a = "This is a string"
-    a
-    print a
-     
-print a prints the value of a which is obvious.
-As you can see, even when you type just a, the value of a is shown.
-But there is a difference.
-
-Typing a shows the value of a while print a prints the string. This difference
-becomes more evident when we use strings with newlines in them.
-type
-::
-
-    b = "A line \n New line"
-    b
-    print b
-
-As you can see, just typing b shows that b contains a newline character.
-While typing print b prints the string and hence the newline.
-
-Moreover when we type just a, the value a is shown only in interactive mode and
-does not have any effect on the program while running it as a script.
-
-We shall look at different ways of outputting the data.
-
-print statement also accepts the syntax of C's printf statement.
-Various arguments can be passed to print using modifiers.
-type
-::
-
-    x = 1.5
-    y = 2
-    z = "zed"
-    print "x is %2.1f y is %d z is %s"%(x,y)
-
-As you can see, the values of x and y are substituted in place of %2.1f and %d
-
-{{{ Pause here and try out the following exercises }}}
-
-%% 1 %% What happens when you do print "x is %d y is %f"%(x)
-
-{{{ continue from paused state }}}
-
-We see that the int value of x and float value of y are printed corresponding
-to the modifiers used in the print statement.
-
-We can also see that print statement prints a new line character at the end of
-line, everytime it is called. This can be suppressed by using a "," at the end
-print statement.
-
-Let us see this by typing out following code on an editor as print_example.py
-
-{{{ open an editor }}}
-type
-::
-
-    print "Hello"
-    print "World"
-
-    print "Hello",
-    print "World"
-
-Now we run the script using %run /home/fossee/print_example.py
-
-As we can see, the print statement when used with comma in the end, prints a
-space instead of a new line.
-
-Now we shall look at taking input from the user.
-We will use the ~~raw_input~~ for this.
-type
-::
-
-    ip = raw_input()
-
-The cursor is blinking indicating that it is waiting for input    
-type
-::
-
-    an input
-
-and hit enter.
-Now let us see what is the value of ip by typing.
-::
-
-    ip
-
-We can see that it contains the string "an input"
-
-{{{ Pause here and try out the following exercises }}}
-
-%% 2 %% enter the number 5.6 as input and store it in a variable called c.
-
-{{{ continue from paused state }}}
-
-We have to use the raw_input command with variable c.
-type
-::
-
-    c = raw_input()
-    5.6
-    c
-
-Now let us see the type of c.
-
-::
-
-    type(c)
-
-We see that c is a string. This implies that anything you enter as input, will
-be taken as a string no matter what you enter.
-
-{{{ Pause here and try out the following exercises }}}
-
-%% 3 %% What happens when you do not enter anything and hit enter
-
-{{{ continue from paused state }}}
-
-::
-
-    d = raw_input()
-    <RET>
-    d
-
-We see that when nothing is entered, an empty string is considered as input.
-
-raw_input also can display a prompt to assist the user.
-::
-
-    name = raw_input("Please enter your name: ")
-
-prints the string given as argument and then waits for the user input.
-
-{{{ Pause here and try out the following exercises }}}
-
-%% 4 %% How do you display a prompt and let the user enter input in a new line
-
-{{{ continue from paused state }}}
-
-The trick is to include a newline character at the end of the prompt string.
-::
-
-    ip = raw_input("Please enter a number in the next line\n> ")
-
-prints the newline character and hence the user enters input in the new line
-
-{{{ Show summary slide }}}
-
-This brings us to the end of the tutorial.
-we have learnt
-
- * How to print some value
- * How to print using modifiers
- * How to take input from user
- * How to display a prompt to the user before taking the input
